Hi All, I had a Powerwall 2 installed on Nov 23rd along with SunPowr solar panels and Solaredge Inverter. I appreciate is possibly not a good time to do it, however it took months to get DNO approval as we were above the 4Wh 'notification' line at 5kWh. Located in Derbyshire, UK. Needless to say I was very busy in the run-up to Christmas and much as I should have been learning I let it slip until now. My background it IT before retiring has led me to wanting to monitor everything. hmm. Solaredge seems to have some good reporting but of course it does not see everything so I am reliant on what the Tesla app tells me as I cannot find an API or any better reporting. Maybe I'm doing this all wrong but I have two current 'problems' and the following points sum up the situation. 1: I'm baffled by the difference between Advanced Balance and Advanced Cost Saving. For me I'm struggling to find a significant difference in the way it behaves. 2: To start building up a profile of how my system is performing I collect the information from the app for yesterday first thing in the morning. I discovered that it cant add up! If I look stats for 3rd Feb app and select solar it reports 0% of output to grid, yet if I then look at the grid it shows 2.7kWh to grid. Other numbers look OK, but what other traps are there. 3: In part of the world we've seen a really nice sunny day followed by a few bad days. That seems to result in the battery not charging from grid overnight and us taking some peak rate energy towards the end of the day. Is there a way I can force it to top up overnight? I cant find one. 4: To add to the confusion we have only two different tariffs, low and high. low times are 22:30-00:30 and 02:30-07:30. I think I can only have one low tariff time so I've set it to 02:30-07:30. That high tariff from 00:30-02:30 is a pain, if I were cynical I'd say it was to trip users up and get them to put stuff on overnight ... at peak charge. The problems: 1: How do I monitor this system automatically without having to key in loads of data daily from an app that looks all very nice but might just have a maths problem? 2: Is there a clear doc that explains how the management works such that I can check I've got it configured correctly (not that there is a lot you can do)?
