Tinycontrol LAN LK4.
Improvements over the previous version
The module has a number of improvements compared to the previous version V3.5 .
- Expanded Communication Capabilities : The LK4 offers a dual communication interface, allowing you to use both an Ethernet connection and wireless WiFi. Thanks to this, the user can easily adapt the device to his preferences and needs.
- Modern user interface : the controller has a responsive web interface that is easy to use and allows full configuration of the device directly through a web browser. Moreover, the user can customize the status panel to his needs by selecting and arranging the necessary readings and buttons.
- Increased configuration capabilities : LK4 offers advanced configuration functions such as setting conditions and tasks, event scheduling and the ability to read from your own Modbus RTU devices. Moreover, the user can use many modern communication protocols, such as SNMP, HTTP and MQTT.
- Greater flexibility and support for a variety of devices : The controller supports a wide variety of sensors and devices, so it can be used in a variety of applications, from smart home to renewable energy and industry.
- Increased performance and security : thanks to TLS encrypted connections for HTTP, SMTP, MQTT and SNMP v3, it provides greater security of data transmission. Additionally, modern hardware and software make the device work more efficiently and stably than the previous version.
To sum up, the LK4 controller offers greater configuration possibilities, higher performance, greater flexibility and security, and easier operation thanks to a modern user interface and mobile application.
