You can "stream" the data from the SmartMeter if you get the right kind of Zigbee device. Then you can do whatever you want with the data at almost any interval you care to measure and store.Thanks.
When you say 'utility meter' , you mean to physically goto the ,meter to check the usage in real time ? or is their any other way to get this data ? I guess it takes 24 hours for this data to be posted on the PGE portal and then i can see some charts . Is that what you are referring to ?
In my case, part of it is just interest and excitement to monitor these things and also ultimately to charge my EV directly.
I mean why should i spend so much money to buy a power pack , when i have much bigger battery already at home , which needs to be charged . On weekends , uptill 2 PM the TOU rates are same as night time.
Stream Your Data
The key point you will need to address is how you bridge this information gap between knowing what your solar and your utility meter is saying about your production and consumption and making decisions about how to control an EV charging. This can be done with OpenEVSE or SmartEVSE (European type) if you are a programmer, but I don't know of a commercial offering that will "just work" out of the box. Eventually, I would expect Tesla to offer this kind of software interface and integration, but it must not be a high priority since it's a relatively esoteric feature for most people.
