This plug-in is meant to connect your Green Mountain Grills WiFi Smoker to HomeBridge, so you can add it to HomeKit. Your smoker will need to be in WiFi mode, and discoverable by the app for this to work.
You will need to select the Polling Interval (this is how often the app will poll the GMG to update the device status) which is measured in seconds. The value must be between 1 and 600. Default is 30.
If you are using DHCP to keep your grill on a certain IP, you can enter that in the IP Address field, otherwise the plugin will attempt to discover the grill automatically.
The GMG Client library is adapted from https://github.com/Aenima4six2/gmg
If you find this useful and have a few extra bucks lying around, you can send a donation with PayPal or venmo, so I can buy more IoT devices. :-)
