Help me keep the faith with my air source heat pump installation

AdamK · 2025-03-29T13:05:20Z

i knew when setting out on this road it would be a challenge i just didnt know how much of one it would be. after having many quotes some i couldnt fathom why they were so high i thought id sorted an installer. problem is they are 72miles away so first issue was doing a remote heat loss which has been back and forth several times to get it more or less correct, but still have one room thats 2m2 smaller than what i measured. anyway the next issue was getting the 28mm primaries in before the new kitchen ceiling goes in. they sent a plumber that proceeded to bugger the job up as the wall sleeve kit hadnt been supplied to him. so sent him on his way. was promised the sleeve kit the next day and i said my plumber could fit it to save them sending an engineer. next day no kit. add to this all the mods im having to do to pipe work to maximise efficiency and im seeing why the take up is tiny in the UK. im not naming the company as they are a recommended one and have apparently done good work else where but maybe thats in there local area. i know living in Boston creates its own issues being miles from any proper trades so if someone asked me would i recommend getting a heat pump in my area id have to say no. theres just not enough skilled trades where i live.

Im presuming you have installed the MyVaillant integration, you need the latest version

The power sensor is called [my_address]_device_0_arotherm_plus_current_power [my_address] being my actual address.

OK so the integration is installed. Good. Via a web browser is the way to access it.

If you go instead to settings - devices and services you should see a screen like this (you will have different devices and services, but should have the Vaillant one

Click on myVaillant, you should see 4-5 lines each describing a 'device', like the screen you posted above. If you click on any of them you will see loads of tiles each of which has a link 'add to dashboard', something like this

You can add tiles to the dashboard using this, then once you have done that clicking in various obvious places pulls up further options.

Hope that helps. HA does take a bit of getting used to but once you have its actually quite easy.

PS its a breeze to set up on a raspberry pi, but now you have it going on windows Id stick with it for now until you decide if you want to make it permanent!

Good start, click on add to dashboard.

Then go back to previous list from settings - devices and services and click on circuit 1 you will get some more sensors. You can repeat with the other devices until you find the sensors you want

@jamespa ive had a look at the firmware card in the add cards section and those entries are listed under attributes along with what looks like everything on the heat pump. im going to ask on the HA plugin developers site. i wonder if my firmware is too new?

I have the same firmware. I have MyVaillant version HA integration v0.9.8. The Power consumption sensor is a fairly recent addition.

What I dont understand is why you HA setup look quite different.

@jamespa going to bin this and see if i can get it working on a pi3.

dont want to spend open energy monitor levels of money but i need to see what this pump is actually doing. though i dont see why im having to figure it out when the installer should just come and balance the rads/check the commissioning, but i expect they will say it wasnt part of the quote like i had to pay my plumber to remove the old boiler and tank.

@adamk when i had my ASHP fitted by Octopus, removing old boiler and flue into roof was included in the quote, maybe it was me being fastidious about dotting is etc, wonder if anyone else had same level of service
