Pleased to report that the Ted reading and the meter reading still match exactly.
The load profile to match the hotwater heater seems reasonable but I don't trust that it's 100% catching every minute the heater is running. I'll be getting my arduino current measuring going again soon. I plan to use the arduino just to know that current is flowing and not care what the value returns as then use the TED measurements to Come up with real power used values.
