Thanks for another quick reply.
There is 0V on the pin I gave 3.3V voltage and the state changed into the dashboard Thanks beautiful.
I will ask about one more aspect.
Sometimes, after disconnecting the voltage from the port, the dashboard still shows high status. An average of one in eight starts.
I started learning. Is it possible to control GPIO pins via MQTT on the same Raspberry without additional devices? Everywhere I see configuration examples for additional devices, e.g. ESP8266.
Maybe if you did a supervised install on Raspbian, though home assistant is a bit “clingy” about retaining exclusive control of the gpio port. Shouldn’t be an issue if you don’t use any gpio integrations.
I do not understand why this problem was not addressed. Home Assistant is great, but this bug is terribly problematic. Raspberry has so many GPIO pins and I can’t use them as input. I will try https://www.openhab.org/ with it maybe everything will work as it should.
I’m also not familiar with all these configurations and maybe that’s a problem too
