Spent this morning beginning to automate my central heating, here’s what I’ve done:
Shelly 1pm replaced the apt wall clock that controlled the oil boiler (~€20 for the relay and €2 for the blanking cover)
Set up a zigbee network with zha/conbee ii (€35 for conbee stick, but this also now controls zigbee outlets and bulbs elsewhere)
Put a sonoff zigbee temperature and humidity sensor in every room (€11 per sensor, €66 all in)
Created a generic thermostat in home assistant linking the boiler relay to the master bedroom sensor (master bedroom is the room of most interest to regulate the temperature in atm as that’s where the baby sleeps)
Set up the following switches/automations in home assistant:
I’m waiting for a zigbee button to arrive in an ikea order on Monday that I’ll stick on top of the blanking plate where the apt timer was that will physically control the boost. I need to also set up an away mode to flick off the thermostat when we’re both away.
From a central heating perspective the next step is to pick up some zigbee trvs for each radiator to make it as close to multi zone heating as I can. I’ll probably pick up a single moes one to test and if all goes well I’ll order 9 more.
Its less urgent as the central heating is heating our water, but before summer comes I’ll wire a shelly 1 to a beefier relay/contactor to control the immersion.
