It seems that the MQTT broker from Cayenne doesn’t support the Retain policy at this moment. This means that I have to wait for the next publish event until I see data in my dashboard. I use Cayenne to monitor my car data, and the tracker send new data every 60 minutes if the car is not driving, so this takes a while.
It would be nice if I could see the most recent values immediately.
It would be even nicer if Cayenne also stores older values so you could even display graphs and GPS movements immediately. I am aware that this requires myDevices to use a time series database to store these values, but if more people are interested in this feature it might be a paid feature to store history values.
