At this time the Venus GX counters appeared to suddenly transpose ie D1=D5, D2=D4, D3 remained the same. The Venus GX was not touched nor the wiring and has been working almost 12 months without any problems.
I'm at a loss as to the cause. Any ideas?
No wiring was changed and it was the counters on the Venus GX and VRM data which changed.
By way of example, D1 is connected to a tipping bucket rain gauge and D5 is a solar energy meter with pulse output 3200/kWh. Up to 29th May D1 has a very low count then suddenly gets a daily large number from the solar energy meter.
