That's more or less what I used to do, but the problem of just using the relative humidity percentage is on a really humid day the background humidity level in the house can be higher than the threshold I've set the fans to turn off at (I live by the coast).

My current setup turns the fans on when the bathroom is 4g/m3 higher than the stairs, and off again when it drops below 2. This seems to work a lot better apart from the slight inaccuracy between the two sensors which means I have to set the trigger a bit higher than I would otherwise.

My initial thought is just do an offset to calibrate one sensor to the other every so often, but I could potentially do it automatically at a time when I'm confident the bathroom should be about the same humidity as the rest of the house.

That blueprint works fine - it uses a derivative (change in humidity)

Why not just calibrate the device? If it's the ZigBee ones it has an option for it and I'd guess they all do

This is what I have done with my zigbee devices in zigbee2mqtt and esphome, cant see why HA would not allow this in every protocol, as all sensors need it.

That's effectively what I'm trying to do, but hadn't realised there was a built in way to do it. I'm using Sonoff SNZB-02's with Z2M, and looking at the compatibility table it does have a "humidity_calibration" value, but how do I use it?

I failed to spot is the was the derivative, as it mentioned percentage. My old method was to trigger by relative humidity difference, which means setting the upper and lower thresholds, if that's tracking the rate of change of relative humidity it makes more sense.

I'm trying a slightly different approach, my fans are for the whole house (mechanical extraction ventilation) I trigger them on humidity in the bathroom, temperature or humidity in the laundry room, and if the kitchen extractor hood is open or closed, so using the temperature/humidity difference between two locations works well so long as the sensors are reasonably consistant.

In the z2m interface click on the device then settings (specific) then enter a number in Humidity calibration

FFS, that's a bit simpler than I expected, I'll give it a go tonight, thanks

Can you set it to a variable/helper? I'm wondering about setting it up to automatically set itself to match one of the other sensors at 5am or so when I can pretty sure the humidity will have evened out.

Just check the history when you get up in the morning, see what the difference was at 5am. No need to over complicate it.

New to HA, takes a little while to get to grips with it doesn't it...

Is anyone familiar with installing Python packages? I've got the HA terminal available and have been able to install most things via apk, inlcuding pip I think. But I cannot for the life of me get dateutil.parser working. Terminal says:

~ pip3 install python-dateutil       
Looking in indexes: https://pypi.org/simple, https://wheels.home-assistant.io/musllinux-index/
Requirement already satisfied: python-dateutil in /usr/lib/python3.12/site-packages (2.9.0)
Requirement already satisfied: six>=1.5 in /usr/lib/python3.12/site-packages (from python-dateutil) (1.16.0) 

Yet when loading my script it says this requirement isn't met.. I only know enough Python to be dangerous, as may be apparent..

I got this working last night, are you still struggling? I was a little gutted to see this already existed as I built a screen scraping python script to do it

[wombleh]

It might be that you're running that command as a "normal" user, in which case pip just puts the libraries in that one users home directory. You could try "sudo pip3 install python-dateutil" which should run it as root and make it available to everyone.

Are you using HAOS standalone on a Raspberry PI? In that environment, you might need to use docker to get yourself a shell in the container that is running HA before installing anything. Certainly with SSH access, if you just install a package in the container that the terminal initially lands you in, HA itself can't see it.

[Jambo85]

Thanks both. Unfortunately sudo doesn’t change the outcome. I’m running it on an HP T630 with the generic X86 64 install, so I don’t think its in a different container but happy to be corrected?

[HantsRat]

Only recently got into Home Assistant and have now hardwired in a tablet to the mains for a hallway dashboard. Mrs and everyone that comes round comments on how cool it is.

So i've decided to get a 2nd one for upstairs haha! Currently using a Lenovo M10 tablet. Great little things and only £99 as 45% off - https://amzn.to/3UWwiyq

I then hardwire them to the mains use use this Sonoff relay to control power and charging of the tablet (Turn off at 80%m turn on at 20%) - https://amzn.to/3UZd8Yp

Definitely looking forward to going deeper down the rabbit hole with this HA stuff!

I tried to change my Zigbee channel the other night (default when I set up was 11), however when I change it, Z2M refuses to load because the configuration isn't the same as the backup.

Where is the backup file stored? I have a code editor in HA but it's not showing any kind of backup file under Z2M.

Also I've seen a few posts saying channel 26 can be a problem and lots of people use 25, anyone know any reason not to use 26?

Have you seen this about channels?

Is the backup in /config/zigbee2mqtt ?

[RizzoTheRat]

I've certainly seen similar ones, that's why I want to move up to 25 or 26. That article says some devices don't support 26 but no idea how old it is, most (maybe all) of my devices are Zigbee 3.0 so no idea if that's still a problem.

Annoyingly my mesh wifi (Deco) doesn't let me specify the channel so I can't keep them away from the Zigbee channel


Would my code editor only be showing me the main files and not the backups? What's the best way to access the files otherwise? I'm running HA in a VM on a Synology NAS if that makes any difference

[Trustmeimadoctor]

i really should read the manual i just found the helpers menu

now i have easy to see min max and average room temps yay
