LAN controller with relay V4.0, wifi, MQTT, digital I/O, analog inputs, I2C, 1wire, RS485, modbus

The LAN controller with relay is a simple, versatile and affordable device for controlling outputs based on information from various sensors. It serves as a web server that displays different types of sensors and allows remote control of outputs. In addition, it is possible to program events and appropriate actions to meet conditions on any of the sensors. A scheduler that allows the device to be turned on/off at a specific time or for a specific period of time can be useful for many applications.

The new LAN driver v4.0 integrates all of Tinycontrol's existing IoT experience into one universal device. It is a seamless continuation of the previous series, now in a more practical form.

Dual communication interface:
You can use a wired Ethernet connection, wireless Wi-Fi, or both at the same time. A variant with LTE connectivity is also available. LAN Controller v4 can be fully configured from the website, available on the built-in web server. It is also possible to send any commands to the device via the HTTP protocol (omitting the website) or MQTT (after configuring the connection).

Differences between devices:

Hardware:

• 4 logic inputs - as a status sensor for opening monitoring, infrared motion sensors, for a button for manual switching with the option of bistable mode, as a pulse counter from the energy meter, as a time counter between subsequent input resets
• 2 analog inputs with switchable range (measurement up to 3.3V or 58V) - for measuring voltages, DC current, AC current (additional sensors), operating pressure sensors, thermocouples, distance sensors, photoresistors for lighting measurement and many others
• 1 analog input with switchable range (measurement up to 5V or 58V) - for measuring voltages, DC current, AC current (additional sensors), operating pressure sensors, thermocouples, distance sensors, photoresistors for lighting measurement and many others
• Measurement of supply voltage up to 58V
• Digital input in 1-Wire standard - measurement of up to 8 DS18B20 temperature probes
• Digital input in the I2C standard (together with 1-Wire on the RJ12 connector) - for connecting various devices, e.g. temperature and humidity sensors, air quality (PM) sensors, CO2 measurement sensors, OLED display with the ability to configure the displayed text and others. See the list of supported sensors below
• Serial bus (UART) - for connecting the devices and sensors listed below
• RS485 bus to support devices and sensors with the Modbus RTU protocol
• 1 relay (NO, C, NC) 10A/250V
• 1 transistor output - supply voltage at the output, to control loads with a current consumption of up to 0.6A
• 4 outputs for switching relays, transistors in OC standard
• 3 PWM outputs 1Hz to 1MHz
• Measurement of temperature and humidity on board
