Serial Connection

Although this plugin does not natively support using a serial connection (USB/COM/TTY), there are

ways to connect an OTGW that has no LAN/Wi-Fi yet:

1. Use a free COM/TTY port to IP address redirector to connect. They can easily be found

through an internet search engine.

2. Use Schelte Bron’s Opentherm Monitor to connect via serial port (Options > Connection >

Serial port. Set the radio button and choose the Serial device).

Then use its relaying function under Options (Configuration) > Remote Access. Enable both

Enable relay server and Relay opentherm messages. Modify the Server port if needed. Then

add the OTGW to the plugin with the IP of the machine running Opentherm Monitor and the

port you have set for relaying.

Note you may want to save resources by:

• Running Opentherm Monitor with parameter –deamon, which will make it run without GUI

and save resources.

• Disable Logging.

Thanks to forum user mo046 for this addition.
