Document the ThirdReality Smart Button (3RSB22BZ) pairing mode quirk that bit us today: the button has Standard ZigBee (blue only) and Echo ZigBee (blue + red) modes, and only the former works with zigbee2mqtt. Switching requires 5 quick presses of the back reset button (firmware >= 1.00.22), NOT holding the front button. Also document the Smart Plug Zigbee PROD pairing procedure and the BLE->ZigBee mode switch.

Zigbee device notes
Per-device quirks discovered during setup. Keep this file in sync as we encounter new devices.
ThirdReality Smart Button (3RSB22BZ) — Door Button
Has two pairing modes — the button will only work with zigbee2mqtt in Standard ZigBee mode.
| Mode | LED indicator | zigbee2mqtt compatible? |
|---|---|---|
| Standard ZigBee | blinks blue only | yes |
| Echo ZigBee | blinks blue + red alternating | no |
Switching modes depends on firmware version:
- Firmware ≥ 1.00.22 (most common): press the back reset button (pinhole) 5 times within 5 seconds.
- Firmware < 1.00.22: hold the front button + back reset button simultaneously for 5 seconds.
The front button does NOT trigger a reset — only the back pinhole does.
Holding the front button for any length of time only emits Zigbee
action events (single, hold, release).
If the button joins but zigbee2mqtt can't interview it correctly, check the LED — it's almost certainly in Echo mode.
ThirdReality Smart Plug Zigbee PROD (3RSP02028BZ / similar)
Factory reset / pairing mode: **press and hold the side button for
10 seconds** until the LED flashes (red = ZigBee mode, green = BLE mode).
Most plugs ship in BLE mode out of the box. To switch to ZigBee: hold button + insert into outlet + hold 10s + release + press button twice immediately. LED should flash red (ZigBee).
To re-join an existing ZigBee network (e.g. after the dongle was swapped), power-cycle is usually sufficient — no reset needed. The plug retains the network_key and rejoins automatically when permit_join is open on the coordinator.
