i am still on 1.15.0 and have had TBC since Saturday i think. NorthCal, no solar.
Since enabled, it worked fine (even when it has connectivity issues due to my AP failing).
Aside from the obvious app changes i observed :
* much higher/faster charging rates from grid (used to be 3.3kw for 2 pw, now 7kw most of the time but sometimes 10kw as well)
* the wizard does not have self-consumption/backup selection anymore. instead it has "autonomous" mode only and no other choices avialable. Even though i know for sure 0.15.0 had these before. seems like a switch that has locked firmware to these choices without upgrading firmware. Interesting.
* it does not have to be online and connected to Tesla services to do the switches, i guess that's why it is called "autonomous". I guess that's also why it took longer -- apparently this is quite a rewrite in the firmware as well as services. There obviously some stat models predicting the use to figure whether to charge or standby in the shoulder (partial peak) to make sure the peak is always covered by the use shift.
All in all seems nice. I have but one complaint -- the app might include a button to switch discharge/charge/standby modes immediately, overriding the default decision. I have my own itility for that for now though. This may be needed when i charge-up my cars during the day or AC, in which cases sucking it up from the battery (during partial peak) will deplete its capacity enough to jeopardize total peak coverage. I may simply know expected day use much better then their algorithm forecast.
PPS make sure to enable DNS bypass in the router. The firmware also seems to be ignoring dhcp DNS hand-out, and as a result, the "tesla connected" status will show false. My router was dropping outbound DNS requests (as a security setting) that bypass its own service and that does not work, at least with 1.15.x maybe others too.
