is anyone aware of a step by step installation guide I’m not sure i’m completing the installation process correctly.
Is anyone able to confirm if the relay boards I’m using are the correct ones ? to run from a pi gpio, Ive powered the board from a separate 5v supply and attached the pins to the relevant pi gpios, but it just doesn’t work… if i short the supply 5 v to any of the trigger inputs i hear the relays click no problem… does the Raspberry pi gpio give out 5v dc as an ON signal ?
Ok so I’ve got round to having a good play and I’ve got it working… sort off, the problem appears to be more home assistant end. when i press the switch within home assistant to turn ‘ON’ a message is published to gpio2mqtt and the relay turns on but then the problem is that shortly after the switch in home assistant is turned on it bounces back to the off position ( This isn’t published to MQTT ) if I’m quick i can press it on and then press off again before it bounces back and an ‘OFF’ command is published to gpio2mqtt and works no problem turning the relay off.
Ive used an example from off the forum just whilst I’m testing
I would like to install the HA in a Intel Nuc computer and use a remote Raspberry pi with some GPIO expander boards to control all the house inputs and outputs.
