I’ve been diving into the world of smart home automation lately, and I must say, it’s been an exciting journey! I’m currently working on setting up a system where my Home Assistant (HA) can monitor the room temperature using a Broadlink sensor and adjust my AC and fan accordingly. The goal is to turn off the AC and turn on the fan if the temperature drops below a certain threshold. I’ve managed to get the actions to work, but I’m stuck on using the Broadlink sensor as the trigger. I tried removing the Broadlink sensor and using a Shelly light instead, and that worked perfectly with brightness as the attribute. However, when I switch back to the Broadlink sensor, I don’t see a similar attribute to use. I’ve been looking through the settings, but it only lists “state class,” “device class,” and “friendly name” besides the “unit of measurement” I’ve chosen. I’m not sure what I’m missing here. Maybe someone with more experience could shed some light on this? 
On another note, I’ve also been exploring Z-Wave sensors. I came across a thread about finding a Z-Wave pressure gauge sensor to replace the basic analog gauge on a Hayward filter. I’m curious if anyone has found a ready-made solution for this or if they’ve had success with DIY projects. I’d love to hear about any experiences or recommendations! 
Lastly, I stumbled upon a discussion about the documentation for S_XXX.xml files. It seems there’s some confusion about the purpose of certain attributes like “sendEvents” and “relatedStateVariable.” I’m not entirely sure how these settings affect the overall functionality, especially regarding event processing and static JSON files. If anyone has a deeper understanding or can provide some clarity, I’d be grateful! 
Overall, it’s amazing how much potential there is with these smart devices, but sometimes the learning curve can be a bit steep. I’m looking forward to hearing from the community and learning more about these fascinating technologies!
