VEdirect victron node

General

Hello.
I’m using this node to acquire data from a Victron smartshunt.
I find a problem of which I cannot understand the nature, questioning him I obtain alternately in seemingly random way this information:

`{"PID":{"value":"0xA389","product":"SmartShunt 500A/50mV","description":"ProductID","units":""},"V":{"value":54033,"description":"Main or channel 1 (battery) voltage","units":"mV"},"I":{"value":8191,"description":"Main or channel 1 battery current","units":"mA"},"P":{"value":443,"description":"Instantaneous power","units":"W"},"CE":{"value":0,"description":"Consumed Amp Hours","units":"mAh"},"SOC":{"value":1000,"description":"State-of-charge","units":"‰"},"TTG":{"value":-1,"description":"Time-to-go","units":"Minutes"},"Alarm":{"value":"OFF","description":"Alarm condition active","units":""},"AR":{"value":0,"description":"Alarm reason","units":""},"BMV":{"value":"SmartShunt 500A/50mV","description":"Model description (deprecated)","units":""},"FW":{"value":412,"description":"Firmware version (16 bit)","units":""},"MON":{"value":0,"description":"DC monitor mode","units":""}}`
{"H1":{"value":-169877,"description":"Depth of the deepest discharge","units":"mAh"},"H2":{"value":0,"description":"Depth of the last discharge","units":"mAh"},"H3":{"value":-26402,"description":"Depth of the average discharge","units":"mAh"},"H4":{"value":37,"description":"Number of charge cycles","units":""},"H5":{"value":0,"description":"Number of full discharges","units":""},"H6":{"value":-41542003,"description":"Cumulative Amp Hours drawn","units":"mAh"},"H7":{"value":50363,"description":"Minimum main (battery) voltage","units":"mV"},"H8":{"value":59022,"description":"Maximum main (battery) voltage","units":"mV"},"H9":{"value":0,"description":"Number of seconds since last full charge","units":"Seconds"},"H10":{"value":487,"description":"Number of automatic synchronizations","units":""},"H11":{"value":0,"description":"Number of low main voltage alarms","units":""},"H12":{"value":0,"description":"Number of high main voltage alarms","units":""},"H15":{"value":0,"description":"Minimum auxiliary (battery) voltage","units":"mV"},"H16":{"value":0,"description":"Maximum auxiliary (battery) voltage","units":"mV"},"H17":{"value":221642,"description":"Amount of discharged energy (BMV) / Amount of produced energy (DC monitor)","units":"0.01 kWh"},"H18":{"value":231236,"description":"Amount of charged energy (BMV) / Amount of consumed energy (DC monitor)","units":"0.01 kWh"}}

these should be correct and I get the main parameters

{"H1":{"value":-169877,"description":"Depth of the deepest discharge","units":"mAh"},"H2":{"value":0,"description":"Depth of the last discharge","units":"mAh"},"H3":{"value":-26402,"description":"Depth of the average discharge","units":"mAh"},"H4":{"value":37,"description":"Number of charge cycles","units":""},"H5":{"value":0,"description":"Number of full discharges","units":""},"H6":{"value":-41542003,"description":"Cumulative Amp Hours drawn","units":"mAh"},"H7":{"value":50363,"description":"Minimum main (battery) voltage","units":"mV"},"H8":{"value":59022,"description":"Maximum main (battery) voltage","units":"mV"},"H9":{"value":0,"description":"Number of seconds since last full charge","units":"Seconds"},"H10":{"value":487,"description":"Number of automatic synchronizations","units":""},"H11":{"value":0,"description":"Number of low main voltage alarms","units":""},"H12":{"value":0,"description":"Number of high main voltage alarms","units":""},"H15":{"value":0,"description":"Minimum auxiliary (battery) voltage","units":"mV"},"H16":{"value":0,"description":"Maximum auxiliary (battery) voltage","units":"mV"},"H17":{"value":221642,"description":"Amount of discharged energy (BMV) / Amount of produced energy (DC monitor)","units":"0.01 kWh"},"H18":{"value":231236,"description":"Amount of charged energy (BMV) / Amount of consumed energy (DC monitor)","units":"0.01 kWh"}}


These contain information but not what I expect.

this happens randomly alternating, a deploy is the only way I’ve experienced to get it back to "normal" but suddenly then change again.
Has anyone had experience with this knot?
