I have added a simple On/Off State Widget in the thinger.io Dashboard to control the relay on my Sonoff device.
If I try to set the Widget to On it immediately goes back to Off (and the relay also goes On to Off).
I get the same “on then immediately off” behaviour if I trigger a Web Request from IFTTT Maker channel to turn the relay On.
However if I control the relay through the API Explorer everything works as it should.
What am I doing wrong?
