In short

UMD Switched is the official companion app for Ultimation Direct's Bluetooth relay time clock, letting users connect over Bluetooth Low Energy without Wi-Fi or an account. It offers manual relay override, weekly scheduling, live status and an activity log, and it needs the matching ESP32-S3-Relay-1CH hardware. It suits installers commissioning or handing over gate installations. It reads the relay's stored configuration on connect rather than overwriting it.

About

UMD Switched is the official companion app for Ultimation Direct's Bluetooth-enabled gate relay time clock.

Connect directly to your relay controller over Bluetooth Low Energy — no Wi-Fi, no cloud account, no subscription. Configure schedules, check relay status, and override manually, all from your phone.

FEATURES • Direct Bluetooth connection to your relay hardware — works entirely offline, no internet required • Manual override: switch the relay ON, OFF, or send a test PULSE • Weekly scheduling: set latching ON/OFF events for any day, any time • Live relay status, read straight from the device — always shows what's actually programmed, even from a different phone • Activity log of manual and scheduled relay changes • Automatic UK time zone and daylight saving handling, so schedules fire at the correct local time year-round

BUILT FOR THE FIELD Whether you're commissioning a new gate, checking an existing installation, or handing a site over to a colleague, UMD Switched always reads the relay's real configuration on connect — never guesses, never silently overwrites what's already set up.

REQUIRES An Ultimation Direct Bluetooth relay time clock (ESP32-S3-Relay-1CH). This app does not work as a general-purpose Bluetooth relay controller.
