Hi, I have a Zooz ZEN55LR DC Signal Sensor (also sold as « Smoke & CO Detector Bridge ») that’s fully recognized and interviewed in zwave-js-ui but shows as « not yet supported » in Gladys.
Device details:
- Manufacturer: Zooz
- Product: DC Signal Sensor
- Product code: ZEN55LR
- Device ID (from zwave-js-ui): 0x027a 0x0004-0x0110
- Firmware: v1.50.0, SDK v7.18.8
- Security: S2 Authenticated, fully paired
- Z-Wave+ certified, standard Z-Wave protocol (not using Long Range mode in my setup)
What the device does:
It’s a multi-endpoint device with three functions on one node:
- A relay/binary switch output (for controlling lights, sirens, etc.)
- Smoke alarm detection, reported via Notification Command Class
- CO alarm detection, also via Notification Command Class
Configuration parameter 8 (« Enabled Features ») is set to [4] « Relay, smoke & CO sensor » so all three are active and reporting.
Current status:
zwave-js-ui shows the device fully interviewed with all endpoints populated and reporting correctly. Gladys connects to the same MQTT broker and topic prefix and sees the device, but flags it « not yet supported » with no option to expose any of its features, only a generic Migrate option that doesn’t map it to a usable device class.
Happy to provide the JSON export from zwave-js-ui’s « Export json » function, MQTT topic dumps, or anything else useful. Let me know what would help.
