Time based control and powerwall

It would be great if time based control using a Tesla Powerwall, could automated with ohm connect. Then during an ohm hour the system could switch to discharge from the powerwall, automatically.

    Tesla probably has their own plans for demand reduction, so I wouldn't hold my breath for them to implement a real third-party API. I have a homebrew version that uses IFTTT to automatically switch to self-consumption mode at the beginning of OhmHours and switch to backup at the end. Unfortunately the local API doesn't allow switching to TBC, so I have to do that by hand. If I have an OhmHour that's contiguous to my peak period (which ends at 7pm), I just manually extend the schedule instead.

    Can OhmConnect with Sonnen battery / powerwall?

    Is there an update on this topic? I am scheduled to get a Tesla Powerwall (2) installed and would like to know if the consumption mode can be changed automatically during Ohmhours through e.g. an API or IFTTT.

    Not through any official means yet, although I know OhmConnect was working on a connection at one point. I'm doing it myself using the reverse-engineered Tesla API and IFTTT, but it's somewhat involved to set it up.
