Home Assistant

A dryer with a Link module publishes itself to Home Assistant via MQTT Discovery: HA creates the entities on its own — chamber readings, drying and storage start fields, buttons. The portal is not needed for this, everything goes through your MQTT broker.

Below: enabling the integration, verification and a ready-made card layout, so that the device looks like the picture rather than a list of entities.

Both dryer chambers on the Home Assistant panel: readings, drying and storage start, service.

Note

The device will not appear in Settings → Devices & services → Discovered: this is MQTT Discovery, not UPnP/zeroconf. The MQTT integration in Home Assistant must be added in advance.

What you need

1. An MQTT broker: the Mosquitto broker add-on in Home Assistant or any broker on your network.
2. The MQTT integration added in Home Assistant, pointing to that broker.
3. A dryer with a Link module on the network and Online on the portal.

Step 1. Enable the integration on the device

Open the device at portal.idryer.org and find the Integrations → Home Assistant block.

Field	What to enter
Host	the broker address on your network, for example 192.168.1.27
Port	the broker port, usually 1883
Username / Password	broker credentials, if it requires them
Discovery prefix	homeassistant, unless you changed it in the HA settings
Enabled	the checkbox — otherwise the device will not connect to the broker

The settings go straight to the device over the local network — the portal does not store them.

The broker address, port and the "Enabled" flag — everything the device needs.

Step 2. Find the device in Home Assistant

Settings → Devices & services → the MQTT card → in the Services section expand the broker node. iDryer devices are listed under serial numbers of the form DEVICE_*.

Devices under the broker node; the dryer shows its entity count.

Open the device: HA already shows the readings and controls. Check that the values are live — they update together with the device telemetry.

Step 3. Build the card

HA lays the entities out on its own, and the result is a long list. The ready-made layout groups them the same way as in the app: readings on top, then Drying, Storage and Service.

1. Settings → Dashboards → Add dashboard → an empty dashboard, open it.
2. Top right corner → the pencil (Edit) → the "⋮" menu → Raw configuration editor.
3. Paste the contents below and save.

The layout is designed for a dashboard of type sections.

The same layout in the dashboard configuration editor.

The second chamber

On a two-chamber dryer the entities of the second chamber are named the same way, but with u2: sensor.idryer_u2_temperature, button.idryer_u2_drying and so on. Copy the whole - type: grid block, paste it after the first one and replace u1 with u2 in it, and the heading with iDryer · Chamber 2. You get two columns side by side.

If the entity names do not match

The layout is designed for standard identifiers of the form sensor.idryer_u1_temperature. If the card shows "Entity not found", look up your own: Settings → Devices & services → MQTT → your device → the entity list — and replace the prefix in the layout with yours.

Troubleshooting

Symptom	What to check
The device did not appear in HA	On the portal the Home Assistant integration has the "Enabled" checkbox set, the broker address and port are correct. The device must be Online.
It appeared, but the values are Unknown	Wait for a telemetry cycle. If it is still empty — the broker does not keep retained messages or the device did not connect to it.
The buttons do not work	Check that the broker allows publishing to the idryer/# topics and that the device log has no authorization errors.
Ghost entities with the value Unknown	Retained messages from an earlier firmware are left over. Clear them: mosquitto_pub -h <broker> -t 'homeassistant/<...>/config' -n -r.
