Adding AllJoyn support out of the box for OpenSprinkler could really help integrating it with the future of Home Automation. The work required with the provided tools by the AllSeen Alliance is actually not that big.
Define all the methods, events and properties the sprinkler should expose using the XML introspection API and most of the code and interfaces are completely autogenerated for you, for a quick follow-on implementation of the interfaces.

Starting interval_program's ospi.py throws a KeyError.

Possibilities to deal with small gaps (1-3 frames) in cell tracks due to inappropriate cell detection?

• Kalman filter ?

Normal loop:
unsigned long water_time = (unsigned long)water_time_decode(prog.durations[sid]);
// if the program is set to use weather scaling
if (prog.use_weather)
water_time = water_time * os.options[OPTION_WATER_PERCENTAGE].value / 100;
pd.scheduled_stop_time[sid] = water_time;

Manual start:
else if(pid>0)
dur = water_time_decode(prog.durations[sid]);
if (dur>0 && !(os.stndis_bits[bid]&(1<<s))) {
pd.scheduled_stop_time[sid] = dur;

Shouldn't we be scaling the duration in a manual start by the weather setting?

Hello,

When using master valve it supposed to power up wit any other valve. In reality it only powers up work valve.
Can you please look into it?

Thank you.

It's silly to store a tarball of code in git (makes it hard to collaborate too).

Please just store the source.

I have been able to get the OpenSprinkler firmware (with some modifications) to work on an ESP-01 controlled relay board like the ones shown at these link:
AliExpress Link
Amazon Link

The trick with these boards is that the relay is controlled by sending a 4 byte binary code on the serial line 115200/8/n/1 from the ESP module (there is another non-reprogrammable MCU on the board that listens to the serial commands and controls the relays). e.g to turn on relay 1 on you send the 4 byte hex code a0, 01, 01, a2. To turn it off you send a0, 01, 00, a1 (so it looks like the first byte a0 is a delimiter, then the second byte is the relay number, the third is on or off, and the last byte is a checksum).

I have also found that I need to add a 20msec delay between controlling different relays for them to reliably switch.

There are many other boards like this, with differing numbers of relays (I have seen single channel relays and 2 channel relay boards).

With these boards, all you likely need to add is a full bridge rectifier with a buck converter to power the board from the solenoid 24V relay line, and you have a very inexpensive headless WIFI sprinkler controller (no display or buttons, you need to rely on the phone/browser interface).

I would love it if support for this type of board could be added to OpenSprinkler. I got mine working by hacking the switching logic for the RF station type in OpenSprinkler::switch_rfstation to send the appropriate serial command. To do it properly, you would have to add a new station type (perhaps named Serial Binary, or something like that), where you specified the binary sequence to send to turn the relay on and the sequence to turn it off. That would require updates to the ui code which is out of my league (hence I only co-opted the RF station type in my copy of the code).

Is this something that you would consider adding?

PS: the forum seems to be broken, as that may have been a more appropriate place to post this, but whenever I am logged in, the forum links give me Page Not Found error, preventing me from being able to post.

Hi,

I created a web interface and a server to run on Raspberry Pi to use the OpenSprinkler system. I've use the sample code from this repository to base my work on.

I'm preparing to release the application I wrote under GPLv3 and want to make sure it will not create any conflicts. Can you please tell me what license you sample codes are under?

Thanks.
