Hi guys,
I'm using SmartShunt to measure and visualise time to go of my RV battery, working great. For screenshots and more here is a project: https://github.com/mman/node-red-dashboard-ismove
When SmartShunt periodically sends time to go when battery is discharging, the value is averaged over recent consumption interval and is very useful.
However whenever charging starts - such as when solar panels kick in, the smart shunt stops sending the time to go value as soon as the flow of the energy goes to the battery, in other words as soon as the battery stops discharging.
Although technically and mathematically correct, it is not useful at all for example in an RV or Yacht, because it displays time to go as infinity, but that is not correct, as soon as the sun stops shining, time to go will drop back again.
What I did is to remember the last time to go value, and display it along, since "actual" time to go has not changed that much and will probably not change much for as long as batteries stay at around the same SoC. So I display the last value with "+" attached indicting that SoC is going up.
Am I the only one who finds this a bit confusing? Thoughts?
