Got my LDO the wrong way around!
Disaster! I finally got around to putting some components on the latest version of my Dual Temperature PCB. Unfortunately, I found a huge mistake! The Module I started assembling the board with the MinewSemi nRF54L15 module. I made a better first pass with this than I did with the DevKit.… Read ⇢

Adding Power Forecasts to my Matter Heat Pump
In this post, I created a basic Heat Pump implementation using Matter-JS. Building on this, I wanted to add support for power forecasting and schedules. This would then allow me to show how energy management might work for heat pumps. This would be similar to what I did for my… Read ⇢

Mass Flow Rate, not Room Temp – tweaking my Heat Pump Maching Learning Model
Almost two months ago, I wrote a blog post outlining how I built a Machine Learning model for ASHPs. Powered by the data from OpenEnergyMonitor, it was quite basic. It used the Target Temperature and the Outdoor temperature to predicate energy consumption. It was my first go at Machine Learning… Read ⇢

Running my Matter Dual Temp Sensor on a MinewSemi ME54BS01
With my initial PCB designed and my code working on the Nordic DevKit, I turned attention to my ME54BE01 devkit. This board comes from MinewSemi and is designed to support their nRF54L15 modules. Yes, I should have gotten my code working before getting PCBs made, but I figured it should… Read ⇢

Testing my MinewSemi ME54BS01 and ME54BE01 DK
As part of my efforts to build a Matter powered dual temperature sensor, I was hunting for a Nordic nRF54L15 Module to use on my PCB. I had already looked at the HolyIoT board with some success. Next on my list was the MinewSemi ME54BS01 module and dev kit. This… Read ⇢

Porting my Zigbee Dual Temperature Sensor to Matter on nRF54L15
Something that’s been on my TODO list for a long time is to convert my Zigbee Temperature sensor to Matter. I’ve written quite a few blog posts about the development of my Zigbee “FART” sensor. If you want to read more about that, you can start here: https://tomasmcguinness.com/2024/12/09/switching-my-temperature-sensor-from-ble-to-zigbee-part-1/ The Goal… Read ⇢
