What is Tinajon Pro?
Tinajon Pro is an automatic water pump controller designed for homes with an intermittent water supply. Built especially for Cuba, Venezuela and rural areas of Latin America where water isn't always available when you need it, it measures your tank level with an ultrasonic sensor and turns the pump on or off by itself — no climbing to the roof to check, no remembering to do it manually.
How does it work?
The ultrasonic sensor, mounted on the tank lid, measures the distance to the water several times a second. You set two numbers from the app: the minimum distance (full tank) and the maximum (empty tank). From that, the controller calculates the level as a percentage and decides when to act — turning the pump on when the level drops below the threshold you set, and off once it reaches 100%. No manual intervention, no risk of overflow, never running out of water.
Three modes, you decide how much control you want
Not everyone wants the same level of automation, so Tinajon Pro offers three operating modes you can switch between with a tap in the app or the device's physical button:
Automatic: starts on its own at the % you choose and stops on its own at 100%. The mode built for forgetting about the tank entirely.
Semi-automatic: you start the pump whenever you want, and the system stops it on its own once it hits 100% — useful if you'd rather decide when to fill but without risking an overflow.
Manual: full control in your hands. The pump won't stop on its own even if the tank is full — only you decide when to turn it off.
Built for places where water isn't a guarantee
Most smart water level controllers are designed assuming stable WiFi and monthly fees. Tinajon Pro starts from the opposite premise: it was built from the ground up for Cuba (Nauta Hogar, pay-by-time internet), Venezuela and rural Latin America, where "24/7 home internet" isn't something you can take for granted. That's why the whole system — sensor, pump, app — works perfectly offline, and the cloud is never a requirement, only an extra.
Local-first, cloud-optional
Most importantly: it works without internet. On your home WiFi network, your phone talks directly to the device — no external server involved. If you don't even have home WiFi, the controller creates its own private network that you connect to from the app. The cloud is entirely optional and adds extra features when you do have internet: full event history, remote control from anywhere, and Telegram alerts when the level drops, the pump turns on, or something needs your attention. If the internet goes down, nothing essential stops — only those extra features pause, and everything syncs automatically once the connection is back.
Protects your pump, not just your water
Automating the fill-up doesn't help much if the system doesn't also protect the hardware. Tinajon Pro builds in several layers of protection for exactly that:
Safety stop at 100%, so the tank never overflows.
Configurable flow watchdog: if the pump has been running for a while and the level isn't rising, it stops itself and flags a fault — preventing it from running dry because of an empty source or a mechanical problem.
Optional cistern sensor (float switch): if the water source has no water available, the system won't start the pump even if the tank is low.
Configurable minimum pause between consecutive starts, so the motor isn't forced through back-to-back cycles.
The magnetic contactor stays open by default if the power goes out — the pump can't start on its own when power returns until the system takes back control first.
The device
One device, well thought out: an OLED display so you can see the status at a glance without opening the app, a buzzer for sound alerts, and two physical buttons with combinations to restart, reset WiFi, or restore factory settings. The water level controller mounts near the pump and runs on direct line voltage (110V or 220V, auto-adjusting), driving the motor through a solid-state relay and a magnetic contactor — no external power supply or adapters needed.
