I have a remote off grid site, running a Raspberry Pi for monitoring and it is supplied by a 48Volt Battery Bank. Raspberry Pi + 4G Modem consuming together about 4W continuous power. The current measurement resolution shown in Venus is 100mA leading to a 5W resolution on a 48V battery bank. If no load is active except the RPi, I have a flipping DC consumption monitored and shown in Venus. So the VRM charts look like:
With a fully charged battery it gets logically worse, leading to zero consumption for longer periods:
Is there a way to improve this?
