FWIW, I just ran into the very same issue with the same light switch from Enbrighten, also using ZHA. I swapped out the ZigBee coordinator from the Popp ZB Shield (Raspberry Pi) to the SONOFF Zigbee 3.0 USB Dongle Plus, and things started working immediately. I didn’t (yet) change the firmware on the dongle, still researching if that is necessary for my situation.
