-HMI panels are useful devices that can make control of various automation projects (boiler control, smart home control, industrial production control etc.) much easier. If you then need to connect HMI panel to the Mervis IDE, you can do so using the BACnet protocol over LAN.
+If you need to connect the Mervis IDE and the HMI display using a local network, you can use the BACnet protocol. For your project, you can use the HMI, in this case, the Weintek touchscreen HMI display, for system control, production control, boiler control, home control, etc.
