Web Remotes

Industrial & IoT

Web panels for sensors, relays and machines. Good for learning, testing and small plants. A web panel must never replace a real emergency stop.

Watch a PLC-controlled machine from any browser: running state, part count, speed, temperature, OEE and last alarm.

Read and write a Modbus device from your browser: switch coils, set a holding register and read input registers.

Send commands to an RS485 device from your browser: set baud rate and address, read status, start, stop and reset faults.

A general MQTT device controller: switch an output, set a value, pick a mode and see readings from any MQTT device.

Control an 8-output industrial relay board from a browser, with a motor interlock option and 24V supply monitoring.

Start and stop a machine remotely through its own start/stop circuit, with status, run hours and fault reset.

A web thermostat for heaters, ovens, incubators and baths: live temperature, set point, automatic on/off control and an alarm output.

Hold humidity at your chosen level for mushrooms, incubators, stores and labs with a web humidity controller.

Keep water or air pressure steady: live pressure, automatic pump control below a set point and a low-pressure alarm.

Run a pump station from a browser: duty and standby pumps, auto or manual mode, sump level and outlet pressure.

Control and monitor a motor on a VFD: run, speed and direction, with current, temperature and frequency readings.

A combined dashboard with four sensor readings and four relays. The classic ESP32 starter kit project, ready to use.

Manage your IoT devices from a browser: see online count, firmware, Wi-Fi signal and uptime, and ping, reboot or update them.
