How the parts connect

PanelHeat AI, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

Today they pay for a cellular alarm dialer (Mission M110 $1,195 plus service, about $55 per station per month in a Florida utility filing), drive the round to read gauges and pay for a yearly heat survey.

2. 27 Oct 2026, 09:15Small towns, water districts and private owners (HOAs, RV parks, mobile-home parks) have three jobs at every pump station: answer the alarm, know each pump is still pumping, and catch a hot connection in the panel. Daily lift-station checklists list alarms, levels and pump readings (MaintainX), pressure is read with pumps off and running (Indiana DNR), a site visit costs $500–2,000 or more (Vista Projects), and a cellular dialer alone is $1,200–1,600 (Mission, Sensaphone). Our own three products for it cost $2,827 and $87 a month per station.

3. 27 Oct 2026, 07:18In a dusty plant (sawmill, joinery, feed mill, recycling plant) the electrical room is where dust and electrical heat meet. Washington L&I's sawmill dust alert lists electrical arcs as an ignition source, and NFPA 652 asks for regular cleaning and control of ignition sources. Today the room needs three tools: a panel heat monitor, a thermal camera for growing hot spots and a dust monitor; our own three cost $4,979 and $80 a month for one room.
