I know that I should just put together a test setup and confirm all of my assumptions, but I figured I would get other people's experieces first.

I want to know if I put an LED on a track bumper that I could use to indicate whether the track is powered or not (I plan to use an MQTT controlled relay to turn yard tracks on and off) will the LED trip the detection circuit of the DR4088CS?

I am also concerned about the MQTT relays, but my assumption is they are just a closed or open circuit and should not change the resistance of the circuit.

Oh yes it will, bad idea...?

?

But what the heck is a MQTT relay and what for it's used ? Shutting down power on track segments is very "analog" ?

Bummer on the LED, I was hoping to add that indicator of track power on the bumpers.

As for the relays, yes, I want to be able to kill track power on areas with locomotive storage. Do you have a better solution for this?

Thanks

With regard to cutting track power to sections of track you could use a latching/bi-stable relay controlled by a switch controller (DR4018 or spare switch in DR4024). You could even use a DR4102 as the relay, just wired to one side which would give you four controllable sections.?

Cutting track power on a DCC layout may seem a little analog but it is an easy way of isolating tracks in storage areas. I’m thinking of storing some lighted coaches so the lights go off when not in use (cheaper than installing decoders in them) and you can still use the DCC system to switch the track sections on and off.?
