I installed OTA update 1.3.1 yesterday.
I wish I had not.
Things have got far worse with it.
I have an OHME Home Pro charger which cannot link to the Volvo EX30 due to an API issue. As a result I have to depend on the EX30 internal timer to charge during my electricity suppliers off-peak rate (0200-0900).
With software 1.2 things worked fine (I had an issue with the clock changing the time all by itself, but that has been resolved by setting it manually not automatically by Vodafone.)
Last night I updated to 1.3.1.
Then at 1900 I plugged in for the usual off-peak rate charge starting at 0200. I happened to wake up at 0300 and noticed the car hadn't started charging as it should. Fortunately I was able to start it charging manually, and was able to use the car.
Then at 1700 I plugged in for the usual off-peak rate charge starting at 0200. At 1900 I noticed that the car was charging, even though the app clearly showed that it shouldn't be as it was timed for 0200-0900. I was able to stop the charge - but only after putting in 11.6 kh of peak rate electricity!
Update 1.3.1 has stopped charging timer working
Not tried it on this new 1.31 with it yet.
I use the car timer for top up by using 3 pin 13 amp charger. It's set for 11:30 pm to 05:30 to use my cheap rate whilst in the garage. OHME Charger is outside in drive.
May be fun next time.

/YELLOW/MIST TWIN MOTOR ULTRA v1.4I was using the Volvo timer as it could guarantee that the charger would deliver charge to the car for a full 7 hours from exactly 0200 to 0900, getting up to 49kWh (probably more like 45 kWh as it fluctuates between 6.8 and 7 kW during charging) during the 7 hour off-peak-rate.
With the OHME app, you have to set a finish time (0900 in my case) and use trial and error to guess the % requested to get a start time at 0200.
I have now done that, and have set a figure of 50% by 0900, which OHME has calculated to start charging at 0208, which should be fine.
50% is less than 35kWh, which is a lot less than the 45kWh that should go in during a 7 hour charging session. As I am already at 50%, this should be OK, but if the charge remaiining was lower, this could be an issue. However as OHME still can't talk to the EX30 because of the lack of API data, hopefully it will just keep charging to 0900 (or the 90% capacity that I have set in the car) when needed.
I have emailed Volvo support. It will be interesting to see what they say. Hopefully this bug will be fixed in the next OTA update - whenever that will be!

Since OTA update 1.3.1, my EX30s charging schedule timer has not worked properly (preciously it worked perfectly).
I set the OHME Home Pro to charge between 0208 and 0900. The Volvo time remained set at 0200 to 0900.
At 0230 I checked the car . It was not charging. It was showing that it was scheduled to charge, but it was not accepting any of the power OHME was trying to send it.
I switched off the Volvo timer and it started to charge OK using the OHME setting.
I have now done some experimenting and believe I have got to the bottom of the issue.
It appears that there is a software bug in update 1.3.1 that has reversed the pilarity of the timer. The car will now not charge in the set charging schedule timings under any circumstances. It will however, charge at any time it is plugged in to an active charger outside the set charging schedule times.
I have been able to record error this on a video and taken photos of the EX30 screen and screenshots from the app, which I have sent to Volvo for their attention.
In the meantime, the simple work-round is to set the Volvo timer to the tine you don't want to charge.
ie - if you want to charge in the period 0200-0900, set the timer to charge in the period 0900-0200 instead.

On a different angle I have recently had an Ohme Home Pro installed. Only used it once and basically said add 70% during Octopus off peak charging.
This then “filled” the car by about 0630 although I didn’t go to the car until about 0800 and the ex30 reported filly charged.
So my question is if I use this approach 1) does the ex30 stop pulling charge when it gets to 100% or 90% if I set it to that, 2) does the Ohme stop pushing charge when the car is “full” and 3) will this damage either charger or car?
TIA

The car will stop charging when it reaches the capacity you specify. No damage will be caused leaving it plugged in after that. The OHME doesn't "push" electricity to the car, it just offers electricity to the car to "pull".

I thought I had it sorted after I proved on video that my car charged when it wasn't supposed to, but not when it was supposed to. But that was last night and this morning.
Tonight it proved me wrong. It doesn't know what it is doing, and I don't either.
I got home today and plugged it in. It was set to charge now, not 8 hours later, so I thought it wouldn't - but it started charging in accordance with what was scheduled. Then I changed the timer and set it not to charge now, but 8 hours later - 30 minutes later it started charging - when it was scheduled not to be charging.
I give up on Volvo's charging timer software. I will just use my chargers rudimentary timer instead.
My one thought is, if Volvo can't get a simple timer right, how do they get all the safety tech right?

Volvo have just got back to me about this issue.
They say that they can confirm that after the latest software update, there is a known issue to Volvo Cars which affects scheduled charging. They also add "We hope to resolve this in a future update, and at the moment I would advise continuing with your workaround [using the charger's timer, not the car's] as we currently do not have a fix for this."
Sometime then. OK I suppose, unless you are one of those who don't have a charger with a timer - in which case it is very bad news if you use night-time cheap rate charging.
