Apologies if this is obvious, but I am a newbie.

I have two FoxESS inverters and M trying to setup Home Assistant. The FoxESS HA integration requires me to add the inverter serial ID, serial number and API for each inverter.

This works well for 1 inverter but not the other. I can access 1 API from the user details but I don't know whether the API references me (i.e. I only need 1 API) or whether it references each inverter and so I need 2 - in which case I cannot see how to obtain the second API.

Can anyone help me please?

Are both inverters in the same account - if they are when you go to the api management screen on the website you should see it say Number of Api Calls 2880 - if it says 1440 then you must have 2 separate accounts which would need 2 api_keys (and you would have 2 usernames to log into the fox cloud)

If it is 2880 then you use the same api_key for both inverters and set the DeviceSN to each inverters device serial number

Code: Select all

sensor:
  - platform: foxess
    name: Fox1
    deviceID: enter_your_inverter_serial_number_1
    deviceSN: enter_your_inverter_serial_number_1
    apiKey: enter_your_personal_api_key_1
  - platform: foxess
    name: Fox2
    deviceID: enter_your_inverter_serial_number_2
    deviceSN: enter_your_inverter_serial_number_2
    apiKey: enter_your_personal_api_key_1

If it is individual accounts you will need 2 api_keys

Code: Select all

sensor:
  - platform: foxess
    name: Fox1
    deviceID: enter_your_inverter_serial_number_1
    deviceSN: enter_your_inverter_serial_number_1
    apiKey: enter_your_personal_api_key_1
  - platform: foxess
    name: Fox2
    deviceID: enter_your_inverter_serial_number_2
    deviceSN: enter_your_inverter_serial_number_2
    apiKey: enter_your_personal_api_key_2
