I am running Venus-large and have a fairly extensive Node-Red flow consisting of about 100 nodes. My router is reporting a permanent TCP/IP session with one of the mqtt{1 to 128}.victronenergy.com servers with constant traffic of just over 10 kbit/s upload and just under 1 kbit/s download. This seems high to me but maybe it's because of my 100-node flow. Is this level of traffic to be expected?
