Ability to connect 1+ devices

[Trteich]

Hi, thank you very much for your work, it is exactly what I was searching for. Is there ability to connect more than 1 prana recuperator? If yes, how config file should look like?

Hi. More devices can make esphome very unstable, but if you are ready to test i can try to make it possible later. For now i prefer one recuperator per esp32 for easier troubleshooting, also i have only one recuperator so i cannot test multiple devices by myself

I've already dealed with it. Works perfect. As mentioned on ESPHome web site, esp32 can serve up to 3 devices without issues. If there is need, I can share config

Ok, try it:

ble_client:
  - mac_address: 00:A0:50:00:00:03
    id: prana
  - mac_address: FF:FF:FF:FF:FF:FF
    id: prana2

prana_ble:
  - id: prana_client
    ble_client_id: prana

  - id: prana_client2
    ble_client_id: prana2

sensor:
  - platform: prana_ble
    prana_ble_id: prana_client
    voltage:
      name: "Prana voltage"
    frequency:
      name: "Prana frequency"

  - platform: prana_ble
    prana_ble_id: prana_client2
    voltage:
      name: "Prana2 voltage"
    frequency:
      name: "Prana2 frequency"

here is my config which works with 2 devices
