Get the values of ViCare Solar Sensor

moppes · February 20, 2021, 9:15am

Hi there,

I am using the ViCare AddOn (https://www.home-assistant.io/integrations/vicare/). Per default it shows my water heating circuit. So far so good. Would it be possible to get the temperature of my Solar collector?

If yes, what should I configure, how to set up?

Thanks and cheers!

Anyone who can help? I have the same question.

Have those values been added to the API in the meantime? If yes, what do I need to do to update my configuration? By now I am still missing those sensor values.

It’s on its way…

Hi @Bernhard-h , I was so excited to read that you got the ViCare solar sensor integration to work, but I see that you closed the pull request and it was not merged. Are there any issues, or can I can help with anything (testing, creating another PR etc.)?
Thanks a lot.

Hi Thomas,
all good, thanks - I ruined the pr on my side and thus had to file a new one.
See here: Add vicare solar collector and pump information by bairnhard · Pull Request #64178 · home-assistant/core · GitHub
I’d be happy if you can help by reviewing it and getting it through faster.

Best

Awesome Bernhard, thanks a lot for your efforts. Looks like I was a bit too late for testing & reviewing, now there’s only the maintainer’s review left. Let’s keep our fingers crossed

Hi @Bernhard-h , I tested your code and it runs great, thanks for contributing! Do you know if we can also get the pressure data for the solar cycle, or even for the main heater circuits? I tried to read it using vcontrold, but I have not been able to find any pressure information.

Hi @tosch ,
we’re using pyVicare to get the data and there’s, unfortunately, no pressure information available:

If Viessmann provides that information in your config, you might add it there and then in HA, I can’t see this info in my ViCare app, so my heating system just does not provide that information.

There’s no pressure information in my config either, nor in my ViCare app, so I guess I’m just out of luck here Anyway, thanks for checking Bernhard!
