ESP32 – Modbus interface with an SDM120M
In this post, I explore how to setup an SDM120M energy meter with an ESP32. The SDM120M is a DIN mounted energy monitor, which can work with currents up to 42A. My goal is to use one with my upcoming heat pump installation, as part of my monitoring plans. Ultimately,… Read ⇢

Creating a Matter Controller with matter.js
Whilst I’m still chipping away at my .Net Matter Controller code (it’s really hard), I wanted to continue exploring the Energy Management capabilities of Matter. If I wait until I’ve fixed all the issues in my implementation, Matter will be obsolete 🙂 To that end, I decided to have a… Read ⇢
