I have just received the Weather Hat from Pimoroni. I have been battling to get the weather.py or any other code to run. I have started with a fresh install and tried on various Raspberry Pi 3’s. I keep getting the following error: RuntimeError: Failed to add edge detection. I am starting to think that the Hat is faulty, any help please? ---

Are you using Pi OS Lite? If so, you might need to `sudo apt install python3-pip git libatlas-base-dev` to grab the extra dependencies. (and then possibly run our installer again - I can’t remember if that was necessary) ---

Thanks. Just seems a shame that more than one person has this issue and the conversation suddenly stopped. I’ll email and post back here with what emerges. ---

So sorry that this one fell off my radar! This sounds somewhat like your error - might be worth checking that you don’t have anything else trying to use BCM 4 (or 1 wire enabled in `sudo raspi-config`)?: > > > here below errors from terminal > !\[Untitled-1\](https://github.com/pimoroni/weath…erhat-python/assets/123834271/fc4daec0-4c7a-435c-8bb1-eebd7b3d1e2a) > !\[immagine\](https://github.com/pimoroni/weatherhat-python/assets/123834271/685c4ba5-97e8-4571-9925-58a1bcc56065)
