I've been using a single outlet in each room - sure I have repeaters that came after the fact but no troubles!
Seedan, CMars, DoGain - all are based on the same chips - show up as eWeLink- zig 3.0 and solid as stone. I turned off Zwave a long time ago - don't use BT or Wifi either. Helps that I modded the driver from markus to my needs
