Update: It works! I get all notifications from my sensors and it’s working great. Thanks everyone!
For future reference, my setup:
HASS OS running on an SSD (Kingston A2000 250GB) connected to a RaspberryPi 4B 4GB
And an addendum: If anyone is having trouble migrating their Zigbee devices from Homebridge to Home Assistant, what helped me was unplugging all previous zigbee router devices before setting up the new Zigbee network, otherwise the coordinator wouldn’t start or some weird issue would pop up during setup. After disconnecting the router devices I was able to start the coordinator, and add the routers again to the new network.
There was, and then some guy put it to the test á la mythbuster style. I’ll leave the conclusion for you to enjoy
