I am not inexperienced with Home Assistant but ESPhome is confusing to me. I bought this sensor from Athom with ESPhome preinstalled: https://www.athom.tech/blank-1/human-presence-sensor and connected it to my wifi. If I log into the device, it appears to be working!
The included instructions merely say “Add the device to Home Assistant” but I have no idea how? The ESPHome integration asks for the IP of a “node”.
