Temperature & SOC reading dips

On my gen2 hybrid 5Kw system with 2 x 9.5 GE batteries on 3015 and 914. I have noticed that the secondary battery graphs are showing random dips in the temperature and more occasionally SOC to zero. Is anyone else seeing this?

Ortwin Yes, happens every now and then even with one battery. Its a comms issue (ie timeout/error) rather than a battery problem.
