Good afternoon all,

    I have finally got around to documenting my journey in getting around the woeful controls that the destroyers installers installed when they put in my ASHP. I have used a Waveshare POE ethernet to modbus converter and now have full remote control of my ASHP. The next stage of my project is to build a self hosted AI agent probably using Mistral, N8N and MCP in order to create my own version of a Homely type controller.

If this floats your boat then I commit to thee: https://github.com/Si-GCG/Grant-Aerona3-modbus/tree/main

If you want to join in the fun let me know and I will happily share everything with you as I continue this journey.

Kind Regards

Si

Count me in @grantmethestrength

I have a Grant R32 13kw HP. So not the same model, but might be able to help.

Now heating season has finished, I am in the process of installing a 

RS232/485 To WiFi/Ethernet Module (Modbus/MQTT Gateway)

From PI hut. 

I am also looking at making changes to my buffer / pipe work and installing various flow meters and Emoncms energy meters into the mix.

Just starting out on the HA journey on a PI-4 for testing and a small PC for live workings

Pete

Hi Pete,

    I am also looking into getting more sensors as it is bonkers that they don't even install a tank thermometer! I have seen some active discussions on the openenergymonitor forums about AI integrations. I have just got ollama in a docker container and am trying to pull Mistral small 3.1 as I type (top Saturday night!).

I have recently watched

and am going to attempt to get this up and running when I get a chance, I think with various agents we should be able to better analyse the data and then make changes.

Regards Si

Not sure if that link is working but it is a video on Cole Medin's channel called

The MCP Integration EVERYONE is Sleeping On (MCP + Custom AI Agents)

Yes link works. Starting to work though it, but looks like I need to go back a couple of steps first to understand more
