shelly-elpris-dk-no is a Shelly script for controlling outputs based on Nord Pool spot prices in Denmark (DK1-DK2) and Norway (NO1-NO5).
The project is a regional adaptation of shelly-elprisSE, which itself is based on shelly-porssisahko v3.1.1 by Jussi Isotalo.
Version 3.1.5 shares the same internal architecture and logic as the SE release, but uses Danish and Norwegian price APIs and regional settings.

-- = Not tested , SI = Shows instability
Shelly Gen 3-4: - may work, - not fully tested
- memory constraints may cause instability
- Unified DK + NO support
Single build with automatic zone detection and correct API routing. - Improved UI
Refined Status, History, Setup and integrated Help tab. - Grid fee model
Clear weekday/weekend separation and time-of-day detection (where applicable). - Improved reliability
Fixes for day rollover, VAT calculation, override persistence and spot price display. - Optional H&T temperature addon
Dynamic adjustment of cheapest hours based on Shelly H&T sensor data.
Prices are fetched via regional APIs and delivered in a compact, Shelly-friendly format:
At the time of writing, both APIs provide hourly (24-interval) price data.
The script parses and operates on this format directly, without any internal aggregation.
The current implementation will continue to work as long as the APIs keep delivering 24-hour data.
If either API switches to 15-minute intervals in the future, the script will stop working until a new version is released that is adapted to the updated API format.
No transition date for such a change is currently known.
- Connect your Shelly device to the network.
- Update firmware to latest stable (>= 1.7.x recommended).
- Set timezone:
- Europe/Copenhagen (DK)
- Europe/Oslo (NO)
- Create a new script in Shelly Web UI.
- Paste the latest shelly-elpris-dk-no.js (ver. 3.1.5) build and save.
- Start the script and open the console.
You will see output similar to:
elpris: v.3.1.5_12
elpris: URL http://192.168.8.119/script/1
- Open the HTTP endpoint shown in the console.
Note:
/script/Ndepends on the script slot used on your device.
The Shelly device exposes a lightweight HTTP UI with four tabs:
| Tab | Description |
|---|---|
| Status | Current state, prices, outputs and active logic |
| History | Logged actions and state changes |
| Setup | Zone, VAT, tariffs, outputs and overrides |
| Help | Embedded documentation and usage notes |
- KVS structure changed in 3.1.5
Configuration slot #3 was removed. Old KVS keys from earlier versions should be deleted before first start. - The script assumes hour-based control logic though price input is 24-hour based.
An optional addon script can be loaded after the main script.
It uses temperature data from a Shelly H&T sensor to dynamically adjust the number of cheapest hours.
Addon documentation and examples are located in the SE addons/ directory.

The public repository contains ready-to-use builds only.
Internal build tooling, sources and npm-based environment are currently not public.
Forks, adaptations or collaboration can be discussed via GitHub Issues.
Keeping the proxy infrastructure and APIs online costs time and money.
