Wyze lock gateway replacement

Mine started going offline every few hours then recovering. No repairs & can’t buy just the gateway. Support response:

“As of this time, Wyze also does not have a technician that can make repairs to our products.”
“All we can do is to perform the troubleshooting. But for technicians who can repair the devices, is currently not available. I will forward this concern to my team so that we can make this kind of option available in the future.”
