I don’t leave mine plugged unless it needs a charge. Mine’s garaged so I don’t need sentry on. If it were outside, I probably would have sentry and leave it plugged in to top up what sentry uses.Quick extra question
Plugged in all the time or only plugged in for a charge?
Aware there was something Elon said apparently about plugged in Tesla being happy Tesla??
Does this make a difference?

Thanks allJust leave it plugged in. If your Anderson charger is doing the timing, then the car will not be drawing any power outside the scheduled charging period, and if you need a top up just tell the Anderson to start a charge.
If you get into the habit of plugging it in every time you get home, you are less likely to get up one morning to realise you had forgotten to plug the car in and cannot get to work.
The battery is perfectly happy being daily topped up to 80% or so. Just do not charge all the way up to 100% on a regular basis.
The A2 is a very competent charger. My Zappi’s are just the same. I use their charge timers and ignore those in the car entirely.
If you set start and stop times on the charge point will it still respond to a manually activated (via the Tesla app) climate on and precondition in the morning even though that is outside the charge point set period?
In general, if the charge point is in complete control of charge times, and is not using the Tesla API at all, then ground power will only be available when the charge point is advertising that power is available. The car will not be able to tell the charger(s) to request power from the charge point if it's not actively set to charge, as they will sense that the charge point is not advertising, and will be effectively disabled.
I suspected that may be the case ... which is why I've never bothered to use the Zappi timer. I like to be able to initiate precondition and extra top up charges via the Tesla app at non-fixed times. I'll stick with the car start timer and hope that eventually we get a finish time too at some point.
I have been thinking about adding remote switching to it, just a simple remote that can switch the charge point between always on, always off or off-peak timed. That would allow preconditioning to use ground power, without me having to go out and flick the switch on the charge point. Not sure it's worth the hassle though.
My concern over third party apps using the unofficial Tesla API to control things is that you are effectively giving control of the car and your Tesla account to the app, by giving it your log in details.
I have the same set-up (with Ohme charger) and this works for me, I just plug the car in and it's charged in the morning.
Bob's your uncle...
- set car to start charging 00:30 with desired SOC
- Connect Ohme app to Tesla account to allow Ohme app to read SOC
- choose Octopus Go tarrif in Ohme app
- set 'never charge above 5p p/kWh' in Ohme app
- Create a charge schedule (mine is set to daily) with your desired end SOC to match car and finish time of 04:30. This allows the Ohme charge to calculate the charge time and warn you iif your desired SOC can't be achieved.
Hope that helps
When I got my EO Home Mini installed, it came with a little leaflet saying, if you have a model 3 and want to use scheduled charging then make sure you have sentry mode enabled, otherwise the car may go into deep sleep and not recognise that charge is available at the scheduled time.
Not got the car back yet to be able to play with it...I'm in two minds, I suppose another set of cameras on the driveway never hurts but I had every intention of leaving it switched off at home just to save power.
I set my 3LR up as above 2 nights ago (I have the Ohme charger and app):
- Car had a starting charge level of 35%
- Set car to start charging 00:30 with 82% as target SOC
- Connected Ohme app to Tesla account
- Chose Octopus Go Faster 00:30 - 04:30 tarrif in Ohme app
- Set to 'never charge above 5p p/kWh' in Ohme app
- Created a daily charge schedule with 82% SOC (to match car's SOC) with a finish time of 04:30
Initially the car started charging immediately that I configured the above (at about 8pm), so I went out and unplugged and re-plugged the charge cable and it correctly stopped charging (I only spotted it was doing this after about 40 minutes!). The car then correctly commenced charging at 00:30 and stopped at 04:30, having managed to get to 78% (so 4% under target SOC).
I left the car plugged in and I expected the car to start charging at 00:30 last night to add the additional 4% and then stop, but it looks like the car never woke up at all overnight and Teslamate is showing no record of any charge.
I never opened the Ohme app after initially configuring it - is this the issue (in that it needs to be running in the background to work), or am I missing something else?
That doesn't happen for me doing exactly the same as you... Might be worth emailing Ohme support, they're really helpful
I think it might have not picked up the daily cycle until the following day, as I went into the app last night and it was showing charge complete (theopretically as a one-off), and so I clicked start charge again and it then went into the correct holding patterns and topped up the remaining SOC and is still saying charging is taking place now (but is effectively paused until 00:30). Will see how it behaves over the next few days....
That's great, hopefully it solves the issue for you.
In case you are not aware, Octopus offer other 'Go' tarrif options as well. I have asked to go on the 5 hour one, starting at 20:30 for 5.5p per kW/h instead of 5p kW/h. I reckon using our washing machine, dryer and dishwasher during that time period will offset the extra 0.5p for the car charge. If you are interested you can email them and request an invitation to the 'beta' tarrifs.
