Sonoff - WiFi Wireless Smart Switch for MQTT COAP Smart Home

Harry van der Wolf

Tools -> Advanced: switch on Rules. Then you can use them.

thanks

Did anyone use GPIO 14 (the spare pad on J1) to connect an external switch? I want to use this to switch the light locally, independent from the controller.

As the sonoff has a transformer it should be safe isn’t it? And the switch I want to use is a normal wall switch so that in insulated for these high voltages (if there are).

So, suppose you power the Sonoff with 230V and touch this pad 5. Will you touch mains or 3v3?

Hello,

I got my Sonoffs yesterday and tried to use them with MQTT. Config in attachment. Where is my bug?

Got some sonoff devices last week. I flashed them with Tasmota FW and all works well with the pimatic-mqtt-plugin. Also the status in pimatic is updating correctly over mqtt.
Big thanks @wutu

By default the device sends every 5 minutes the energy data. You can change this interval with the command TelePeriod <seconds>in the console or by url http://<ip>/cm?cmnd=TelePeriod <seconds>

Sonoff 4CH for DIN Rail (Hutschine)

This device has a ESP8285. When flashing with Arduino, select “Generic ESP8285 Module” as boardtype. It seems that the labeling for TX/RX on the circuit board are reversed. I had to connect TX<–>TX RX<–>RX.

Anyone tried this one?

@DanielHecker does the sensor connect to the broker?

This is the topic where the sonoffPOW (tasmota fw) publish the energy values as json string.

Exampel message:

tele/pow1/ENERGY = {"Time":"2017-02-15T11:16:20", "Yesterday":0.012, "Today":0.000, "Period":0, "Power":4, "Factor":0.35, "Voltage":230, "Current":0.050}

Sonoff POW and TH16 are not safe!
Yesterday a SonoffPOW begun to smell like burnt electronics. Fortunately, my wife was at home and pulled the plug in time.The housing starts to melt. The POW was connected to a washingmashine but the current flow was never more then 16A.
