Our verdict
A Zigbee valve/pump that turns a plant monitor's readings into actual watering instead of a nag notification. We paired it with the Smart Soil Moisture Sensor Gen2 and built a moisture-tiered automation — the drier the soil, the longer the valve runs — with an explicit Home Assistant shutoff on top of the device's own timer, because a stuck-open valve is a real flooding risk you shouldn't trust to firmware alone. One gotcha worth flagging up front: it has its own onboard watering schedule that will fight a Home Assistant automation unless you set it to 0.
What can Home Assistant control on the Third Reality Smart Watering Kit Pro (3RWK0148Z)?
The device's built-in water_interval config entity runs its own onboard watering schedule independent of Home Assistant — if you're driving watering from an HA automation, set water_interval to 0 first or the plant can get watered twice (once by the device, once by your automation). Its own moisture probe only reports wet/dry, not a percentage, so pairing it with a separate percentage-reporting sensor (like the Soil Moisture Sensor Gen2) gives finer-grained dosing control.

Frequently asked questions
- Does the Third Reality Smart Watering Kit Pro (3RWK0148Z) work with Home Assistant locally?
- Yes. The Third Reality Smart Watering Kit Pro (3RWK0148Z) is controlled locally in Home Assistant through Zigbee2MQTT or ZHA (ZHA / Zigbee2MQTT), so it keeps working if your internet connection or the Third Reality cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Third Reality Smart Watering Kit Pro (3RWK0148Z) use, and do I need a hub?
- The Third Reality Smart Watering Kit Pro (3RWK0148Z) uses Zigbee. To pair it with Home Assistant you need a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host. Third Reality's own hub is not required when you integrate through Zigbee2MQTT or ZHA (ZHA / Zigbee2MQTT).
