`switch`	Switch or outlet
`climate`	Thermostat
`binary_sensor`	Sensor (motion, contact, leak, smoke…)
`sensor`	Sensor (temperature, humidity, air quality…)

Device	In Home Assistant	In Apple Home	What they said	Source
Nilan Comfort 300LR (Comfort Light, CTS602 light)	Works Local		Wrong values until gateway power-cycled; then T9 and light-variant sensors added Saved copy That might be the first CTS602 light i have encountered. So nice of you to create the issue. In the identifiers the "SDM" value is 0, however for the Comfort Light it should have been 2, thus the wrong model gets loaded. You can see that it loaded CTS602 instead of CTS602light. In the Nilan app, what model does it display? Excerpt saved from GitHub on 2026-10-23.	Issue #19 · 2025-01
Nilan CTS400 ventilation unit	Partly works Local		Sensor addresses reportedly differ from other Nilan libraries; values mismatch app Saved copy It seems like the addresses in the GenvexNabtoCTS400 for the sensors does not match the addresses in the other Nilan libraries. From what i can find, ex. https://github.com/nic6911/ESP32_Modbus_Module/blob/main/esphome_example_code/Nilan_cts400.yaml has the addresses that matches my test results (image placed last in this comment) Excerpt saved from GitHub on 2026-10-23.
