I guess I just want to say that with 1.45 my switches set at 99% (nothing set for max value in settings) and disable local control enabled, I get a clean 124V in and 124V out, and my zigbee bulbs run happily using solely scene control via ABC Manager.
Not sure how/why/what is up here, but you should be able to replicate my setup without issue.
- Confirm settings for max value is 99 or default.
- Enable remote control so you actually can control the dimmer level temporarily.
- Dim up to 99%
- Make sure no automations or whatever are controlling the level of the switch. Hide from interfaces so it just lives at 99% forever.
That Should get you what you are looking for.
