1-Wire bus (on RJ12 connector) - measurement of up to 8 DS18B20 temperature sensors.
I2C bus (together with 1-Wire on RJ12 connector) - for connecting various devices, e.g. temperature and humidity sensor AM2320 or BME280, OLED display, others. List of supported sensors below.
Serial bus (UART) - support various sensors and GSM modem.
Modbus RTU bus (requires tHAT expansion board or Modbus RTU adapter) - built-in support for many modules, e.g. energy meters and PV inverters, plus the ability to integrate other devices using the custom device configuration function.
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.
1 relay (NO, C, NC).
1 transistor output - supply voltage at the output, to control loads with a current consumption of up to 1 A.
4 outputs for switching relays, transistors in OC standard.
4 PWM outputs with frequency range from 1 to 1 000 000 Hz.
Measurement of supply voltage and temperature on the board.
Software
Convenient and complete configuration of the device and all its functions through an intuitive web interface.
Possibility of own configuration of the Status panel - uploading your own background, selection and placement of necessary readings and buttons.
Two levels of access (login) - as an administrator for configuration and as a user to view the Status.
Events - a feature that allows you to define automatic actions triggered by specific conditions – such as changes in device parameters or values read from sensors.
Scheduler - a feature that allows you to schedule automatic actions based on time – as one-time events, recurring at defined intervals, or at specific hours in a daily or weekly cycle.
Support for modern protocols: SNMP, HTTP, MQTT, SMTP, with TLS/SSL encryption for secure communication.
HTTP client that make it possible to configure and control other devices. For example, controlling Wi-Fi relays (Smart Relay) or displaying sensor readings on the camera image. It supports authentication methods like Basic Authentication and Digest Access Authentication.
Sending e-mail, MQTT or SMS notifications (requires tHAT2 overlay with GSM modem) as a result of an event.
Sharing device data and sensor readings via the built-in Modbus TCP server.
Remote control from one to many devices via UDP - useful as an implementation of the button over the Internet.
Time synchronization with the Internet (NTP).
Possibility of collecting data from all connected devices and sensors, remote switching of outputs via the MQTT protocol in our service mqtt.ats.pl and mobile application.
Many functions available through the above service, such as setting reactions and tasks (performing actions under certain conditions and at a certain time) covering multiple devices.
