I see this in Upstart and you can change the setting when doing a communications test maybe?
Using the option to change whether I use the repeater or not didn't change the signal strength doing communications a communications test with one appliance switch in the attic.
Trying an older PCS ((WS1D) Wall Switch - Standard Dimmer)1000 watt switch (Chandelier) next.
playing with some switches. I have SA, HAI and PCS switches in place. I do not see any noise so far on any switches here.
1 - no repeater - device is set to direct packet and uni-packet - communications test shows - 33 / 63
2 - repeater enabled - direct packet and uni-packet - communications test shows - 70 / 117
3 - repeater enabled - link packet and multipacket-2 packet - communications test shows - 66 / 114
4 - repeater enabled - direct packet and uni-multipacket - 2 packet - communications test shows - 64 / 112
Testing another switch now - HAI 55A00-1 1000W Dimming Switch
1 - no repeater - device is set to direct packet and uni-packet - communications test shows - 40 / 66
2 - repeater enabled - direct packet and uni-packet - communications test shows - 87 / 114
3 - repeater enabled - link packet and multipacket-2 packet - communications test shows - 82 / 111
4 - repeater enabled - direct packet and uni-multipacket - 2 packet - communications test shows - 81 / 110
Looking for an older switch now...found a 59A00-1 300W Lamp Module ...higher signal levels than above with and without repeater.
Found a old one marketed OEM and its just labeled Lamp Module (UML-E) firmware version 04.18
Playing with car today (replacing an FSU - Hedgehog) - what a PITA it is to do this....be back...
