Testers? Absolutely. But not for this app I got a couple consulting projects that has pretty much delayed my progress on this. Those could use testers! It might be a month or two more.
I haven't had time to look at it, when I was looking at homebridge plugins, I saw plugins for tapping into these WirelessTags using the same API as swanny implemented. I've not played with the hubitat homebridge effort but I wonder if there is a path there...
About 75% of the swanny ST driver is related to arming and disarming motion events that are included on most of their Temp sensors and I doubt hubitat users would be doing motion sensing through a cloud service. You don't need to port the "app". The sensor related capabilities are polled, so all the event notification structure goes bye bye. As I recall, it looked pretty straight forward I'd think from a porting perspective. I'm not even sure porting is really needed. If you took the most basic hubitat driver example that polled every X seconds, you could cut and paste the swanny functions that wrap the Wireless Tag API's and the parsing. Ideally, you would add settings for polling frequency and maybe do a virtual child driver sort of structure, but to get up and running you could do driver per wirelesstag. Anywho, hopefully one of these days.
