To me, the [ESPhome app](https://community.homey.app/t/app-pro-esphome/87271) is easier to use. You might want to check it out. ---

You have to be a bit more forthcoming if you want help, nobody here has any idea why you can’t get it working if you don’t provide more information, like the YAML file that you’re using for your ESPHome project, if you’re getting any errors, etc. ---

Most app have its own app topic here, often with manuals, howto, FAQ. These links can be found at the app page at homey.app store While I checked it already, [here you go](https://community.homey.app/t/app-pro-esphome/87271) This app developer wrote an outstanding fine manual, but take your time to read it I’d like to say. ---

i have downloaded the python and installed the esphome but do you need the home assistant app and is it possible to connect a canbus this way or not. ---

I feel that most of your questions can easily be answered by just doing a basic search with Google or [on the ESPHome website](https://esphome.io/components/canbus.html). ---

sorry but i am still new and i trie to figure it out. I have never heard of a yaml file and a command promt and i have no idea how to get a code on a esp32 using that. I have configured the esphome wizard and got it connected to the wifi. and found it on the esphome app but when i leave the esphome wizard on homey it is gone. ---
