Buy prices for DESS not working with quarter hour intervals

Hi everyone,

I’m not using the dynamic prices option for my country because I need to apply custom formulas depending on the time of day.

When I manually fill in the DESS prices, everything works fine with hourly or half-hourly intervals — the prices are applied correctly, and the graphs look as expected.

However, when I switch to quarter-hour intervals, the DESS prices don’t work properly anymore. The graphs become messed up and don’t match the prices I’ve entered.

I’m writing here to ask if anyone else has noticed this issue and if it’s already been reported as a bug.

Thanks!

I am having issue when i set quaterly hour prices with Tibber in the netherlands that the buy and sell pricediffer. It looks like on VRM sell price is still hourly but buy price is quaterly. It makes DESS behave strange. Should i change the formula. Please help.

For example, I can only set fixed prices every half hour or each hour. If I try to set fixed prices for the entire day in quarter-hour intervals, the VRM gets completely messed up like you said. I think it imports hourly prices instead of quarter-hour prices.

Sorry my mistake. I needed to set 15min in both buy and sell
