How you setup Festival Grid depends on your network configuration.
Festival Grid interacts with your measurement hardware through device templates. Out of the box, Festival Grid supports any device that can run the open source tasmota firmware (a list of devices supported bytasmota can be fround here). see “writing new device templates” if you plan to use yet unsupported hardware. pull requests are welcome!
on the “nodes and devices” page, click the “scan” button. Festival Grid will scan the ip range you specify and add all found devices to its database.
192.168.1.0/24 will scan every ip from ..1.1 to ..1.254 (currently only ip4 adresses are supported).
