Glad to hear that the app is working out for you The IR-module that you are mentioning is actually not present in the underlying library that I’ve based this on at all (smart-bus/commands.js at master · caligo-mentis/smart-bus · GitHub) so that request would take a lot of work in the library before I could implement it in the app.
No turning off the 8-in-1 sensor either, but you could move the logic away from the sensor or the logic controller and over to Homey, and then just disregard any movement if some other state is set (like time of day or another sensor).
About the Universal switches: That part is pretty tricky, as nothing particular in the bus is responsible for keeping the state of universal switches. The implementation today is based on Homey listing to the bus for Universal Switch changes (so your example is correct), and it can also send back out, but to no-one in particular. I’ve considered adding the possibility to set the address of a logic-controller in the apps setting, and then send all Universal Switches to that. If that was the case, I guess you could switch to night mode. The question is though: Do you want HDL to have a night mode, or Homey? I’m leaning in the direction of leaving the logic part to Homey.
