Quick verdict
A 6-zone valve controller built on the ShellyX chip, offering complete offline setup via an on-device web interface plus MQTT and the local Shelly HA integration. It runs Shelly's local firmware with an on-device web interface and MQTT, and HA's Shelly integration controls it directly on the LAN. Just note: Newer/less battle-tested than OpenSprinkler.
Standout: A 6-zone valve controller built on the ShellyX chip, with complete offline setup via an on-device web interface plus MQTT and the local Shelly HA integration.
