Re: Mode schduler force charge problem; plus conflict with ev charger?
Just following up on this. I raised a ticket with Fox on 7 May but have had no response. Does it usually take them this long? Seems like a fairly straightforward request.
Thanks again
Luke

Re: Mode schduler force charge problem; plus conflict with ev charger?
Many thanks Dave. My firmware definitely needs an upgrade I'm on 1.27 (master), 1.01 (slave) and 1.19 (manager). I'll raise a ticket today.
Also, apologies for posting this on the wrong section! Can't even claim a rookie error for that one

Mode schduler force charge problem; plus conflict with ev charger?
Hi everyone. I'm looking for some advice - again! I've had my system since August 24 (spec below) and am generally delighted with it.
I haven't bothered using the mode scheduler until recently, mostly because we're quite high energy users and we generally hit 10% before the day is out. So up until ...

Re: Load and PV data error, plus battery won’t charge
Hi Dave,
Thanks as always for your help with this - Will's video has enabled me to fix the issue. Much appreciated!
Also, your point about poor Wi-Fi signal and demand on the inverter is interesting. I have had lots of problems trying to charge the batteries through the mode scheduler - it ...

Load and PV data error, plus battery won’t charge
Help! Both my fox and energy stats apps are showing some absurd data around load and PV. The desktop version is also showing the wrong data, and this has been happening since about 1:30 this afternoon. I took the screen shots at around 8:30 this evening.
As well as seeing the wrong data, I am also ...

Ah I see! Thanks so much Dave - should have checked that first.

Switched to 2.5ghz WiFi - broke Energy Stats?
Hi. I temporarily deactivated 5ghz WiFi so I could set up some smart bulbs. When I switched back to 5ghz I was logged out of energy stats - and I can’t get back in.
I’ve tried copying the API key from Fox ESS about 6 times - just as when I first set it up - but just get the ‘could

Re: Batteries won’t charge
Ah thank you so much Dave! I’m *still* waiting for DNO approval, so just making sure I’m all set when it does actually come through.

Batteries won’t charge
IMG_1042.jpeg IMG_1045.png Hello. I keep seeing ‘write failure’ whenever I try and schedule a charge on my battery (see second attachment). I also have the energy stats app. When I try it from there it shows a ‘44098 write failure’ (see first attachment).

Re: Hello from Cambridgeshire
Many thanks again Dave. I tried the ‘simple’ method in the end and got it working.
I’m still awaiting my DNO approval, but once I have that I’ll get on a solar-friendly octopus tariff and start playing around with the mode scheduler.
I’ve also set the min socs to 10% based on your reassurance ...

Re: Hello from Cambridgeshire
Thanks so much Dave - I have actually set the mode scheduler for tonight, but will stick with the simpler version and make sure that charge from grid is enabled.
With the minsoc, do you set both the ‘battery reserve capacity’ and ‘system min SOC’ at 10%? I did that the other night and it went all ...
