The 3A controllers have a Zigbee module in them. See User manual which contains almost no information but does have a pinout.

3A12S-15 controller from "3A Smart Home GMBH Germany" https://zigbee.blakadder.com/3A_3A12S-15.html
After these get reset (like when the power supply died) they can be paired again,
- power cycle
- within 30 seconds or so go to Home Assistant to the Zigbee integration and do "add new device". It should find and pair.
