Failed to perform the action: climate/set_fan_mode: NotImplementedError

[shagadeli]

I've a Siber DF Evo 4 with a physical remote control and the ESP32 Ramses board from Indalo-Tech. I can see every available sensor value and I get 3 devices on the integration, the Gateway, the remote and a FAN device.
Everything appear to work as intended except the send command. Whenever I try to send a command I get an unknown error.

My known list:

"18:100900":
  class: HGI
"32:162627":
  class: FAN
  _note: SIBER DF EVO4
"37:143839":
  class: REM
  _note: SIBER DF EVO4 Multicontrol DFEVOCTRL08
  commands:

    bypass_auto: " W --- 37:143839 32:162627--:------ 22F7 003 00FFEF"
    calendar_off: " W --- 37:143839 32:162627--:------ 22B0 002 0006"
    calendar_on: " W --- 37:143839 32:162627--:------ 22B0 002 0005"`

And this is the error in the log when I try to send any command:

NotImplementedError

I tried to send the command via the FAN entity and via actions (services), with the same result. I managed to call the learn a command service sucessfully, but when trying to send the command I always get the same error:

Failed to perform the action climate/set_hvac_mode. unknown error

or

Failed to perform the action ramses_cc.send_command. Unknown error
if sent directly from actions

I run my HA in HAOS installed directly on an Intel NUC.

The trace log you've provided is not for a send_command, it's for a service call (probably via the UI).

This service call is not implemented - a PR would be considered.

You should be able to use a custom command instead - submit another issue if that does not work as expected (you may need to ask for help on the user forums).

Thanks for your reply.
I did again on the Developer tools > Actions > RAMSES RF: Send a Remote command

I get : Failed to perform the action ramses_cc.send_command. Unknown error
