Ideal or Cost Effective Home Charging

Was there some nonesense that it needed to be 100% charge to update the UMC?? I could be making that up……
It may have been just after a charge is complete.
Requirements for 10A and 15A charging are:
1. Minimum software version 2021.12.25.7
2. Tails that have "10A" and/or "15A" written on them
3. Charging completion (eg. If car is at 60%, set it to 61% and let it complete) and leave plugged into car.
4. Power-cycle of UMC after update.
(possibly) 5. Connected to Wi-Fi.
1. It's 2022.8.2
2. Tail has 10a on it
3. Left it for a couple of hours for 2 nights after charge completion
4. Tried that. No effect
5. Connected
The current options I can select are from 5a to 8a.
I guess I have to try the happy dance now
Lol the dance worked!
It went to 10a this morning. Tesla needs to add it to the manual

We should all accept that doing the happy dance is an undocumented feature.Lol the dance worked!

A great write-up:
I use the UMC / 32A tail option.
Really appreciate you sending that thank you.A great write-up:

This is definitely not required, I have updated two UMCs without WiFi connected. The UMC update is fully contained within the updated car software - if your car software is new enough, it will update the UMC (it can also update HPWCs as well the same way!).
You should try to unplug the car for 5 or so minutes and then replug. Restart the app and then it should be showing the increased amps. This is on the proviso that car has reached the set SOC and has had a chance to sleep directly after reaching the set SOC This should allow the UMC to update. That worked for me.
Yes I do.
Should I not lock it and see if that changes anything?
I have restarted the app, restarted the car, done everything else mentioned but still showing 8amps
No, I was thinking the other way around - when I was testing it, locking the car seemed to kick the update off sooner, but it might have just been coincidence.
charging the car today in the backyard using my lovely gen 3 wall connector - two week old car, only the second time I’ve done it
I noticed on the app that the interior temperature is 38°
I’ve turned on the a/c to cool it down
does this happen often?
edit: I’ve discovered ‘cabin overheat protection’ in the app but it says it comes on when the temp reaches 40°

You might be better off posting in the New Zealand forum for this type of question! But plenty of people here will say 15A socket plus UMC is plenty for overnight charging if you don’t do a lot of k’s every day. I think the need (or not) for Type B RCD depends on the appliance that is connected not the Amperage. Also NZ wiring rules might be subtly different to AUS.
