Interesting, for front-defroster I either see the value '3' when off, or the value '1' when enabled at any level. I have never seen true, false, or null values for this field.I've seen that return null, true, false, and '3' As near as I can tell 'true' means on, and all other values mean false - if you look at 3rd party Tesla apps, they often screw up and show the front defroster as 'on' because they interpret '3' as non-zero/non-null and think it means "on". Nope, "3" is sometimes returned for off for some reason.
If it's true the battery_current field is no longer provided in the latest firmware update, sad day... The streaming telemetry API provides current power, albeit imprecise as an integer.
