   The whole PumpOne

   The lift station's own control panel runs the station watch: the station's level transducer and float and two current clamps on the pump leads give level and pump state, a camera and a radar behind the side windows see the hatch, the riser gauges and the gate, a heat camera on the door watches the breakers, and the brain on the back plate turns that into level, pump, power, entry and heat calls on the door's light and one app, over LTE-M.

2. 02Brain

   Raspberry Pi Zero 2 W (on the panel back plate)

   The brain: it runs the pumpone-fw program

3. 03

   Level and pump currents

   Reads the station's own 4-20 mA level transducer and high float, and a current clamp round each pump motor lead

   Raspberry Pi Zero 2 W (on the panel back plate) · I²C (ADS1115) + 250 Ω loop resistor and clamp burden on the back plate · Level and both pump currents at 860 samples a second; run, start and stop times

4. 

   04

   Station camera

   Looks out of the right side window, 15 degrees down: the wet-well hatch, the two discharge gauges on the riser and the gate

   Raspberry Pi Zero 2 W (on the panel back plate) · CSI-2 ribbon (300 mm, inside the panel) · A frame every 10 s; gauge stills on each pump run; 10 s clips around entry calls

5. 

   05

   Hatch radar

   Finds a person at the hatch or the riser through the side window, in the dark and the rain

   Raspberry Pi Zero 2 W (on the panel back plate) · UART · Up to 3 targets with position at 10 Hz

6. 06

   Panel heat camera

   On the inside of the door, looking back at both pump breakers, contactors, overloads and the terminal strip

   Raspberry Pi Zero 2 W (on the panel back plate) · I²C (door lead in a strain-relieved hinge loop) · 32 x 24 heat frames at 1 Hz while a pump runs

7. 

   07

   Display, call light, tone and secure element

   Level, pumps and the last call on the e-paper; red, amber or white on the call light with a tone; every call signed; the tamper switch marks the log when the door opens

   Raspberry Pi Zero 2 W (on the panel back plate) · SPI (e-paper) + one data wire (light) + GPIO + I²C · Readings, light colour and flash, tone, signatures, tamper flag

8. 08

   Power, backup and LTE-M

   5 V from the panel's own 120 V control circuit; a LiPo keeps the Walter board calling out over LTE-M when the station power is off

   Raspberry Pi Zero 2 W (on the panel back plate) · 5 V rail + UART to the brain · Power about 1.5 W (est.); callouts and the 15-minute log over LTE-M

1. 4 Nov 2026, 05:00LatestA utility buys PumpOne as the lift station's own duplex pump control panel, on its stand beside the wet well, on the panel's own 120 V control circuit. So the electronics must be boards an assembly house makes and tests the same way every time, inside the same 24 × 20 × 8 in stainless panel, beside its breakers and contactors, reading the station's own level and pump signals without ever taking over the pumps.

   • What we designed: three boards of our own inside the panel. An 8-layer main board stands inside the right side wall, towards the wet well, with the processor (a heat block to the stainless wall), memory, the security chip, the microSD card with our software, the LTE-M modem with a soldered eSIM and Bluetooth; two small tabs hold the camera chip and the 60 GHz radar chip just inside their windows. Below it, a power board beside the pump leads takes the panel's 120 V control circuit, a backup cell, and every station signal on spring-clamp terminals: both current clamps, the level loop through an isolated amplifier, the high float and both pump run calls through optocouplers, and a relay to the panel's own alarm light. A door board carries the heat chip looking back at the breakers, the e-paper, the call light, the tone and a door tamper sensor. See it at /build/pumpone-boards.
   • How we checked it: the boards are written as code and opened in KiCad (0 design-rule violations). The code places 62 parts at their sizes and checks each sits on its board inside the panel, with no overlaps and room for its height beside the panel's own breakers; that the lens and the radar chip sit 0.3 mm inside the wall; that the e-paper, LEDs and piezo sit in their door openings; and that all 13 station calls (the hatch and its corners, both riser gauges, the gate, a person at the hatch and the riser, both breakers, both contactors and the terminal strip) are in view from where the chips really sit. The design review runs every shared rule: 18 pass, 2 fixed, 8 to prove on the first boards, 0 fail.
   • What we learned: the bench LTE-M board and its antenna sat inside the closed stainless box, which stops the signal. A sealed 2-in-1 puck antenna now goes through the top wall under the station's sun shield, and the camera window grows from a 14 mm disc to a 20 mm square for our lens and the gate call; both drawn in the panel CAD in the same run, and all 13 CAD views still pass. That finding became a new rule for every board: a radio inside a closed metal box fails the review unless its antenna is outside the metal. DockOne, KitchenOne, PoolOne, RacketOne and ChillOne were re-checked against it the same day; each already uses a plastic window, and their reviews now name it.
   • What is next: the boards inside the panel CAD with the heat block, the tab brackets and the tamper magnet; LTE-M range under the sun shield at a rural station; and the next board, FootballOne.

