    Home Assistant and nice statistics graphs

    One of the things that bothered me in #homeassistant for more than a year was the following: I couldn’t figure out why some entities/sensors can draw nice longterm statistics graphs like this (with average, max, min values): and some show only bulky history charts (10 days of data) like this: #til Today I learned I…

    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

    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.

    When did I change the batteries in my sensors?

    Last month I learned about the integration which helps track battery change status in various devices connected to #homeassistant.

After the installation and HA restart, it automatically found my #Aqara battery devices (#Zigbee buttons, magnetic door…

Moreover, all entities had duplicates in the entity list ending…

  • 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…

  • The water meter experiment failed successfully

    This, my dears, this is how to fail spectacularly:I wanted to measure my home’s water consumption and track it in Home Assistant. I failed (for now). Read on to find out what happens if you buy all the correct components, follow the instructions but fail to check the type of the water meter first. I’ve…

  • Regulacija ogrevanja z Aqara IoT

    Regulacija ogrevanja z Aqara IoT

     Kako najenostavneje regulirati ogrevanje z Aqara IoT pritiklinami? Pred kratkim sem hišni ogrevalni sistem razširil s četrto vejo, ki je namenjena ogrevanju kletne etaže in pisarne. Obstoječe 3 ogrevalne veje (talno, radiatorsko in bojler) mi uspešno krmili regulacija Seltron WDC20. Ta regulacijski sistem je poln – nima več prostih relejev, vhodov za senzorje, niti nima…
