| Armstrong Air Comfort Sync A3 (Lennox S30) | Partly works | Reads work; setpoint writes from Home mostly lostSaved copyPatch with suggested fixes: homebridge-lennox-setpoints.patch Test Scenario Plugin: homebridge-lennox 0.1.2 / lennoxapi 0.1.2 Thermostat: Armstrong Air Comfort Sync A3 (rebadged Lennox S30, reports `productType: S30`), firmware 3.95.146, local connection Homebridge: child bridge, Node 22 Reading state works perfectly.

| Lennox S40/S30 remote room sensors | Requested | Secondary room sensors not exposedSaved copyFirst off, thank you for building this and the underlying lennoxapi TypeScript library. Having local LAN control that bypasses the Lennox cloud is incredible. Currently, the plugin successfully pulls in the primary zones and maps them to HomeKit, but it does not expose the secondary/remote room sensors connected to the system. Since this API is a TypeScript port of Pete Rager’s Python lennoxs30api, the local S40/S30 payload is already providing this sensor data during the long-polling process, but it isn't being parsed or exposed as Service.TemperatureSensor and Service.HumiditySensor … Excerpt saved from GitHub on 2026-10-22. | Issue #1 · 2026-06 |
