Hi everyone, Pardon me for potentially very stupid questions, I’m planning on buying homey pro since we just bought our first house (hurray) so I’m a massive newbie that is trying to understand possibilities and limitations. I’m reading a lot on detected occupancy but I’m mostly concerned about toilet occupancy since I want to automate the lights there, I’ve come up with the following very simple automation flow and I was wondering if this is doable in homey out of the box (also thought on whether this would/could work \> off course its going to be a issue if someone closes the door but I could create a side step to check for door open stage for a long time if: door closed and if: motion detected within 0.1 to 2s after door closed set occupied: true elif: door closed and if: no motion detected within 0.1 to 2s after door closed set occupied: false elif door open \> 180s: set occupied: false Also a friend keeps trying to push me to node red because you can do all kings of crazy stuff in there, however I really like all the build in communication protocols (which will work nicely with my new somfy RTC blinds), can you still use other HA platforms such as node red in conjunction with Homey or are you tight to what homey offers and thats it? ---

You’ll need multiple flows and timers (separate app), but I would say that’s doable. About Node Red, you can communicate via MQTT with Node Red and use that alongside or in conjunction with Homey. Search for MQTT and the MQTT Hub app and read all about it. ---

Why the whoops? It’s that when you do a number 2 and end up in darkness. ---

Thanks, anything particular I need to take in to account, you mention the timers is a seperate app, and you would recommend, just a quick browse already shows 4 of them. ---

But not quite right yet, and I can’t get my head around it. You can view it if you like, by hitting the red pencil icon on my post > [@JohninNL](#): > > timers I use Chronograph and happy with it.
