nearer the coordinator, twice for the far one.
Heh, there’s the special case of the kitchen ones. My kitchen is some kind of pseudo-Faraday cage. Wi-Fi gets blocked almost completely (I have a cabled repeater in the kitchen just for reliable Wi-Fi in there …), Zigbee does slightly better (probably because there’s a Zigbee light just outside the kitchen, but it depends on the position, so my first few tries seemed to work without an issue, but the battery just dropped, after 1 year it went through two batteries. I found a different spot for it, and now it works normally :D
edit: I should also mention that I have 2 ZigBee routers in the kitchen, which seem to just work normally. I honestly just gave up wondering about WTF my kitchen does to signals.
Alexa? :D
