I noticed that sometimes some data is not updating for a longer period. I noticed it because I set up my energy diagram to see also the heat pump consumption. When my total current consumption was high I checked the heat pump sensors and there was no data.
In the log below I got the part where the heat pump started (~19:02:32) and ended (~19:19:20). During that time some or no values at all were updated.
Side note: The "System Flow Temperature" from the myVAILLANT Home Assistant Integration was also not updated. The "Energy Manager State" seems also the be wrong.
Pump/compressor start was not counted.
"CurrentConsumedPower" was at 0.
"TargetFlowTemp" was also down to 0°C during that time and still is after.
But some other data were being updated.
Like the VR70 sensors, or "ebusd_hmu_status01_temp", "ebusd_hmu_status01_temp_1", "ebusd_hmu_flowtemp".

After some time I got some important data (almost 1 hour later they were finally updated):
CurrentConsumedPower
CurrentYieldPower
EnergyIntegral
FlowTemp
Here the snippet from the logs starting with CurrentConsumedPower and ending with FlowTemp
