    OMG! This is becoming quite a comedy!

    I left it with my electrician that they (his company) would order the meter so that we get it right. I just got a call from the company saying they wanted to run the purchase by me before pulling the trigger on the order. I asked what kind they were getting, and heard that it was an 'EKM 120/240' meter. I then asked for the model number - and it was the one I'd just sent back!

    He was about to make the same mistake I had! While the waste of time & additional shipping expenses are frustrating, at least I feel ever so slightly less stupid.

    Don't feel stupid, the top line labeling is indeed poor and misleading. The portion showing that it doesn't work for you is buried well below that.

    Agreed. That was some really bad labeling.

    Ta da!

    Finally got the correct meter installed. My EVSE is padlocked in. I see up a charging schedule. Driving on EV tomorrow! :)

    Woke up to a charged car with predicted EV mileage of 35 miles. :)

    One quick question - the kWh meter measured 7.12 kWh. With an 8.8 kWh battery, I was assuming a full charge would be more like 6.5 kWh. Should I expect a broader range of charging times for a "depleted" battery?

    There will always be some variability due to the amount of the hybrid vehicle mode charge that is depleted. Still, it makes sense to monitor several charges.

    Another potential load would be cabin/battery heating/cooling that increases the electrical load during the charge. For example, hitting "A/C" button on the key fob:

    This is from charging on a +90F day.

    Here I've hit the "A/C" button:

    You can see where the A/C came on to chill the cabin.

    You might check at a hardware store to see if you can get a thermometer to clip-on/glue to the wall. Just record the kWh and temperature to see what is going on. Alternatively, NOAA makes climate data available from local airports.
