Victron Connect History showing actual days, not active solar days as expected

I have a SmartSolar 100/30 MPPT which is connected to my RV - so it sees intermittent use - around 50 days per year. I happy with the performance of the unit - and the charts and graphs really helped me understand and track our electricity usage. However during one of the constant updates, the behavior of the History feature changed - happening maybe the last quarter of 2019? Previously, each day in the history was triggered by a charge cycle - the solar panel seeing sunlight and charging the battery. Times / days when the panel was disconnected from the system were ignored. And my panel is disconnected / dark when the RV is not being used. This app behavior was exactly what I wanted to see.

Subsequent to this fateful update, the History chart is now determined by calendar days - apparently by the clock in in the smartphone. Now all the days in between my RV trips are filled in with blanks - making the History function mostly useless for me. How can I get back the previous functionality? For stationary application - where the solar system is used every day, this change doesn't make any difference. But for me - where I use the solar system intermittently - this change crippled one of the most useful tracking features in the software.

So looks like there's no hope of getting any help with this. I noticed that someone rewrote my title - but missed an important point. The actual title should be -

Victron Connect History showing actual days, not active solar days as it originally did.

Sorry @JeffB,

I thought that I replied to this when I changed the title.

I asked the developer of VictronConnect and he will ask one of the MPPT firmware developers if anything has changed there.

Thanks for the reply!

There was definitely a change in the behavior of the Victron Connect History chart - maybe the last quarter of 2019. There is no possibility that panels are connected - the cable is unplugged and the panel stowed inside. Although the charge controller does remain connected to the battery. I haven't yet tried disconnecting that.

The behavior continues - I've just got 30 days of blanks in my History chart, and my last charge cycle was June 4th. The Victron Connect version is 5.27. Although there will probably be a new update when I fire up the system in a couple days.

I am very willing to believe this was an inadvertent change. You won't even notice unless you run a test where the usage is intermittent. Daily use continues to look just the same as it always has.

I have got some information back;

It will change to a new day every 24h, or if it sees the sun rising again after having seen 4 hours of day and 4 hours of night the previous day, while the battery is connected.

This was changed a while ago.

What you can do to pause the timer is isolate both panels and battery from the MPPT, then days won't change until the battery and/or PV is reconnected.
