Q&A and troubleshooting DESS

I curious to where DESS is running and where the data it usses is retrieved and processed.

Are the pricing and solar/weather forecasts downloaded, and are calculations/forecast produced on the cerbo (venus) or is this all done in the Victron ‘cloud’?

Using Node-red, I can conenct via victronenery.com, but also to venus.local (so directlry connect to the cerbo). But when I use the VRM api node to get the installations stats for instace, are they retrieved directly from the cerbo or will it go out to the victron site?

Put in another way, if my internet connection is down, will DESS still be able to manage battery infrastruture?

Hi,

DESS Forecasting and scheduling is done in the cloud and frequently send to the device. It stores the schedule for upto 12h, so in case of a loss of connectivity it could stick to plan.

After that, it will just switch to regular ESS Behaviour, until commectivity is restored.

Thanks dognose for explaining!

Does that also mean that node-red flows will be ‘blocked’ when internet is down?
