Unofficial integration, not affiliated with Legrand. It turns on and off the lights of a Legrand In One (powerline, "CPL") installation from Gladys, and shows their state when someone presses a wall switch.
What you need
- A Legrand USB / RS232 interface, reference 882 13, plugged into the machine that runs Gladys.
- A small "serial gateway" container that exposes this USB device on a TCP port. Gladys integrations cannot access USB devices directly, so this container does it for them (see the project README for a ready-to-use
docker-compose.yml).
Setup
- Start the serial gateway container. By default it listens on
172.17.0.1:2000. - Install this integration and check the address and port in its settings.
- Press each wall switch once. The Legrand bus cannot list its devices, so the integration learns each circuit from the frames the switches send when they are pressed.
- Open the Discovery tab and run a scan. Each circuit seen on the bus appears as a light named
Legrand <id>-<unit>, followed in brackets by the kind of device:(inter)for a switch,(inter scenario)for the on/off key of a scenario switch. This is deduced from the keys heard so far: a scenario switch whose on/off key alone was pressed first shows as(inter), then turns to(inter scenario)once one of its scene keys is heard. Create the circuits you want and rename them.
If a switch does not appear, press it again and rescan. The list of known circuits is kept across restarts.
What it does
- Turns lights on and off from Gladys (dashboard, scenes, voice).
- Updates the state in Gladys when a wall switch is used.
- Shows each Legrand scenario button as a button in Gladys (
Legrand scenario <id>-<unit>). It clicks when the scenario is pressed, so you can use it as a trigger in Gladys scenes.
Linked devices
The bus never reports the state of a receiver. When a button drives several lights (a group, a scenario), only the button sends a frame and the lights stay silent. The settings Rule 1 to Rule 12 (one rule per field) tell the integration which lights follow which button. Nothing is sent on the bus: only the state shown in Gladys is updated.
Use the circuit numbers printed in the logs (944559-1). One rule per field. If you need more than 12 rules, put several in one field, separated by ;:
648966-1 -> 944559-1, 944559-2
648966-2 -> 944559-1=on, 944559-2=off
Several rules in one field: 929520-1 -> 944561-1; 929523-1 -> 944561-1.
- With a light on the left, the lights on the right copy its state (on, off), whether it comes from a wall switch or from a command in Gladys.
- With a scenario button on the left, each light on the right takes the fixed state written after
=(onoroff).
Tested hardware
This integration was developed on one installation, with:
- the Legrand PLC/USB interface ref. 882 13 (seen by Linux as a BTicino "SFERA Tele Loop" USB serial device);
- double transmitter-receiver switches ref. 672 02 (two directions: top key = on, bottom key = off);
- a single transmitter-receiver switch ref. 672 01 (frames received and decoded; command from Gladys not tested);
- a lighting scenario switch ref. 672 08 (on/off keys + two scenario keys);
- a scenario transmitter ref. 672 80 (four scenario keys);
- Gladys Assistant 5.3 on a Home Assistant Yellow (64-bit ARM).
How to read the devices in Gladys
In the In One system every product has a unique identifier, and every receiver learns the transmitters that drive it (LEARN key). Only transmitter orders travel on the bus: "direction 1 of transmitter 944559 says on". The receivers that learned this transmitter react, silently.
So a device Legrand 944559-1 in Gladys is a transmitter key (identifier 944559, direction 1), not a lamp. Driving it from Gladys is like pressing that key: every receiver that learned it reacts. This is why a transmitter learned by several receivers switches several lamps, and why the state of a receiver can never be read: it does not exist on the bus. The Linked devices setting describes these associations so that Gladys shows the right state.
References of the In One PLC range
From the Céliane technical guide. Only the four references above were tested; for the others the "Expected" column says what the protocol suggests, without verification.
Lighting
| Reference | Product | Expected |
|---|---|---|
| 672 01 | Single transmitter-receiver switch 2,500 W | Tested for reception; command expected to work like the 672 02 |
| 672 02 | Double transmitter-receiver switch 2 × 1,000 W | Tested |
| 672 03 / 672 04 | Single / double switch with indicator | Like 672 01 / 672 02: should work (the indicator is local, nothing on the bus) |
| 672 08 | Lighting scenario switch (on/off + 2 scenarios) | Tested |
| 672 15 | Automatic switch 1,000 W (motion detector) | Should send on/off orders like a switch |
| 672 10 / 672 12 / 672 14, 036 10 | Dimmers 300 W, 600 W and DIN dimmer 1,000 W | On/off only; no level control in this version |
| 882 03 | Plug-in dimmer 500 W | On/off only |
| 882 00, 882 01, 882 15, 882 20 | Infrared/radio remotes and scenario controls | No: they do not use the PLC bus, except through a PLC/IR receiver that relays |
Scenarios
| Reference | Product | Expected |
|---|---|---|
| 672 80 | Scenario transmitter (4 scenarios) | Tested |
| 672 84 | Touch-screen scenario manager | Its scenarios should show up as buttons; not verified |
Roller shutters and blinds
| Reference | Product | Expected |
|---|---|---|
| 672 51 / 672 55 / 672 56 | Individual shutter switch (plain, with override, with programmable level) | Not supported in this version (up/down/stop orders, another family of the protocol) |
| 672 53 / 672 54 | Central control / group control (4 zones) | Not supported in this version |
Heating, detectors, interfaces: thermostats 674 40 / 674 42, cable outlet 674 45, local override 674 48, programmer 674 49, detectors 675 22 / 675 23 / 675 24, interfaces 036 06 / 036 07 / 036 18 — outside the scope of this integration. Filters 882 12 / 882 21 / 882 23 are passive accessories.
If you test one of these references, say so on the project's GitHub repository: the table will be updated.
Limits of this version
- The bus never reports the real state of a receiver. The state shown in Gladys is deduced from the frames and from the commands sent, so it can drift (for example after a Legrand scenario that switches lights off). A command from Gladys always puts it back in line.
- To keep Gladys up to date after a Legrand scenario, use linked devices (rule
scenario -> light=on). - On/off lights only: no dimmers, no shutters, and Gladys cannot start a Legrand scenario.
