(Hello, first of all I wanted to thank you for this fantastic work. I have flashed the WiFi device with ESPHome. But I am unable to flash my .yaml below. I get the folloiwng error:)

(If you could please help me fix it. I'm sure it is something simple that I am missing.)

Could you please use code block (triple backticks) to format your comment, as it's difficult to read? As far as I understand you have created the copy of dtu-wbs1-v001-48v-example.yaml and changed inverter_maximum_power parameter? Try clearing .esphome folder.

Hi

Thanks for your reply. I have edited my post above hopefully it is easier to read. I am trying to use a copy of dtu-wbs1-v001-24v-example.yaml. I will lookup how to clear the .esphome folder.

Thanks
