Interesting. They seem to warn against using the server for much as it's resource hungry and potentially unreliable, but that appears to be focused on the task of serving data; a simple webhook type use should be safer. It'd be pretty amazing if ESPHome supported something like ZeroMQ[0], so you could talk between nodes in anything up-to full-mesh at a socket-level and not need to worry about the availability of a server to manage the traffic.
