Hi all,
Do any of you know the possibilities to use an Ultra-Wideband sensor with Homey?
Use case:
I would like to have Homey to trigger actions when I (or better: my phone (Samsung S24+) without getting it out of my pocket) approach my homedoor, but with more accuracy than with (i.e.) WiFi of Bluetooth. For example open my door, turn on the lamp in the hallway, etc.
I have an apartment and entering at ground level might now trigger such actions too. I would like to have these actions only triggered when arriving before my homedoor at the 2nd floor.
As the Aliro (also UWB) standard hasn’t arrived for my Nuki setup, I thought I could achieve the same with a separate UWB sensor and Homey as well.
Other thoughts to achieve the above are welcome too of course! 
Maybe you can determine a Bluetooth beacon/tag location with ESP32’s in multiple rooms by determining the signal strength from the beacon to each ESP32?
Interesting, sounds like a nice “hobbyproject”! 
But totally no experience with ESP32’s. Any remarks or links on how this would work?
And would I need multiple ESP32’s when I only want to use it for determining the distance from my phone to the front door? And without getting my phone from my pocket?
(Perhaps wasn’t clear that I would like to use my phone as a trigger, without getting it out of my pocket. Added that in my post above).
It depends on what phone you have. Samsung, Apple and Xiaomi don’t advertise to other Bluetooth devices AFAIK. Realme, OPPO, OnePlus and some Huawei phones do advertise to other devices. Your phone needs to advertise its presence to other devices, because that’s the only way it can get discovered by the ESP32’s.
Thanks @smarthomesven. I have a Samsung S24+ (also added above), so then a ESP32 solution would not be possible I get from your reply.
Perhaps back to a UWB sensor solution then; if possible?
