can Gpio switch not direct action? #84

Closed hamwong closed 7 years ago

hamwong commented 7 years ago

can Gpio switch not direct perform relay action and publish status to MQTT?

davidelang commented 7 years ago

I think it does that if it's not able to reach a mqtt server

hamwong commented 7 years ago

on my test environment, I got MQTT online, only result is switch direct turn on/off relay and post MQTT, I wish there is an option don't switch relay and post MQTT, let server - openhab decide on or off,

davidelang commented 7 years ago

you can set the button to send a different message, that's what the switchtopic is for.

set the button to send a different topic and openhab will make the decision.

Thanks @davidelang, as too many commands, and not much description on command usage, I didn't aware switchtopic for this usage, another issue come, is this is a bug or limit as if I got 2 gpio set for same function(switch). only one of gpio will work, other one won't function,

I set as below: {"GPIO3":9 (Switch), "GPIO4":0 (None), "GPIO14":9 (Switch)} than only GPIO14 works, GPIO3 no response, or the other way around.

I like to set itworks as below condition, GPIO14 connect to HC-SR501 PIR and work with MQTT (openhab), and GPIO3 work with wall switch (direct control), so that user may manually overide on/off and not from PC/mobile.

as far as I test, I only may work out as switch + DHT22 on GPIO 3,14, but not both switch.

https://github.com/arendst/Sonoff-MQTT-OTA-Arduino/issues/158

I injected some codes into the firmware that read the GPIO then published on /stats/sonoff/GPIO topic. Then I could implement this: https://nayarweb.com/blog/2017/iot-series-smart-lightsensors-in-the-kitchen/

I need to rewrite the patch and maybe merge it upstream

Hi @Nayar Thanks, I am so excite that this feature will come, I look at #158, does that mean I can assign GPIO14 connect to HC-SR501 PIR and work with MQTT (openhab), and GPIO3 work with wall switch (direct control)?
