As you may have noticed, it’s summer. And boy do we love to complain about the heat here in the UK! It’s one of those cultural things that brings everyone together, like the World Cup, which just so happens to be going on now (come on England).
But who wants to be sat in a very hot house, trying to watch their team win each and every match? No one.
So I took to the task of making sure the house stays cool while I relax!
It all starts with the FP300. Not just a presence sensor, but a light and temperature one as well. If the room gets too bright, or the temperature gets too warm, it knows about it. Perfect for what we need.
In Home Assistant, I take the data from the FP300 as a trigger, and have it validate the room temperature against other sensors in the room (you never know, I might be using a hairdryer stood in the corner of the room for some reason). In this case, we’re using the Aqara E1 TRV.
Great, it’s definitely warm in here if both are reading above the set temperature. Now the house jumps into action. First, we have the Aqara E1 curtain drivers close the curtains to block out the heat and keep the room from getting any warmer. Next, the H2 Wall Socket flicks on the connected fan, to get the room circulating! Hopefully things cool down before the Panama match on Saturday!
Here’s the code I use to trigger this automation in Home Assistant, you just need to update the names to your devices.
Bonus:
You could take this one step further, if you have an Air Con unit with an IR remote, and one of the Aqara Hubs (M2, M3 G3) that have an IR Blaster, you could have that turn on with the same triggers and not even have to incorporate it into Home Assistant!
Do you have any summer heat automations? How would you improve on this setup? I’d love to hear your feedback!
