I was able to pick mine up locally at the 99 cent only store for $5.99 plus tax, seemed like a good deal to me.
Just picked up a few of these, I cant seem to get them to work with my Smartthings Hub. I’m looking to see if its possible? Maybe flashing a different firmware on it? I have access to solder iron, jumper cables, and I do have a USB to TTL Serial Adapter.
I have opened it up and it has a TYWE3S label inside on one of the chips. Any help greatly appreciated. Thanks.
