How good is the app support for your heat pump?

Steelbadger · 2025-10-15T08:51:15Z

I've not been on here long, but one recurring theme seems to be that the apps are often a bit bare bones, and that the energy monitoring information is either limited or untrustworthy. It would be interesting to hear from the owners of different heat pumps about the app support (if it even exists). I have obviously heard about the seeming inaccuracy of the Daikin app's monitoring, and I've also heard a few complaints about the Vaillant app, too, but it would be great to get some more info on what all the different apps actually do. Our Bosch 5800i 5kW has a ConnectKey installed which, in addition to giving Bosch remote access if needed, allows us to access it using 'HomeCom Easy' which gives the following information and controls: At a glance see the hot water and controller room temperature as well as local weather. Access more detailed data like flow-return temperatures, compressor modulation, start-stops and operation hours. See the daily, monthly, and yearly energy consumption and generation. Data resolution is 0.1kWh with round-to-nearest, but the graph seems to use higher resolution data when it's being built. See hourly data for the last three days, daily data for the last three months, and monthly data for the last three years. This shows consumption/generation, as well as flow/water/room/outdoor temperature, split between central heating, hot water, and cooling. I get push notifications for any errors or warnings thrown up by the unit. I can see and modify the schedule for both hot water and central heating target temperatures. I can set the quiet mode level (limit maximum compressor power). I can tell the heat pump I'm away (to turn it to frost protect), and I can schedule up to 8 upcoming holidays which will automatically start/stop the heat pump's holiday mode. I can also export the energy monitoring data to a CSV file, but it's still limited to a precision of 0.1. In general, I find the app okay. It's pretty slow, and it's either not caching any of the energy monitoring data, or it's just really, really slow. Allowing remote access to an engineer is a nice QoL thing to have, and the holiday programming is really nice. I'd love to have access to the full data resolution rather than the rounded numbers as I'm a mathsy guy. I'd also like to have some kind of connection to Home Assistant or other smart home system. Overall, not bad. The engineer in me wants more data, of course, but the control options are fairly good for a typical home owner. Then again, I don't necessarily know what I don't have. So it's show and tell time. What does your app look like? How well does it work? What can you do with it, and what do you think is missing?

I have bluetooth dongles on my HA, but the signal from the BMS does not reach it.

This is ambiguous; please clarify.

The Bluetooth signal does not reach due to the distance...

As I already have three integration adapters pointing at my Solis inverter, am I dreaming that info could be set to "flow" from the modbus of the battery via the Solis?

1: Please define what you mean by "integration adapters".

From what source have you picked up that term?

Greg Hohpe's Enterprise Integration Patterns I have to admit, I never got to write mine!

These terms have never really been fully standardised. But by 'an adapter', I mean the bit of code that allows data to flow from source and destination interfaces.

When that is installed and configured in a processing unit (in this case, what runs home assistant), then I would name it an integration.

Is it perhaps a poor translation from Mandarin?

😊 Where do you get these ideas?

Hopefully Mandarin picked it from Hohpe's, who was/is the western world's authority for many of these things!

Now seriously, these are implementation specific details for monitoring...

The most important for readers is to get heating system to perform well and not cost an arm and a leg to run.

The topic in the subject shows that many people wonder why the controls and apps were either not setup/explained or not fit for purpose.

You and I know that, for the owners to have this, these "integrations" need to be configured and a few other 'boxes' are often needed.
