The Viessmann E3 CAN bus is read by vitocal-can, an ESP32 gateway (open3e-esp32)
at the Vitocal's external CAN port, which publishes open3e/# directly to the
cluster broker (S28-28). edge-1 must no longer read the bus: a second UDS
client on the bus disturbs the gateway's requests.
- remove the roles heating-can and socketcan, the play
install-heating-can.yml, its site.yml import and the inventory group
heating_can; edge-1 stays in edge_host through zwave_gateway
- install-edge-host.yml pre_tasks: compose down (containers and image) and
remove /opt/edge-host/heating-can, remove 80-can0.network and reload
networkd, take can0 down; each step is a no-op where it is already absent
- group_vars edge_host: drop edge_open3e_mqtt_topic, used only by heating-can
- docs: edge-host.md and the ISO README no longer list the CAN stack
