Read water and electricity meters by camera,
without replacing the meters you already have
Fit an ESP32-CAM sensor over the meter you already have. The device takes the picture, reads the digits itself, then sends the reading — together with the photo it read them from — back to this server over Wi-Fi. You check the numbers on the web instead of walking the site to write them down.
How the trial works
Create an account
Sign up with your email address. Accounts are still approved by hand, so an administrator opens yours for you — usually within the same working day.
Register your sensor
Give the sensor an ID and enter the Wi-Fi network at the installation site. The server issues that one device its own API key and MQTT credentials — nothing is shared with another customer.
Download the config files onto the SD card
Your sensor page offers a sdcard.zip download. Unzip it straight into the root of the SD card, then put the card back in the device.
Power it up and watch
The device joins Wi-Fi and starts reporting on its own. Readings, photos and history show up on your sensor page right away.
Why your data never mixes with anyone else's
Every sensor has its own identity
The API key and the MQTT credentials are generated per device the moment you register it. There is no shared key.
The broker enforces the boundary
A sensor's MQTT credentials can only publish and subscribe on that sensor's own topic prefix; the broker refuses every other topic.
Every query is filtered by owner
Every page and every API that reads data filters by owner, image paths included — another customer's URL cannot be guessed.
