@gunrunnerjohn posted:No offense Dave, but the simple way to do this is to monitor the power at the actual power district and control your panel light with that. No mistakes, and you can't get a false indication unless a bulb burns out.
However, a TMCC halt command, IMO, probably shouldn't turn the light off. It doesn't remove power from the track, it just stops all current TMCC/Legacy activity. However, you can immediately spin the throttle and be on the move again, so in that scenario, I feel the power district light should remain on.
None taken, but with my BP2s configured to accept accessory commands, when the TMCC1 Halt command is given, those districts all turn off. Power isn't restored until you reenable that power district (at least on my layout).
I used power district as an example. You encounter the same situation when you reset an individual engine (Numeric 0). The direction is set back to "FWD", speed is set to 0, the bell is turned off, etc.
