High and low temperature texts include the actual reading. Door and window status shows if something changed.

Know it is online

If it loses power or stops checking in, designated people get a text or email.

Need leaks or HVAC? Plug in a module.

The Building Sensor is the box on the wall. A module snaps into the bottom jack for a specific job. One module at a time. Extra modules are $75.

  • WaterBug: two leak detectors
  • HVAC: supply and return probes
  • Same Building Sensor for freezer and cabinet setups

What you get

Put it in the room you cannot watch all day. It logs temperature, watches the door, and texts you when something is off.

  • Temperature history and high/low alerts with the actual reading
  • Door and window status
  • Text or email if it goes offline
  • Live screen plus caltuck.cloud

Install

Mount it where problems start: basements, garages, mechanical rooms, vacant suites, or access doors.

Monitor

It reports to the cloud every few minutes and immediately when an alert event happens.

Alert

You get SMS or email before a small issue becomes frozen pipes, spoiled product, or an expensive response.
