Can any one offer me any logic as to why I may be having this issue with one of two Matter shades dropping the network connection and going offline during the evening hours? This has happened for three consecutive evenings since I installed the two SmartWings Matter shades Friday evening.

Background:
I recently received two SmartWings Nowa Cellular smart shades with “Matter over Thread” motors. I set them up with the Aeotec hub and they were easily paired. This was accomplished on Friday evening. Since the installation I have had one of the two shades go off-line every evening for the past three evenings.

So to reiterate, both shades remain online throughout the daytime. However, sometime during the evening hours, one of the two shades go off-line. The first two evenings it was “Bedroom Shade 1” that went off-line. Last evening “Bedroom Shade 2” went off-line, (see attached pictures).

To reconnect the offline shade, each morning I deleted the offending shade from “Matter Accessories” under iPhone settings and then deleted and reinstall the offending shade to the SmartThings app. When reaching out to SmartWings, their R&D group recommended that I just reboot the motor to bring the shade back online and they provided instructions for rebooting the shade motor. When following these instructions this morning I was successful in bringing “Bedroom Shade 2” back online. However, based on the shades connection history, I suspect the one of the two blinds will go off line again this evening.

SmartWings discussed sending a “controller for replacement” if the problem persists, however I do not believe that it is a controller issue because “Bedroom Shade 1” went off line the first two evenings and last night it was “Bedroom Shade 2” that went offline. I would suspect that this problem was related to the controller if the issue was specific to only one of the two shades.

I have asked the SmartWings R&D team to test two shades in close proximity. I get the notion that if I had only one shade connected I would have no issue. It appears to be an issue having to shades on the same network. It appears that one or the other drops a connection during the evening hours. I know this doesn’t make sense but it’s happened repeatedly, as mentioned, for three consecutive evenings.

I have the two matter shades paired with my Aeotec hub. The shades are connected with the “Matter Window Covering” driver. As mentioned above, I am using the iOS version of the SmartThings app. Here are the two connected blinds displaying in under the “Matter Accessories” under the iPhone settings. They are display as connected to (SmartThings Hub 75F5) as SmartThings Window coverings. I’m not sure why there is no “Serial Number” displaying in the “Connected Services” screen, or if this is even necessary.

Any insights anyone may be able to provide on this issue will be greatly appreciated.

I don’t know about your household, but in many homes there’s a lot more Wi-Fi activity in the evening than there is during the day because of people watching streaming or playing video games. Or just having more people home at the same time. But it’s the big video streams that tend to cause the most trouble.

Just like zigbee, Thread is on the same frequency as Wi-Fi, but is a much lower powered protocol, so Wi-Fi can often drown it out.

That’s not necessarily what’s going on with your system, but I just wanted to mention it as it’s a frequent cause of timebased local interference. :thinking:

I’ve mentioned before in the forum that I used to have some problems with my Zigbee devices every weekday afternoon around 330 when my neighbors’ teenager got home from school and started playing video games on superboosted Wi-Fi. :video_game:

We do stream in the evening. My wife steams programming on TV and I sometime game. I don’t believe this activity is a contributing factor and both the TV and my PC are connected to the router via Ethernet cable. Your insights are appreciated as always JDRoberts.

If they’re ethernet, not Wi-Fi, then that’s not the issue unless it’s a neighbor’s Wi-Fi like it was in my case.

I didn’t think it was that likely, but I did want to mention it as it is a common culprit in time based interference.
