Air Source Heat Pump Energy Produced exposure via API? #175

Description

@domharrington

Hey! I've been using this module (via the homeassistant plugin) to view the status and data from my air source heat pump. I'm looking to calculate the COP of my heat pump and for that I need two pieces of data:

  • energy used (kWh)
  • energy produced (kWh)

The former is provided and surfaced in homeassistant:

But the latter does not appear to be surfaced. It is exposed in the Ariston Web UI and the control panel screen I have in my house (but not in the app, for some reason).

Image

The API that the web UI accesses has this URL: https://www.ariston-net.remotethermo.com/R2/PlantMetering/GetData/xxxxxxxx

The data in the response looks like this:

Have you seen this before? Is this some web-specific API? Do you know if this is returned via the HTTP API and can it be accessed via this module and surfaced in Homeassistant to calculate COP?

Also this is a bit of a nit, but my heat pump comes up as a GALEVO device type which is not accurate:

It is one of these Nimbus units: https://www.ariston.com/en-uk/products/heat-pumps/air-source-heat-pumps/nimbus-plus-m-net-r32/

I'm very happy to help with implementing this, if you can point me in the right direction! Or I can share responses and HAR files if it helps with reverse engineering anything.

Thanks in advance.
