I build in a DC relais and connected it to the BlueHorse Board. I also replaced the original LGB smoke generator. Not it is possible to switch the new smoke generator on/off by using the BlueRail app over BlueTooth and the personal smartphone.
To avoid killing the smoke generator by running it dry, I also added a 3mm LED to be able to see, if the smoke generator is turned on.
Enjoy some of the impressions….
