Let's Control It

Hello,

I have an Arduino with a pressure transducer connected to it like this. I also have a Nodemcu running Espeasy connected to an openhab server via MQTT. How can i send pressure data from Arduino to Nodemcu so it can send it along via MQTT?

Thanks

Maybe take a look at the "MiniProExtender".

It's an Arduino Nano used as a GPIO Extender for ESPeasy.

Why not connecting the sensor directly to Nodemcu?

@sentinel, thanks for the link. I will create a separate post about that.
