Firstly I am pleased to see in the UK the API to Octopus down loads the schedule and costs. DESS produces a perfect schedule for max discharge of my batteries between 16:00 to 19:00 ok. It’s also controls selling during the day with enough time to charge the batteries to 85% pre the discharge timings. 
When it starts the 16:00 to 19:00 discharge it does not keep a consistent discharge rate, any ideas why?
When finishing discharging ( 16:00 to 19:00 ) it switches to buying in power to charge the battery ( not at full charge rate ) when the battery is at 48%, any ideas why?
This mainly happens, because your SoC is dropping faster, than it should based on the amount that is discharged. There are a variety of reasons why this may happen, but in the most recent beta, we made a small change in behaviour there (switching to only support loads over buying or idling), you should try that out.
How do I check my DESS version and if applicable how do I reload any Beta version of DESS?
It’s just included in the regular VenusOS Version.
You can switch the Update Feed between Release and beta Versions.
The system keeps your previous version as an image as well, so when you encounter any beta-related issues, you can switch back to the prior version with one click.
Does is the beta swap start here?
You best do that in the cerbo ui:
Settings → General → Firmware
By that chance, just upgrading from your 3.54 to 3.62 will also bring you a variety of general DESS improvements. 3.70~6 then adds another tiny improvement as mentioned above.
Thanks for the help, I upgraded to 3.62 but can not see 3.70~6 as an available upload. I’m showing no uploads available.
For that, you would need to set the Update Feed to Beta, and then checl for updates again.
dognose - A big thank you for your help on the firmware update. It’s a joy to watch it behaving its self now. I’m currently away from home so the load is very low. When we get home I can report back on how it handles daily power use.
