I’ve been trying to pair 4 x Zemismart ZM25EL motors directly to an Amazon Echo Show 8 (3rd gen, built-in Zigbee hub) via the Alexa app, without a Tuya/Zemismart gateway.
What works:
- Motors pair fine to the ZC175A-9 9-channel RF remote using: long press Set button until beep → press top-right button on remote → confirmed with beep
- Motors respond correctly to remote up/down/stop commands
What doesn’t work:
- Alexa app → Devices → Add Device → Other → Zigbee → Discover
- I press Set button 3 times (tried both quick and slow with pauses between each press per Mr.ToR’s guide)
- Motor beeps and blue LED flashes 3 times then stops completely
- Echo Show 8 never discovers the motor despite searching for 60+ seconds
Key observation: On the new ZM25EL hardware revision, the motor never physically jogs — it only beeps. The “short up-and-down movement” described in Mr.ToR’s excellent guide doesn’t happen. I suspect the pairing window on the new hardware is extremely short — maybe 5 seconds — which isn’t long enough for the Echo Show 8 to complete the handshake.
My questions:
- Has anyone successfully paired a ZM25EL directly to an Echo Show 8 Zigbee hub?
- Is the very short pairing window (3 blinks then off) a known issue with newer hardware revisions?
- Is there any way to extend the Zigbee pairing window on these motors?
- Or is the ZM25EL effectively locked to Tuya’s own Zigbee hub implementation?
Happy to share more details. Thanks in advance.
