Hi all
I have a number of NodeRed flows setup to monitor battery voltages sent as MQTT from an ESP82666.
They work fine except when the MQTT data stream is interrupted.
In this instance the NR dashboard Gauge simply freezes with the last message payload displayed.
I am trying to find a way to zero the gauge by changing the payload message to 0 if no message received in say 1 minute so that I get warning of a sender failure.
Im sure I need to use the Trigger Node but I cant get it to work.
Any ideas ?
