Wyze Lock gateway died

After 14 months of use, my Wyze Lock gateway died. I tried all the recommended troubleshooting and contacted support online and over the phone, but nothing worked. Wyze told me the gateway is out of warranty, and I don’t qualify for a replacement. I don’t mind buying a new gateway. However, the parts replacement kit is out of stock, and there is no information on when it will be in stock. Given Wyze’s history of out-of-stock items, I am asking if anyone knows where I might be able to find or purchase a gateway. As of now, my lock is useless. Thanks!
