The problem
Since I did update to HA 2026.3.4 I get often the below error message
Unable to contact the vendor's server.
Check your network and review the vendor's status page, https://status.resideo.com.
When I check the resido status page there are no outage reports, my evohome system is connected to internet, and I also can access my evohome system through the honeywell app. So it seems very unlikely that there is a problem with accessing the vendor's server
