I’m always tinkering with the code so I might have modified it without actually running it 😉

Regarding the configuration of the broker and/or client take a look at this [post](https://community.homey.app/t/homeyduino-v2-0/6407/20)

At the time yes, but not anymore. Now I’m running node-red in docker from my NAS. I’m really impressed with the stability and performance of it.

On a side note I’m also using node-red to transform json payloads and pass the result to another topic. really nice actually!

Hi, got it all working now with several devices. Next step i’m considering is to create a 433Mhz version on a board without WiFi. This saves energy a collegue (not using Homey) told me. Any experience with this? Is MQTT still supported than? Different topic maybe?

You’d need a 433Mhz receiver that would receive the data sent by your device, and that receiver needs to be connected to WiFi (or at least a network) to be able to relay messages to the MQTT broker.

If your device only periodically has to send data (for instance, a temperature/humidity sensor that takes a measurement once every few minutes), you can consider using an ESP8266 that is put into deep sleep mode in between measurements, which will save a lot of power.
