Integration checklist

1
Commission gateway
required
App: Gateway
RS485 TO ETH (B) at 192.168.1.254:4196 (rtuovertcp). Serial side matches the RTU bus. HA OS VM must reach this IP.
2
Name & enable zones
required
App: Overview
Overview: set zone labels. Leave Zone 6 free if BAS-153 owns heat-call dual relays.
3
Deploy Modbus package
required
App: HA Config
HA Config / this hub exports hub + switches + sensors. File: packages/borealis_taco_zvc_modbus.yaml
4
Enable packages in configuration.yaml
required
homeassistant.packages: !include_dir_named packages
5
ESP32 sensors (radiant mix)
recommended
App: Radiant Mix
ODR / IDR / MIX entities online before BAS-153 / BAS-356 package.
6
Optional zone climates
recommended
App: Climate
generic_thermostat heat-only entities. Map target_sensor to real room temps.
7
Optional safety automations
recommended
App: Home Assistant
Long heat call, gateway offline, end-switch faults, priority log, away setback.
8
Check config & restart
required
Developer tools → Check configuration → Restart. Smoke-test one zone switch.
