Remote Tank Starter
Everything you need to watch one water tank from anywhere. The package includes 1 Tank Transmitter, 1 House Gateway and private website access. The Tank Transmitter is solar powered, with its panel, charge controller and battery already wired together, so there is nothing to charge or replace. The House Gateway plugs in indoors and connects to your Wi-Fi.

Tank Transmitter With Solar & Tank Sensor
The Tank Transmitter sits at your water tank, measures the water level and sends it wirelessly to your House Gateway. It is fully solar powered: a solar panel, a built-in solar charge controller and a rechargeable internal battery come wired together, so there are no batteries to take out, charge or replace. The dashboard shows each transmitter's battery level. Every account has its own private key, so your tanks only talk to your gateway.
Pump Relay Add-On With Unlock
This is an add-on purchase. It is the relay that lets you control your water pump from your dashboard, and buying it also permanently unlocks pump control on your account. You choose the level where the pump stops and the level where it is allowed to run again, and you can press Emergency stop and Resume right on the tank's card on your dashboard. Pump size: This relay is rated for 120 volt pumps up to 5 amps when wired directly. If your pump is 120 volt and draws more than 5 amps, you will need a contactor. If your pump is 220 to 240 volt, you will need a 2-pole contactor with a 120 volt coil, rated for your pump. How the contactor is used: The bottom of our control box has two labeled wire connectors for this purpose, HOT IN and SWITCHED OUT. The box itself is never opened. The contactor is mounted in its own separate enclosure, outside the control box. Connect a 120 volt hot wire from a nearby source to the HOT IN connector. Connect the SWITCHED OUT connector to one of the contactor's coil terminals. Connect the 120 volt neutral wire from the same source straight to the other coil terminal. The wires that used to run from your 240 volt breaker to your pump (or to its pressure switch) connect to the contactor's L1 and L2 terminals. New wires from T1 and T2 go to where those original wires connected, and your pressure switch stays where it is. When the relay closes, the pump can run. When the relay opens, or power is lost, the pump stops.

House Gateway (Inside Home)
The House Gateway sits indoors, plugs into any USB power adapter and connects to your Wi-Fi. It listens for your tank transmitters over a long-range wireless link and sends every reading securely to your private online dashboard, so you can check your water levels from anywhere. It is the first piece you set up, and it is what links your tanks to your account.
Long-Range Pro
For properties where the tank is too far from the house. The package includes 1 Tank Transmitter, 1 House Gateway, 1 Bridge Repeater and private website access. The Tank Transmitter and Bridge Repeater are both solar powered, so neither needs an outlet, Wi-Fi or battery changes. The repeater carries your tank's readings to the gateway. Your private website dashboard is included at no extra cost: • Live tank levels, water usage and connected status • Email alerts based on water level: getting low, critically low and full
- 1 Tank Transmitter, solar powered
- 1 House Gateway (plugs into any USB power adapter)
- 1 Bridge Repeater, solar powered
- Private website access
Multi-Tank
Watch two tanks on one dashboard. The package includes 2 Tank Transmitters, 1 House Gateway and private website access. Both transmitters are solar powered with nothing to charge or replace, and each tank gets its own level, warnings and water-usage page. Your private website dashboard is included at no extra cost: • Live tank levels, water usage and connected status • Email alerts based on water level: getting low, critically low and full
- 2 Tank Transmitters, solar powered
- 1 House Gateway (plugs into any USB power adapter)

