My VRM page is recieving zero values from my virtual device, at start-up or nede-red deploy.
I tried to catch all zero values in my function and in the debug window i do not see these zeros.
In moste cases these zeros are harmless, but especially for calculating the correct consumption it is quite anoying. Becaus this leads to unrealistic spikes in the VRM view.

Does any one has an idea what am i missing?
Or is this a bug that other have seen to.
