When I press the heatlamp switch, the light switchs to off immediately. Only when I toggle the switch at Openhab the light stays on.
Did I something wrong?
Is your device really named “sonoff”,would be weird if you have more then one and it is a Shelly not a Sonoff.
If the device is has only one switch (Shelly1?) there is no Power1, it is only POWER (uppercase)!
The problem still exists. When i’m pressing the heatlamp switch the light turn on and off immediately.
Do I have to configure teh switch type like here?
What is the "heatlamp"or “headlamp switch”? A hardware switch on the Shelly? Does the Shelly have such?
Where is that copied from? Does it relate to Tasmota? You did flash your device to Tasmota ( the web interface shown is from Tasmota!)
You can use the web interface to monitor which messages/commands are received by the Shelly. Use the Console on the Main page.