Solar Bridge Repeater
The Bridge Repeater picks up the readings from your tank transmitters and passes them on, so a tank that is too far from the House Gateway can still report. Like the transmitter it is fully solar powered, with a solar panel, built-in solar charge controller and rechargeable internal battery wired together, so it needs no outlet, no Wi-Fi and no battery changes. It checks in with your account regularly, and the dashboard shows whether it is Connected.
How it works
Three parts, no wiring to your house.
Sensor on the tank
A solar-powered transmitter reads the water level and sends it over a long-range wireless link, even to a tank far from the house. Nothing to charge or replace.
Gateway at home
The House Gateway sits indoors on your Wi-Fi, collects every tank's reading and sends it securely to your account.
Dashboard anywhere
Open your private dashboard on any phone or computer. Save it to your home screen and it opens with one tap, with nothing to download.
Get an email when your water needs attention
Wherever you are in the world, you will know before a tank runs dry.
Getting low
Choose the level you care about. When the tank drops below it, an email lands in your inbox right away.
Critically low
A second, more urgent alert for when it is really time to act. We keep reminding you every few hours, on a schedule you choose, until the tank is back up.
Tank is full
Know the moment a refill is done. You get a note each time the tank reaches full again.
Alerts go to your own email, and you can add as many family members or company addresses as you like. Every alert can be switched on or off for each tank.
Control your water pump from anywhere
Protect your pump, and save your water, even when you are far from home.
Stops before it runs dry
Choose the water level where the pump should shut off. If the tank drops that low, the pump stops by itself, so it never runs dry and burns out.
Starts again on its own
Choose a second level for turning the pump back on. Once the tank has filled back up past it, the pump is allowed to run again. Two separate levels keep it from switching on and off at the edge.
Emergency stop button
Watching your tank drain much too fast? Open your account from anywhere, tap Stop pump, and it shuts off right away. When you are ready, tap Resume pump and your levels take over again.
Its own pump card
Your dashboard shows a pump card with whether it is connected, whether it is in normal operation or stopped, and whether the pump is running right now. The Stop and Resume buttons are right on it.
You set the numbers
Pick any levels you like, such as stop at 20% and restart at 30%, and change them any time from your account.
Works with your pump
It switches the power signal your pump's control already uses, the same place a float or pressure switch is wired. If power or the sensor is ever lost, the pump stops. Have a qualified person do the wiring.
What you get
Everything is in your own account.
Live tank levels
Level in percent and estimated gallons for every tank, on one page.
Email alerts
Set your own warning and critical levels. Each tank turns amber or red, and we email you when it gets low, again as a reminder, and when it is full. Send alerts to family or your company too.
Pump control
Turn your pump off when the tank gets too low and back on when it has refilled, using levels you choose. An Emergency stop button is always one tap away.
Water usage
See how much water each tank uses per day, week and month, and reset the counter any time.
Connected status
Every sensor, gateway and repeater shows Connected or Not connected, plus its battery level. Solar-powered units keep their own battery charged.
Grows with you
Start with one tank and add more sensors later. Everything shows up in the same account.
Solar powered
Tank Transmitters and Bridge Repeaters come with a solar panel, charge controller and rechargeable battery already wired together. No batteries to remove, charge or swap.
Private by design
Each account has its own secure key, so your sensors only ever talk to your gateway.
Which one is right for me?
Answer two quick questions. It takes about a minute.
Does your tank have Wi-Fi?
Walk out to your tank with your phone and check whether your home Wi-Fi works there. Full bars aren't needed, just a connection that loads a web page.
Is there an outlet near the tank?
A spot for a small USB charger and cable is all it takes.
Outlet nearby: choose Combo Plug-in. One board reads your tank and connects to your Wi-Fi, powered by a plain USB-C cable. No battery, no solar panel.
No outlet: choose Combo Solar. The same one-board setup, powered by its own solar panel and rechargeable battery that come already wired together. Nothing to charge or replace.
Two ways to fix it
Easy first try: if you can, move your Wi-Fi router closer to the tank, or put it near a window facing the tank. Then check again with your phone. If it works, go back to the Combo options.
If that isn't possible: use the House Gateway setup. A solar-powered Tank Transmitter at the tank does not use Wi-Fi at all. It reaches your House Gateway indoors from a long way away, even miles, as long as there is a clear line of sight between them.
- Remote Tank Starter: one tank
- Multi-Tank: two tanks
- Long-Range Pro: one tank plus a Bridge Repeater, for when hills, trees or buildings block the way
You can add a Bridge Repeater to any of them later if your tank turns out to be hidden from the house.

Ways to set it up
Pick the layout that matches your property.
One board does it all
The Combo Gateway reads the tank and connects to your Wi-Fi itself. The simplest setup when the tank is close to the house.
Sensors out, gateway in
Put a Tank Transmitter on each tank. The House Gateway indoors collects them all, up to the range of the wireless link.
Add a Bridge Repeater
If a tank is too far from the house, place a Bridge Repeater between them. It passes your tank's readings along, runs on its own solar panel, and needs no outlet or Wi-Fi.
Everything in one place
Home, cabin, ranch: add devices from every location to the same account and see all your tanks on one page.
The wireless range depends on terrain, trees and buildings. A Bridge Repeater is the easy fix when a tank is out of reach.
How to calibrate your water tank sensor
Calibration teaches the system what "full" and "low" look like in your tank. The tank must be completely full at least one time to do it correctly. If your tank is only partly full when your kit arrives, do steps 1 and 2 now and finish the rest the first time it is full.
- Install it. Mount the Tank Transmitter (or Combo Gateway) and give it power: plug it in, or for the solar version mount the solar panel where it gets sun.
- Run the sensor cable into the tank. Do not kink it. Never crease or sharply bend the cable, because it carries a small air tube the sensor depends on. Going up and over something is fine, as long as the bend stays smooth and round.
- Fill the tank all the way to its normal full level.
- Set FULL. Lower the sensor to the very bottom of the tank, or to your pickup pipe if it sits a few inches off the bottom. That is where "empty" really is, so that is also where the sensor will live. Wait 5 to 6 minutes for the next reading. Then open the tank's settings on your dashboard and tap "Use current reading as FULL" (or type the number in).
- Set LOW. Lift the sensor so it hangs about 3 to 4 inches below the water surface. It must stay under water the whole time. Wait 5 to 6 minutes for the next reading, tap "Use current reading as EMPTY", then Save.
- Put the sensor back at its starting spot, at the bottom or the pickup pipe, and leave it there. That's it.
