Detecting movement in Home Assistant using Ikea Vallhorn sensor
I’ve bought some #Ikea #Vallhorn motion sensors for 8€ a piece. (see info here) Pairing to the #Zigbee network in #HomeAssistant and #Zigbee2MQTT was somehow difficult, which is not usual for Zigbee devices (at least according to my limited experiences with them). Nevertheless, I succeeded in pairing them. Unsuccessful attempts Firstly I tried to pair…

Simple tablet charge controller using Sonoff’s ZBMini
I’m using an Amazon #FireHD tablet stuck to my fridge with several magnets and 3D printed case as a #homeassistant dashboard. I read it’s bad for the tablet’s battery if it’s constantly plugged into a charger. Battery can swallow or worse.

Today I finally had some time to install #HACS integration (source) called ‘Battery Notes‘ which was written by Andrew.

How much electricity does 20y old dishwasher consume (Tuya Zigbee smart socket test)
Aliexpress Santa delivered a cheap (10€) Tuya smart socket (Zigbee version). I have several Aquara smart sockets (SP-EUC01) around the house that work really well in #homeassistant. But they cost 20-25€. I wanted to test the #Tuya smart socket this time. Not sure exactly which model it is, Aliex… markets it as “Homekit Tuya Smart…

Energy dashboards in Home Assistant
I spent quite some time configuring the Energy dashboard in #homeassistant. My primary objective was to track how much electricity my home consumes, how much my micro #PV produces and how much I return to the grid. Finally, this is the result: Today is a cold and sunny day, so my heat pump consumes a…

Tuya 3-phase energy meter and Home Assistant
The issue with spike power readings on phase B / So, if you bought a cheap (~70€) Tuya 3-phase zigbee energy meter (with 3 clamps), you’ve probably noticed strange readings on a phase B and C (39xxx W) in #homeassistant. See the spike: It happens to me when my micro-solar inverter exports energy to the…
