Implements device-type support for `COMPACTn` (device type ID 30) as discussed in #218. ## Changes 1. Added `30: "COMPACTn"` to `CTS602_DEVICE_TYPES` in `custom_components/nilan/device_map.py`. 2. Added `30` to the `supported_devices` tuples of every entry where device 44 (CompactP AIR/GEO sibling) is present, non-HPS entries and HPS-specific entries alike. (The HPS entries previously only listed `(44,)`, so they were not actually exposed for type 30 before this patch.) 3. Added `CompactP (Polar/Nordic)` to the supported-devices list in `README.md`. ## Testing Patched integration has been …

Add support for VPM/28EC

Summary Fixes the entity mapping for device type 11 (`VP 18comp`). On this unit a number of registers return valid values, but no entities are created because `supported_devices` either omits `11` or is set to `(None,)`. All changes are limited to device type 11, no other device type is touched. Verified against a real VP 18 M2 (`Control.Type` = 11, `Bus.Version` = 23, controller software 3.6.64) by reading all 293 registers of the CTS602 / HMI350T Modbus specification v23 with the integration disabled, and cross-checked against the manufacturer documentation for this unit (installation …

Hi I have an old Nilan Comfort 300 from 2010. On the panel it says software 2.00. I have bought a Waveshare RS485 TO ETH (B) and configuret it. I got the link, and installed the HACS integration, but I don't get any entities is just blank? I have tried to switch A/B on RS485, but then it says unsupported device. So it looks like the connection is there. I have activated debugging, and it can read device type, bus version, but device software is blank ? 2026-03-14 13:51:11.543 DEBUG (MainThread) [custom_components.nilan.device] Setup has started 2026-03-14 13:51:11.653 DEBUG (MainThread) …

Why Adds support for the Nilan CTS400 / ES1077 controller (Comfort 250 Top) alongside the existing CTS602 integration. The CTS400 uses a different Modbus register space, cannot be auto-detected (it has no CTS602 `control_type` register at holding 1000), and only supports function codes FC03/FC04/FC06. It therefore can't be added as a small CTS602 "device key" and is wired as a distinct board family. This is ready for review, opened from a fork, and refs discussion #165. It is additive only - no CTS602 behavior changes. ## Provenance and verification - Verified live on a Nilan Comfort 250 Top …

Summary Adds support for monitoring and controlling an earth tube preheater (puits canadien) connected to a Nilan CTS602 unit (device type 28). - `get_t17_preheater_temperature`, temperature sensor (T17) for the earth tube inlet, mapped to `sensor` entity (already existed in `device.py`, now wired through `device_map` and `sensor`) - `get_preheat_fan_speed`, actual fan speed readback from register `output_pre_heat_cap`, exposed as a `sensor` (%) - `get_preheat_cap` / `set_preheat_cap`, fan capacity setpoint 0–100%, exposed as a `number` slider All entities are scoped to `supported_devices: …
