Detecting movement in Home Assistant using Ikea Vallhorn sensor
I’ve bought some #Ikea #Vallhorn motion sensors for 8€ a piece.

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…
