1. Kamstrup Omnipower with HAN interface enabled. (Kontact your Electricity company for them to enable this)

2. Windows 10, with installed VSCode and PlatformIO

3. An ESP32DEV board, I used this from AliExpress: https://www.aliexpress.com/item/32849567377.html?spm=a2g0s.9042311.0.0.27424c4dcQpFO7 but other can be used, you just have to be aware of the different pin-outs on the different boards.

4. USB Cable to attach to the ESP32DEV board

5. MQTT server (I am running on a Synology NAS in docker) If you have a Synology NAS, I can recommend to follow BeardedTinker on YouTube, he makes a very intuitive explanation how to setup the whole environment on Synology.

6. You will need the following in your configuration.yaml file:

   python_script:

   mqtt: broker: 192.168.1.64

   discovery: true
