Sure, Raspberry Pi 3B+ running Raspian 10, no open updates according to apt-get. Conbee II with latest firmware (26780700). Network consist of 73 nodes, mostly Aqara sensors and Ikea lights, some Osram/Lightify lights, a few sonoff relays, a few sunricher switches…
Besides a piVCCU and zigbee2mqtt instance the Raspi isn’t doing anything besides being a Smart Home Gateway.
