Gardena Smart Irrigation Control (19032-20)
- Bluetooth
Verified August 2026
The garden equivalent of a smart wall switch: a six-valve irrigation controller that talks Bluetooth directly to a phone (or Home Assistant, via a Bluetooth proxy if the controller's outdoors and out of range of your HA host) without needing Gardena's optional Smart Gateway hub at all. That's the appeal over Gardena's cloud-tied 'smart system' line — schedule watering per valve locally, and it keeps working even if Gardena's app backend has a bad day. Range is the catch: Bluetooth-only means you'll likely need one or more ESPHome Bluetooth proxies between the shed and the house for reliable HA control.
In Home Assistant
Home Assistant's core Gardena Bluetooth integration connects directly over BLE (via Settings > Devices & services > Add Integration > Gardena Bluetooth) and exposes per-valve switch entities plus battery and connectivity sensors — no Gardena cloud account or Smart Gateway required for basic on/off and scheduling control from HA. The device remembers only its last 10 paired Bluetooth adapters, so if you rely on an ESPHome Bluetooth proxy to reach a controller mounted outdoors, that proxy must be paired once before it can hand off connections reliably — swapping proxies later can require re-pairing.
