# Lennox S30/E30

> Lennox S30/E30 is a Marketplace integration for Home Assistant. It has 699 installs sharing analytics, works locally and was last updated October 24, 2026.

Lennox S30/E30 is an integration that connects Lennox S40, S30, E30 and M30 thermostats to Home Assistant. It works locally, and setup also offers a Lennox cloud connection alongside the local one, both configured in the UI. It adds climate control along with binary sensors, buttons, numbers, selects, sensors and switches. Optional extras include an allergen defender switch, temperature and humidity sensors, an inverter power sensor, diagnostic sensors and equipment parameters. Advanced connection settings cover scan intervals, fast scans, communication timeout and debug logging, and a diagnostics file can be downloaded for bug reports. It needs the Marketplace, or HACS on version 2026.10 and older.
