LinkTap Smart Water Timer

Quick verdict

LinkTap stands out from other hose-end timers with its built-in flow meter and exceptional wireless range via a dedicated gateway. The timer talks to the gateway over sub-GHz radio (not WiFi), and the gateway can run fully local over MQTT to Home Assistant or use the LinkTap cloud. The downside is needing the gateway hub. For large properties where WiFi timers lose signal, LinkTap solves a real problem.

Standout: Built-in flow meter with leak detection alerts, plus exceptional wireless range via a dedicated sub-GHz gateway.

Compatibility snapshot

Why it stands out

• wireless range between gateway and timer is excellent, far better than typical WiFi or Bluetooth timers
• built-in flow meter detects unusual water usage and can alert you to leaks or broken sprinkler heads
• solid build quality designed for year-round outdoor use

Reasons to hesitate

• requires a separate LinkTap gateway hub, not a standalone WiFi device
• cloud is the default path; local MQTT control takes extra setup
• Home Assistant integration is community-maintained and limited in functionality

Best for

• homeowners with large yards who need reliable wireless range to a distant faucet
• anyone who wants flow monitoring to detect irrigation leaks or broken heads

Avoid if

• you want a simple standalone WiFi timer without an extra gateway hub
• you want zero cloud setup and refuse to configure local MQTT

Privacy and local-control notes

Uses a gateway hub. The timer communicates with the gateway via sub-GHz wireless, not WiFi; the gateway connects to your LAN. The gateway can publish to a local MQTT broker for cloud-free Home Assistant control, or use the LinkTap cloud for scheduling and remote access.

Home Assistant support: supported · integration path: LinkTap (community; local via gateway MQTT or cloud API).

Buying reality check

Price notes: The timer and gateway are often sold as a bundle. The gateway can support multiple timers. Battery lasts about a year with typical use.
