"Unknown" values shown in Home Assistant (Itho HRU)

[maerten]

The values of the Itho HRU sensors are not showing up in my Home Assistant UI.
In MQTT I do see the ithohru/ithostatus values, and also the default "Fan" entry from the Itho MQTT integration works.

Any help would be greatly appreciated :)

Problem details, HRU sensor values showing as "Unknown"

What specific model Itho device is this?

It seems that your HRU provides different (formatted) data compared to the HRU definitions that we know and on which the integration is currently build. We will look into the options if/how to support your specific model.

Could you supply us with a full copy of the supplied value from the ithohru/ithostatus topic?

Perhaps it is an older device? This is in an appartment building from 2012.

[benjamin-dcs]

Could you this release a shot?

If you are using HACS, you can Re-download this release as a specific version. Might require to 'Update information' first

[maerten]

Thanks, let me try

[maerten]

Should I still use ithohru for the MQTT base topic?

After installing 2.2.0-b1 i added both HRU types:

After that I saw these entities:

[benjamin-dcs]

Guess there's some bugs left 😉. You'll need to use the non-350 one. Does that bypass sensor work?

I'm going to redo quite some logic for these devices, so you will need to reconfigure once that's done, but that shouldn't be a huge problem for now

[maerten]

Thanks!

Does that bypass sensor work?

no idea, but if the value is included in the integration I can monitor it and report back :)

[maerten]

I was just trying to install the 2.2.0-b2 test version.. something went wrong so i had to reinstall it, but i think it was just removed? 🤔
i'll check again tomorrow. thanks for adding support for it!

[maerten]

Oh now its back.. i'll try again
Update: i tried installing but it keeps install 2.1.. looks like HACS can't find the 2.2.0-b2 version

[benjamin-dcs]

Try now (2.2.0-b2)

[maerten]

The temperature fields are working now, but the fan speeds aren't.

[benjamin-dcs]

Due to some copy-pasting those grey entities are disabled by default. I'll fix that for the ones that shouldn't. For now you can click on the entity and enable it

[benjamin-dcs]

Also, please let us know if there are any sensors you would like to be included (of course they need to be available in the data you provided earlier). We will see if we see them fit

[maerten]

Ah ok i will try that. Thanks for adding support so quickly!!

[benjamin-dcs]

Your air filter counter isn't working by the looks of it. Will look into that aswell. Probably a 'config' mistake

[maerten]

Also, please let us know if there are any sensors you would like to be included (of course they need to be available in the data you provided earlier). We will see if we see them fit

Well there are quite a few values listed in the Itho Addon that might be interesting. Although its not clear to me how to interpret them, and what they mean.

For example: boiler timer, valve position, frost timer, etc.

I was mostly interested in the fan speed, so I'm happy with the current state of things :)

[benjamin-dcs]

2.2.0-b3 should fix your air filter counter
(Other changes are less visible)

[maerten]

Thanks
Do I need to remove all devices before updating?

[benjamin-dcs]

No, you can just update

[maerten]

That works 👌

[benjamin-dcs]

Hi @maerten, I just released v2.2.0-b4. This is a very big update, which needs some love at code-level. However should function. Please try. Any feedback is more than welcome. I believe, in your case, you will need to remove the current devices and reconfigure them again.

[maerten]

Interesting!
I'm trying to install it, I downloaded op v2.2.0-b4, but somehow HA is picking up v.2.1.0

(It is also not asking to specify the HRU type when adding a device)

[jasperslits]

That's because the tag for v2.2.0-b4 was created 3 weeks ago, before the latest changes.

@benjamin-dcs : can you fix that?

[benjamin-dcs]

Please try v2.2.0-b4 again

[jasperslits]

LGTM now

[maerten]

Yep it works 👌

[benjamin-dcs]

I published another update (v2.2.0-b5) with some extra fixes and code improvements. If possible, please update and provide feedback :)

[benjamin-dcs]

Hi! First of all, best wishes for 2025! We just released official version 2.2.0. In case you installed a 2.2.0-beta release you will miss quite some sensors after installing the official 2.2.0. This is due to an extra option we introduced after the last beta. See available-entities on how to reconfigure your integration entry and get all the entities back (if you so wish)
