You can use this node to integrate the battery voltage reading into your control strategy to do whatever you want, like activate an alarm when it drops below a certain threshold. This would be useful to let an operator know that retained settings will be lost when the controller loses power due to the battery voltage being low. Download the JSON file or text file from our website and import into your Node-Red. If your controller does not have access to the internet, do not worry, this node only uses CORE nodes to operate so nothing needs to be downloaded for this to function.
