Ah interesting, I've never read the instructions just hit "Dry"!
Don't forget to warm the room back up before checking the humidity or the cooler air might make you think it hasn't made a difference :).
On another note, I've always wanted to try home assistant but never got around to actually getting any equipment. What sensors did you get?
Yes good point! Doing a test now, set to dry, will check how it goes.
First of all, it can be a rabbit hole. Secondly, it's awesome. I've set it up on a Raspberry Pi, and set up a Zigbee mesh with the Home Assistant SkyConnect dongle from here. I bought some Sonoff temp sensors, and Sonoff Smart Sockets to increase the Zigbee network range. I've also bought some Smart Sonoff Bulbs at Aliexpress but I'm not very happy with them as they caused some Zigbee network issues. Seems to have resolved it by itself somehow.
Our heat pump is not a smart one, so I'm using a Broadlink RM3 Mini to control my heat pump. Works like a charm. That way I would also be able to set it to dry and heat on intervals of e.g. 1 hour during the night.
Any other questions just ask.
Oh boy, that's cheaper than I was expecting startup costs to be... I am oh so tempted now!
With HomeAssistant, as I understand it, it needs the full Pi? I have a bunch of services running on my RPi 4 and so when I've looked at HomeAssistant I haven't been able to install this without touching the other stuff on there. I think they have a docker container version but it has a lot less features.
I have for a while been intending to uprade my stuff to something that can handle photos/videos better, but haven't got around to it. I might need to wait until I do that, then I'll have a spare Pi to use for HA.
I'm guessing an RPi 1B won't handle it. It's running Pi hole at the moment, but I think this is about the only thing it's capable of.
Do you have any old x86 computers lying around?. I am running a NAS serving a dozen docker containers and a VM on an ancient 4th gen intel cpu. I never got into the home assistant stuff but maybe I'll also give it a go! I use PhotoView to share photos with family through CloudFlare zero trust tunnel.
Computers outnumber adults in our house by quite a bit, depending on what you count. There's one in particular that I think would make a good server, but it's a laptop and I can't find the power cord!
Other than that, the Raspberry Pi 4 handles many services just fine, it's just photo/video that are pretty slow (and gets worse the more you use it, so probably thermal throttling - it doesn't have a fan). But it turns out you can run Home Assistant in a docker container and still use the addons by connecting them in other docker containers, so I will give this a go once I get a chance.
I have an unused Pi4 4GB model lying around, I might try run HomeAssistant on it. Sounds like a fun project.
