Know before it costs you money.

Small WiFi sensors at your furnace and water softener. When something actually needs attention, a person at K&H tells you in plain words.

The K&H sensor — a compact branded enclosure, designed and assembled by K&H

How it works

No wiring, no app to fight with, and no jargon when it matters.

  1. We set it up

    A small WiFi sensor installs at your furnace or softener. We handle it.

  2. It learns your home

    Every system is different. The sensor spends about a day learning what normal looks like on yours.

  3. You get told in plain words

    “Your filter needs changing.” “Your salt is low.” A person reviews it before you’re ever told to act.

Products

Two sensors, both monitored live and reviewed by a person.

Monitored live

Furnace Filter Sensor

Stop guessing about your filter. The sensor measures how hard your blower works to pull air through it and tells you when it actually needs changing — by the airflow, not the calendar.

Readings every 30 seconds · paired sensors agree within 0.008 in. w.c. · 90 days of history
Filter dashboard: filter life remaining, trend chart, and plain-words verdict
Monitored live

Salt Tank Sensor

Never run your softener dry. It watches the salt level in your brine tank so you refill when it matters — no more checking a bucket in the basement.

Why you can trust the alert

The numbers behind “something needs attention” — and the person who checks them.

30s

A fresh reading from your system every thirty seconds.

0.008

Paired sensors agree within 0.008 in. w.c., so a reading is real, not noise.

90 days

Ninety days of history, so a trend is a trend before you hear about it.

A person

Someone at K&H reviews what the sensors learn before you’re told to act.
