Ha ha, you got to love ST support sometimes. I know they try. Here is the response to my ticket…

As a side note: @jody.albritton and @Brad_ST have worked with me on this issue which is unrelated to the support email I received. Thanks to them!
I added Withings scale in Connect with the new integration. All my devices moved to the same room I added the scale to and the Withings scale shows up in all rooms.
This has now screwed up rooms for me across both old and new apps on all devices of course.
I am sure it is too late at this point but we can likely programmatically move devices back to their proper rooms if the devices are left in the moved state.
Based on additional investigation and user reports, this is likely not specific to meross and might impact other cloud-to-cloud (C2C) integrations.
I see you have a support ticket so I will reach out via that. As a point of clarification, renaming the devices on June 1st wasn’t the cause. The devices moved in relation to Withings which is similar to what @Nezmo reported.
That makes sense and i did add the scale a couple days before i renamed the devices. I must have missed it cause i dont use the new app very often… though I’m trying to change that. Thx for following up!
Quick update. We’ve been updated that Kasa devices are triggering this issue as well. Our development team has been updated with this info and keeps working on this issue.
