Rain Bird
Rain Bird is one of the largest irrigation manufacturers in the world, and its ESP-series controllers are a professional staple. Adding the LNK/LNK2 Wi-Fi module gives Home Assistant local control through the core Rain Bird integration, but skip the Rain Bird 2.0 app and firmware migration, which moves controllers to the IQ4 cloud and breaks local access.

2 devicesESP-ME3 + LNK2
Rain Bird's modular step-up controller: 4 stations on the base unit, expandable to 22 with hot-swappable 3- and 6-station modules, the right pick for larger properties. With the LNK2 Wi-Fi module installed, Home Assistant controls every zone locally through the core Rain Bird integration, with rain delay, schedules, and rain-sensor state included.
ESP-TM2 + LNK2
Rain Bird's workhorse residential controller in 4, 6, 8, and 12-station models, made smart by snapping the LNK2 Wi-Fi module into the faceplate. Home Assistant's core Rain Bird integration talks to the module locally: per-zone switches, a rain-sensor binary sensor, schedule calendar, rain delay, and a start-irrigation action with custom runtimes.
