Details 
vitocal-can is a Waveshare ESP32-S3-RS485-CAN running boonkerz/open3e-esp32 on the
Vitocal 250-A's external CAN port. It takes over the open3e/# topics from
the heating-can stack on edge-1 (S28-28).

The controller pushes the password through the firmware's PUT /api/settings
over plain HTTP. The firmware sends its compiled-in DHCP hostname, so the
device is reachable as open3e.iot.renner.uno regardless of its configured
hostname. The controller egress gains that FQDN on port 80.
