Shelly Electricity Tariff API
Live electricity prices on every Shelly device via Shelly Cloud's Electricity Tariff API — no Python scripts, no Home Assistant, no LAN proxy. Paste one URL into Elewatt and the all-in price refreshes every 15 minutes, automatically.
The easiest way to power your Shelly Electricity Tariff
Other guides ask you to deploy a script, run a server, or babysit a Home Assistant add-on. Elewatt drives Shelly Cloud's official Electricity Tariff API for you: copy the API URL from Shelly Cloud → Energy → Electricity Tariff, paste it into Elewatt, pick the contract you want pricing from, and your Live tariff updates natively on the device — every 15 minutes, in your home currency, including grid fees and VAT. No code. No maintenance. No API key from you.

Add your electricity contract
In Elewatt, go to Contracts and add your tariff: country and price area, grid fee, day/night tariff if relevant, and VAT. This is what we use to calculate the all-in price your Shelly device will show. Stock-price contract? We add the supplier margin too.
Get your Shelly Electricity Tariff API URL
In Shelly Cloud (cloud.shelly.com), open Energy → Electricity Tariff, switch the tariff to Live, and copy the API URL at the bottom of the panel. It looks like https://shelly-XX-eu.shelly.cloud/v2/users/.../… — this is the only thing Elewatt needs to push prices to your account. No API key, no OAuth.
Paste the API URL into Elewatt → Integrations
In Elewatt, go to Integrations → Shelly Cloud → Electricity Tariff API. Paste the API URL, pick which contract's pricing should be sent, and click Save. Optionally hit "Push price now" to send the current price right away — handy for a quick smoke test.
Verify the live price on your Shelly device
Open the Shelly Smart Control app or your Shelly Cloud dashboard and head back to Energy → Electricity Tariff. Within 15 minutes you should see the Live tariff update with the latest all-in price. From there, build any logic you want on the Shelly side — turn the relay on under a price threshold, run a script that triggers on cheap hours, or just display it. Elewatt keeps the tariff fresh every 15 minutes, automatically.
