I’ve spent a bit of time setting up a Node-RED flow to import prices from my (unsupported) local provider in Australia - Amber Electric - using their API. With thanks to @dfaber ’s post and @podarok ’s contribution also, I’m feeding the provider’s prices into Dynamic ESS successfully: // Extract the …

Hi Andrew, I am running in Trade mode but have not really let DESS do anything yet. I am just running ESS with DESS off. My house has 3 phase supplied but I have 2 x Multiplus 5000 and the third phase has Oven and Ducted aircond on it. Basically lighting is on phase 2 and power on phase 1. …

I wonder if the weird behaviour with the prices/graphs is to do with DESS being switched off? :thinking: Sounds like we’ve been on similar journeys! I’ve got self-built 15kWh batteries using “DIY” kits from Alibaba - 280Ah EVE cells, 200A JK Inverter BMS in a nice metal chassis. We have a weird (fo…

Hahaha…DESS just failed its first test. We have negative feed in pricing currently, -4 c/kWh and DESS decided to ramp my feed in to maximum…Oh well…may have to think a bit more about this…

Yes, I’ve been having that exact problem – I’ve tried feeding this back to Victron, but haven’t really got to the bottom of it yet. It still doesn’t really know what to do with negative prices! Green mode seems to be a bit better here, but still. It’d be great if the Victron staff could be a bit mo…

Hi @ndrew , I am trying to implement a speculative price forecast flow in node red that extends the know price range (array) by 12 or more hours and fill those (not yet published) prices with the last/latest known price. Reason is that DESS refuses to start charging early in the day because it ass…

Jan, I apologise for the slow reply – acknowledging your question and work, I will do some further digging, but I believe you (and me) are coming up against some limitations of the DESS implementation. I think I will shortly need to start looking at locally-managed solutions (EMHASS looks promising,…

Hi All I’ve imported the flow from the gist above and think I have updated all the various SiteIDs + API tokens for both VRM and Amber. It looks like I’m successfully retrieving the prices from Amber. I’m currently getting an error when attempting to update the DESS prices. “Error fetching VRM da…

G’day, Greg. This occurs secondary to Amber’s recent-ish change to 5-minute billing. DESS only supports 30-minute increments. I fixed this locally when it first happened but didn’t think to update the Gist . I’ve done that now. Thanks for the reminder! :slight_smile: It’s probably just as easy to u…

Hi Andrew Ah gotcha, great pickup. I’ve made that change but still have an error on the vrm-api node. I’m still getting the “Error fetching VRM data” and in the debug log: {“url”:“``https://vrmapi.victronenergy.com/v2/installations/483236/dynamic-ess-settings?",“options”:{},“headers”:{“X-Authoriz…
