I’ve published a native Zigbee driver for the Zemismart ZMS-206EU-2 two-gang screen switch. It pairs directly to Hubitat and creates a separate child switch for each wired relay.
The parent device provides controls for screen names, backlight brightness, indicator colors, radar wake timeout, child lock, per-relay countdowns and power-on behavior. Fixed choices are available as dropdowns in the device commands.
Install: Use Hubitat Package Manager → Install → From a URL with the package manifest, or import the raw Groovy driver in Drivers Code. After pairing or assigning the driver, run Configure on the parent device.
Testing: This is a v0.2.0 preview. I tested one ZMS-206EU-2-B (TS0601 / _TZE28C1000000_dmckrsxg) for both relays, state updates, ASCII and Cyrillic screen names, and readback of the 60-second radar timeout. Other settings and hardware revisions have limited live testing.
