Prana Recuperator support

[VladNord]

Describe the problem you have/What new integration you would like

Add Prana recuperator control over Bluetooth. Devices supports control via a regular IR remote control and via bluetooth using a smartphone application

Please describe your use case for this integration and alternatives you've tried:

On github found two integrations for these devices, but the main problem is that the controller (raspberry) must be located near the recuperator itself, which is impractically. this https://github.com/alextud/ha-prana and this https://github.com/corvis/prana_rc

In second case it can be installed to another linux machine with bluetooth and connect it over the network to HA, but this is also not practical

Additional context

Thanks in advance, I think this integration will be useful to the community.

this integration would be amazing! of the two projects mentioned above, I could only get it working with the one made by @alextud but for some reason it is very unstable. I run humeassistant in a vm on a server located in the attic. I have a bluetooth dongle that is passedthrough to the VM and use that to connect to the PRANA machine. For some reason the connection just drops randomly. It could be the distance between the machines. An ESP32 is much easier to bring closer.

Would be very nice to have this feature!

My friend and I are working on "integration" for ESPHome which involves changing the ESP32 to another one, flashed with ESPHome and full configuration for Prana to work locally.

This is very interesting: if you need a tester, I'm available to use your component. I got two recent units: Prana 210C ErP Pro and Prana 160 ErP Pro (2022 models with Bluetooth and WiFi).

Interesting too. Do you mean replacing the built-in chip with another one with ESPHOME firmware?

Yes, desolder the ESP32 that's on it and solder another ESP32 which then gets flashed with ESPHome.

Nice. Hardcore DYI, i like it ;)

I have Pranas 150 (2020-2021 year), and it has only BT without wifi. It uses ESP32 or another controller?

I don't know, open it up and show us. 😁

Oh... I didn't catch your idea to locally manage the VMC unit... it is quite invasive... :-)

I was supposing you were using an esphome component to simulate a bluetooth controller. Such approach, for example, is use the Daikin Madoka controller that was recently submitted for inclusion (https://github.com/esphome/esphome/pull/5951). I'm using it with profits.

OK, we need a list of devices having ESP32 inside

Definitely Prana 150 Apr2020 revision doesnt (I suspect that all devices which do not support Wi-Fi too)

Add to the incompatible list :)
