@TonyApuzzo one thing to note is that the OpenEVSE team is considering deprecating RAPI over MQTT.

IMPORTANT: It is no longer recommended to use RAPI API if EVSE also had a WiFi module fitted, since use of the RAPI API will conflict with the WiFi module, instead the HTTP API should be used to control the WiFi module instead of the controller via RAPI.

User RAPI will be removed in a future version of the firmware or at least limited to $Gx commands

@ruimarinho thank you for the warning, but it doesn't seem that the HTTP API is available for the legacy ESP8266 WiFi module, only with the newer v4 ESP32 gateway. I'm personally not going to upgrade either the base firmware nor the WiFi module any time soon based on my usage.

Hi, it seems the usage of the MQTT platform will change soon. I have some warnings :

Manually configured MQTT sensor(s) found under platform key sensor.

Please move the configuration to the mqtt integration key and restart Home Assistant to fix this issue. See the documentation, for more information.

Have you already fixed it ?

@quentindavid I am not using the OpenEVSE charger any more, so I can't test any changes, but I made the change based on documentation and verified that it loads without errors or warnings in HASS.

Let me know if it works or not.

Hi @TonyApuzzo ! Thanks a lot for the refactoring :) It seems to work except this warning

Manually configured MQTT number(s) found under platform key number.

Please move the configuration to the mqtt integration key and restart Home Assistant to fix this issue. See the [documentation](https://www.home-assistant.io/integrations/number.mqtt/#new_format), for more information.

I still need to dig a little to be sure everything is running fine except that.

Ah yeah, I should've checked the other platforms. It seems that number is the only other one I use that's changing, so I updated that one too.

Yeah it seems to have done the trick. Thanks a lot @TonyApuzzo !!
