I just came across these:
Pet Dog Anti-lost Tracker Smart Buletooth Tracer Locator Tag Alarm Tracer Finder, which would seem to be an inexpensive means of implementing presence detection, or even location detection ala iBeacon. I have not evaluated one of these myself, but I am sorely tempted to purchase one to try it out.
Does anyone have any experience with these devices? I’ll post to this thread when I’ve had a chance to play with one – already pulled the trigger on purchasing one for evaluation.
From my experience working with similar devices, I do recommend looking into reelyActive (search the forum) for the presence detection part.
Thanks for the tip,
The reelyActive project provides some very slick web views of their presence detection system in action. I’ll have to give it a go here, which probably means another rpi 3 for the experiment.
Don’t miss my tutorial on how to get it to post to MQTT for how to get reelyActive to report to OH. I can confirm it works for a Moto X PE and Fitbit. It’s a little chatty so you will probably want to add some denounce logic to smooth out the states.
This is a quick tutorial on how to integrate reelyActive's BTLE presence detection software with openHAB.
This product uses the signal strength to detect the presence or absence of BTLE devices near your sensors. They offer their own hardware devices which you can install and daisy chain throughout your structure and their software works Raspberry Pi 3. Theoretically it will work with any Linux OS that has a BTLE dongle installed and can run Node.js.
This tutorial only runs on one node. If …
I just found out that BTLE devices that look exactly the same are also on aliexpress:
here The current price is just $1.64 with free shipping to Germany in case someone else is interested.
