Thanks, I was definitely confused! It does sound like the effort to run a MQTT server isn’t really worth it for one button. However, I don’t really know a good way to build a good zigbee network. My house has in-build LED lights, I can’t swap them for Hue bulbs or anything like that. The only other common extender I know of is smart plugs, and having a bunch of smart plugs all around the house that aren’t actually used is just annoying.
I’m not sure the effort is worth it for this one button at the moment. Maybe I will wait until I’ve added other things naturally extending the zigbee network.
