Impossible to connect to the heatPump

[yann500]

On MQTT Explorer, my heat pump work perfectly:
192.168.0.34
heatpump = {"power":"ON","mode":"HEAT","temperature":22,"fan":"AUTO","vane":"SWING","wideVane":"|"}
status = {"roomTemperature":21,"operating":true}
timers = {"mode":"NONE","onMins":0,"onRemainMins":0,"offMins":0,"offRemainMins":0}
debug =

But after compiling of ESPhome config, I can't connect to ESP.
======================== [SUCCESS] Took 1118.87 seconds ========================

ERROR Error resolving IP address: Error resolving address with mDNS: Did not respond. Maybe the device is offline., [Errno -5] No address associated with hostname

Thanks in advance for your help.

This would appear to have nothing to do with this project/code, this is ESPHome not finding your ESP on the network: check out https://esphome.io/components/wifi.html and look at the use_address option.

Thanks for your help, but I didn't see this option in your YAML example. Why my esphome has to specific configuration ?
