 This integration guide assumes that Teslamate is deployed on docker and that Node-RED will not be exposed to the internet. Of course, you can install Node-RED outside of Docker and on another server, it that suits. The integration with Teslamate is entirely via MQTT. Notifications included in the examples are sent using available Node-RED modules for email and Telegram. Other notifications (e.g. Slack) are relatively simple by replacing the final node in the Notifications flow. One could also integrate with public tools such as IFTT. Or get really creative and integrate with Alexa or Google Assistant to control the car by voice. :)
