I have made it: Getting FHEM and Homebridge running on Fujitsu F-Cue board. The board itself provides via WLAN and hostapd a mobile hotspot where a smart phone can connect to. On-board Bluetooth connects peripherals like FEEU ClickBeetle (www.feeu.com/clickbeetle). See some short demo video controlling some LEDs and a wireless connected ClickBeetle.
