Hi

I'm trying to set two relays at once, but only one changed.

I publish via Home Assistant MQTT:

relay32/xxxxxxxxxxxxx/set

{"relay17":{"on":1},"relay18":{"on":1}}



but only relay17 state is changed

please answer
Is it possible to set more than one relay by one MQTT publish command?

with regards,
Gene

I've been playing with H8B device today and connected a momentary switch to it's input port. I also use MQTT Mosquito to publish/subscribe for the events. Quite often I didn't get the button press reported as apparently they were too short. I have noticed that I have to press and hold the button for around 0.5 sec to get it reported. Is it an expected behavior? I'm planning to use some inputs for the door bell application and short button presses are normal. It almost look like some kind of a button debounce technique was applied for the input signal, but it affected how short signals are being recognized. Please advise.

Hello,

as per Request in Youtube Channel here a small Example List of IO´s needed per room excluding switches and Relais. This is just a Sensor list of Sensors that are typically used.

I hope you can see that Sensor inputs are always Welcome.

I have not added Analog Sensors that are usually mounted. If you need them i would add them too.

These are just some example rooms. Garage and Outside of house is missing too. Kids Bedrooms are the Same amount like normal Bedroom.

I hope this helps Kincony to understand why we need many Inputs.
