Whoooooa awesome! I just started adding a ton of independent scripts for a new ZigBee thermostat and it was getting messy fast.
Can't wait to tinker with this next weekend!

Update. After installing and basic setup, I woke up to a toasty house and the heater running practically alllll night.
PG&E is going to ream me with a hot poker this month. Oopsie!
Note to others: set reminders to do periodic testing. Don't just go to sleep like me. Haha!
yes, you should definitely check regularly if the Automation does what you want, there are some stumbling blocks e.g. Difference of presence detection and persons. I spent about a month until I've understand enough so that it does what I want :)
Reminds me of the time I didn't realise that my underfloor heating had week/weekend heat settings, and woke up to a 24 degree basement.
I need to look into this again. I had it installed at the beginning of the winter and found it wonky. Heating during peak hours and not doing a thing when we pay .02$/kWh
Two cents per kWh?? Where the hell are you?
In Ontario! The new optional Ultra-Low Overnight price plan provides:
Ultra-low overnight rate of 2.4 cents per kWh: everyday 11 p.m.-7 a.m.
Mid-peak rates of 10.2 cents per kWh: weekdays 7 a.m.-4 p.m. and 9 p.m.-11 p.m.
On-peak rates of 24.0 cents per kWh: weekdays 4 p.m.-9 p.m.
Weekend off-peak rates of 7.4 cents per kWh: weekends and statutory holidays 7 a.m.-11 p.m.
I definitely take advantage. I have solar panels that generate a moderate amount of energy, heat pump, and electric (heat pump) furnace and hot water tank plus two electric cars. Home Assistant has been such a dream to maximize the low energy and self-generated energy.
I have debated adding some batteries, but the amount of energy we use, especially at -30 c, it's cost prohibitive.
Woah that is insanely cheap, that on peak rate though.... I could do Hilo here in Quebec but we work remote so I need the heat during the day I think we'd come out loosing.
Iβve been wondering about thermal storage for heat pumps but we donβt have time of use metering yet. I see a few options online but contractors arenβt familiar and itβs not even clear whether they are really available
My parents house when I was a kid had resistive heat, but they added thermal storage when our utility started doing time of use and it made a huge difference in the bills. However I donβt know the overall payback period
Hmm I might need this. Will look into.
I use this extensively.
I whish you could control many thermostats with many external termometers... But I need to run many copies of this automation, one for each room of my house!
Works very well.
That's exactly how I do it too, I think otherwise this automation would be too complex to handle (it is already very complex) π
Very nice! I'll have to take a look at this.
So far, I've only done some things with variable heating targets, boosting if one room falls behind, and minor adjustments on presence detection.
