I’m experiencing an issue with a combination of the W200s (I have two) and G400 thermostat/doorcam products. By design when the doorbell is rung three snapshots are taken and sent to the screens on the thermostats. This feature worked flawlessly after setup.
I even added a U100 and the W200s correctly shows the unlock option on the screen.
My issue began on the second day when only one of the three images displayed appeared to be a snapshot from the camera. Instead now it shows one completely black screen, one completely white screen, and then the third is the picture from the doorbell. Sometimes they are in that order, sometimes not. It’s not a complete loss of functionality by any means but it is odd and annoying.
Does anyone have any idea what might be happening here?
Additional information: All of my Aqara products have been added to Apple Home. I do record to iCloud with the G400.
I currently only have a single automation to make the W200s chime when the doorbell is rung. This wasn’t happening automatically, and i didn’t see a menu option for it so an automation seemed like an easy fix.
Thoughts?

I am having the same problem, although I only have one W200. Both the G400 and the W200 are attached to the same Wi-Fi access point, are operating on the GHz band, channel 149, and have an RSSI reading of -52dbm. Sometimes I will get one picture, a black frame, and a white frame. Sometimes I don’t get anything, and very occasionally I will get all 3 pictures. I have unlinked and relinked the doorbell to the W200 multiple times, and reset or power cycled the W200, also multiple times. The doorbell is operating off of 24V AC doorbell witing, not POE.

@klinglerjr Hey klinglerjr, thanks for chiming in with those details — it’s helpful to know this isn’t an isolated case, and your troubleshooting steps already rule out a few things.
Your setup sounds solid: same AP, 5GHz, decent RSSI at -52dBm, and hardwired power on the G400. The fact that you’re getting intermittent results — sometimes one frame, sometimes all three, sometimes nothing — plus the black/white frame artifacts, points toward a data transmission or buffering hiccup between the G400 and W200 rather than a pure connectivity drop.
A couple of things worth checking or trying:
- Wi-Fi congestion on channel 149: Even with good RSSI, 5GHz DFS/non-DFS channels can have intermittent interference. If your router allows it, try locking to a lower non-DFS channel (like 36-48) temporarily to see if behavior changes.
- Bandwidth momentarily dipping: Snapshot bursts are brief but bursty. Any QoS or airtime fairness settings on your AP that might deprioritize the doorbell or thermostat?
- W200 cache/state: Since you’ve already power cycled, maybe try leaving it unplugged for a full 2-3 minutes to clear any residual buffer state, then re-link from scratch without restoring from backup if applicable.
The black and white frames specifically feel like incomplete image buffers — either the G400 didn’t finish encoding/sending, or the W200 didn’t fully receive and decode. That it worked perfectly day one suggests either a firmware edge case or environmental variable shifted.
Since you’ve already done the standard dance and this is looking like a deeper integration bug, I’d recommend looping in support directly for escalation. Contact the Aqara Home App Customer Service Team (Profile > Help & Feedback > Customer Service) or scan the QR code:

Would be curious if anyone else with this combo has found a workaround — or if a firmware update drops that addresses it.
