Wyze had a conversation with the dev of the custom integration
My conversation with the people at Wyze was very productive. We are planning a way forward to continue the integration with HA while being good citizens of their platform.
Based on the information I have from this repo and the limited information they were able to share, this integration is used by between 1,000-10,000 individual HA instances. This number is increasing steadily; however, it is still a tiny fraction of the multiple millions of people who use their services. Even though we are such a small percentage of their userbase, we account for over 50% of the traffic to their servers. This amounts to a tangible cost (monetarily for Wyze) and usability effect on the rest of their users.
