Installation/Configuration
1. Install and activate the plugin like any other plugin. If you’re new to HS4, here is how:
• Go to your HomeSeer Web Control page.
• Use the Plugin dropdown and choose Add.
• Use the (2
nd
) Search bar, or scroll to OTGW Plugin.
• Choose Install.
• In Plugins > Installed use the toggle to turn on the plugin.
2. Configure:
• Go to Plugins > OTGW Plugin > Add OpenTherm Gateway.
• Follow the steps:
o Choose Continue at the introduction step.
o Enter the IPv4 address of the OTGW. Choose Continue.
o Enter the port number that goes with that IP address. Choose Continue.
o Optionally enter a name for this OTGW. This is useful when you have more than
one. If you don’t enter a name, the IP and port will be used. If you now continue
by choosing Create Device/Features, the entered information will be validated and
the device and a few of its features will be created. After that, the connection to
the OTGW will be made.
Noteworthy
• Other features will be added only as soon as a matching message is received. This way
you will only get features that are actually supported by your thermostat/boiler.
• However, it may take hours before every message was received, possibly even a day (for
instance for the date feature).
• Please note that if your thermostat/boiler would support all messages you may end up
with 150+ features.
• You may want to hide features that are of no use to you. Do not delete features.
Also, you may want to restrict access to certain features for certain users for
safety/security reasons. You can do this by clicking on each feature and under User
Access remove the Any checkmark, chose your (admin) account(s) instead and then
Save.
• A timeout is applicable. If the plugin does not receive an OT message for 2,5 seconds, it
assumes the connection is down, it will write a warning to the Log and tries to reconnect.
Meanwhile the plugin will not receive OT messages, so features may not be entirely up to
date for a while. If this happens often, you may want to check how your OTGW is
connected to your network: Wi-Fi reception may be poor, or you have a faulty cable.
During timeout at least 2 messages are missed (According to the OT Specification there
should be a message at least every second, with a 15% margin). The total number of
missed messages depends on how fast the plugin can reconnect.
