SONOFF TH Elite: Constant Wifi Connection Issues (THR316D)

Model: THR316D
Device ID: 1001dbe7ca
Firmware: 1.1.0 (Latest)

This has been ongoing for weeks and i’ve spent several hundred dollars on extenders/repeaters to make sure the device got a stable wifi connection. It’s located right next to a repeater, 2 other smart devices are using the same connection over the same distance without any issues. But the TH Elite consistently experiences total connection drops in the eWeLink app, only re-adding the device every 48h seems to help, but it’s a major pain.

Found a related issue, but no solution: Sonoff temperature sensor disconnection issues

Please help
