We have been looking for a long and distant solution to be able to trigger the Aqara Hub siren from other non-Aqara sensors, whether it is homebridge, nodered, zigbee sniffer, etc. , which I can't realize for many reasons that are beyond my control and simply ridiculous. Anyway, my only option now is to follow in its footsteps [YouTube video](https://youtu.be/0_8-dEJ-WmU). However, I can't get my hands on an Aqara plug (I'm in Europe) because it's either € 50 on Amazon or anywhere else. And honestly, if I want to spend € 50 on an outlet that will remain "unused", I might as well give up Aqara and look at another option altogether. Given this, I was wondering if I could get the same results with the Aqara wireless switch (which is a stateless button in HomeKit, I think) and if so, how would I actually do it? Thanks in advance and feel free to suggest other solutions, if any. Or other options for cheap vibration / contact sensors that have a hub with a siren that can be added to the HomeKit and triggered by other sensors (I have a homebridge, so it doesn't necessarily have to be native to the HomeKit, but must have a plugin available ).
