Hi, I’m using a BHT-006 thermostat (Tuya-based Zigbee) with Homey Pro (2023). The thermostat itself supports 0.5°C increments (e.g. 21.5°C), and this works correctly on the physical device. However in Homey: - Setting the temperature to 21.5°C results in 21.0°C - Reading target\_temperature always returns an integer (e.g. 21 instead of 21.5) - measure\_temperature does report decimals correctly (e.g. 21.5) It looks like target\_temperature is being rounded down (floor), possibly due to parseInt / Math.floor in the driver. This causes issues in automation (e.g. heating control with hysteresis), since the actual setpoint is higher than what Homey reports. Question: Is this a limitation of the Tuya/Zigbee mapping, or a bug in the Homey driver? If this can be fixed, it would be great if target\_temperature supports decimals (0.5°C steps), consistent with the device itself. Device: BHT-006 (Tuya Zigbee thermostat) Homey: Homey Pro 2023 Happy to help test a fix if needed. Regards, Bart ---

You’d ask the app developer, in the related app topic (mentioned on the app page @ homey.app Target temperature capabilities are (and should be) usually capable of 0.5°C steps. Alternative: When you don’t mind installing a beta firmware, try to pair it as generic zigbee device (without app), because support for thermostats is recently added in [beta firmware v13.1.0-rc.x](https://homey.app/en-us/wiki/homey-pro-firmware-changelog/) ![Screenshot_20260325_235544_Ecosia](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/a/ca2070f9522fb3726245274916b4cec01aeed032.jpeg) Otherwise you’d wait for the live firmware version to be published (usually in a few weeks). ---

Which app do you use? If you use the Tuya Zigbee app, you likely won’t get the issue resolved since the developer is no longer active. You can also use a Tuya ZigBee/MultiMode gateway and use the official Tuya app to add your thermostat > **[Tuya | Homey](https://homey.app/en-us/app/com.tuya2/Tuya/)** > > Smart Life.
