Hi all,
I have written a really basic tool to take MQTT messages from a local broker and push the values into the AIDA64 custom registry keys.
Project is really early doors but it does work, I am using it to read MQTT messages from a Tasmota power plug to give my sensor panel a total power usage value.
Feel free to take a look here, hopefully it is of use and I can work on it further.
