PCF8574 support about sonoff-tasmota HOT 14 CLOSED

The Webserver one seems to be a bug I can correct easily tomorrow. Regarding the ElektroDragon this is more complicated because for the PCF I scan the I2C bus and any of the valid channels count as one PCF with 8 relays. I assume my algorithm detects the electrodragon as a PCF board. Can you share in debug log the start procedure. Maybe it helps to change the I2C address. Further investigation is required

Hello these are messages i get after reboot:

It seams that it detects first the correct situation and later it things there is one additional pcf8547.
i2scan gives:

17:08:48 MQT: stat/sonoff_ed1/RESULT = {"I2CScan":"Device(s) found at 0x3f"}
Best regards

Oh yes, this is interesting and for sure an unwanted behavior. I will try to fix this asap

from sonoff-tasmota.

The behavior is fixed and tested with the 6.0.0 upgrade

from sonoff-tasmota.

Where do i need now enable PCF8574 support?

from sonoff-tasmota.

No change to the old behavior. SCL and SDA must be defined and use_pcf8574 must be enabled. if at least one board is found during scan the webinterface will show a configuration page. Please see wiki.

#define USE_PCF8574

from sonoff-tasmota.

Thanks for fixing the bug. It works now.
But i recognized two curious MQTT messages. Switching relay 1 to 8 gives messages like this

Client mosqsub|4233-vdr received PUBLISH (d0, q0, r0, m0, 'stat/sonoff_ed1/RESULT', ... (16 bytes))
stat/sonoff_ed1/RESULT {"POWER3":"OFF"}
Client mosqsub|4233-vdr received PUBLISH (d0, q0, r0, m0, 'stat/sonoff_ed1/POWER3', ... (3 bytes))
stat/sonoff_ed1/POWER3 OFF

Relays 9 to 10 gives additional a domoticz message as follows:

Client mosqsub|4233-vdr received PUBLISH (d0, q0, r0, m0, 'domoticz/in', ... (58 bytes))
domoticz/in {"idx":1950,"nvalue":1,"svalue":"","Battery":89,"RSSI":10}
Client mosqsub|4233-vdr received PUBLISH (d0, q0, r0, m0, 'stat/sonoff_ed1/RESULT', ... (16 bytes))
stat/sonoff_ed1/RESULT {"POWER10":"ON"}
Client mosqsub|4233-vdr received PUBLISH (d0, q0, r0, m0, 'stat/sonoff_ed1/POWER10', ... (2 bytes))
stat/sonoff_ed1/POWER10 ON

Is this a feature or a bug?

from sonoff-tasmota.

Hm, sound not like a cool feature. therefore i would vote for a bug.
Let me guess you have defined 2 RELAYS and the 8 RELAYS on the PCF. Therefore 1 and 2 should be normal and 3-10 should be executed by the PCF functions.

from sonoff-tasmota.

Ok, updated some functionality. The new behavior is now that the GPIO relays are first in the list. the the PCF relays show up. This has not changed so far. In the Standard configuration, 4 devices are defined for domoticz. The first 4 Relays are assignable. Changing this setting should allow to enhance it to more relays:

#define MAX_DOMOTICZ_IDX 4 // Max number of Domoticz device, key and switch indices

from sonoff-tasmota.

You are guessing right. relay 1 and 2 are connected to gpio's and 3 to 10 to the PCF.
I don't need any Domoticz messages, how to disable them? It was curious to see, that
these messages where generated only for relay 9 and 10.

Your updated software i will try later.

from sonoff-tasmota.

you can either #undef USE_DOMOTICZ and or set all indexes to 0 on the config page

from sonoff-tasmota.

There is still somezhing strange:

As you can see PCF is detected but the 8 relays don`t show in the webui.

from sonoff-tasmota.

please goto CONFIGURATION -> Configure PCF8574 and set the Relays to OUTPUT. Done

from sonoff-tasmota.

Thanks it works now. It was my fault. I forgot that I had to do the configuration from scratch,
because of compilation for 4M flash to be able to do OTA agin.