2. 29 Oct 2026, 03:55A small town or water district with a handful to dozens of lift stations needs to know at once about a high wet well, a failed pump, a power cut or an opened hatch, and today drives to each station to read the gauges and pays for a yearly heat survey. It buys a duplex control panel ($1,000-1,244 for SJE Rhombus NEMA 4X panels at R.C. Worst) and a cellular dialer (the Mission M110 at $1,195 with a $575 yearly service package, as the City of Kittitas paid for 2026, or a Sensaphone Sentinel at $1,561.50 at CDW).

   • Buyer check with sources: SJE Rhombus panel prices, the Mission Communications yearly service package (Kittitas, 2026) and Novi install cost, Sensaphone Sentinel and its plan, pump-health software; no panel with cameras and calls built in found on the market
   • What we learned: the dialer service, about $48 a month per station, is the recurring cost every small utility already pays, and nobody sells the panel and the dialer as one item
   • Parts list prices checked on shop pages today: $1,446 per panel at qty 1 including the enclosure and the plain panel controls (we had about $1,480); the Pi Zero 2 W and Camera Module 3 Wide cost more, the secure element less
   • Price kept at $2,690 + $45 a month per station, about what a new panel and a dialer cost today ($2,300-2,800 + about $48 a month) with gauges, panel heat and the hatch added; cost about $1,786 at qty 1 and $1,260 at qty 100, a 34 % to 53 % margin (est.)
   • All 16 part fit checks and 13 camera, radar and heat views in the CAD still pass; about 24 h of callouts in a power cut rechecked; CAD review clean with no floating parts and no collisions
   • Product page: the first three FAQs answer why not a dialer and a plain panel, what it costs, and whether a working panel must be replaced; a power and size spec group
   • Next: three questions for utilities in customer reviews (a new panel or a retrofit kit, does our plan replace their dialer service and feed their SCADA, which extra call matters most), then SiteOne for construction and mining

3. 28 Oct 2026, 11:50A town or water district needs one thing at each lift station that calls high water, a failed pump, a power cut and entry to the person on call, as the Ten States Standards (section 46) ask, and that reads the gauges and watches the panel between rounds. 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.

   • Market check: who buys one product per lift station (small towns, water districts, HOAs and parks), what they pay for alarm dialers and service (Mission, Sensaphone), what a plain duplex NEMA 4X panel costs (about $1,084, Pollard Water), and the alarm, panel and wet-well rules (Ten States Standards s. 46, UL 508A, NEMA 4X, NEC, NFPA 820); sources in DESIGN.md
   • New CAD: the 24 x 20 x 8 in stainless duplex pump control panel with its door and back plate: a Raspberry Pi Zero 2 W brain, a level and current input board, two pump current clamps, LTE-M, a backup cell, a secure element and a tamper switch on the back plate; a station camera and a radar behind side windows; a heat camera, a display, a call light and a tone in the door; 16/16 parts fit from datasheets, 13 camera, radar and heat views checked, no collisions, no floating parts
   • equipment.json: 8 rules met (alarm list, UL 508A, NEMA 4X, same size, NEC working space, NFPA 820 distance, pump control kept hard-wired, radio); 8 calls (5 alone), 4 impact cases and every security key
   • idea.json station plan, integration.json (6 parts, 5 app screens with a No operator on site mode), bom.csv (about $1,480 a panel with its own controls, est.), buy.json with 10 key parts
   • New product page at /products/pumpone/ in Energy, Water and Utilities: $2,690 + $45/month per station against about $3,911 + $87/month bought separately (est.); folds PumpStation, LiftStation AI, GaugeRead AI and PanelHeat AI; MotorPulse AI stays listed for motors outside the wet well; next: F16 Construction and mining sites

Smart equipment · legal on the field

PumpOne is the duplex lift-station pump control panel, made smart

It replaces the station's plain duplex pump control panel (breakers, contactors, alternator, level controller, alarm light and horn), in the same size, on the same stand, with the same pump leads, float cables and level transducer; the panel builder fits our back plate, door and side windows as one UL 508A listed panel, with every part built in. Everything inside the plain 24 x 20 x 8 in panel: brain, station camera, radar, heat camera, level and current inputs, LTE-M, backup cell, display, call light, tone, secure element and tamper switch. About +600 g over a plain panel (est.); no pole camera, wet-well sensor, fence box or separate dialer.
