How to set it up
From a paired Daikin to automatic cheap-hour heating in 5 simple steps. Takes about 15 minutes.
Set up your Daikin heat pump in the Onecta app
Download the Daikin Onecta app (iOS or Android) and follow the in-app pairing wizard to connect your heat pump to your home Wi-Fi. Make sure to assign it a name you'll recognise (e.g. 'Heat Pump') and confirm that you can see live status and adjust temperatures from the app.
Create a Contract and Price Filter in Elewatt
In Elewatt, go to Contracts and add your electricity tariff. Then go to Filters and create a new price filter — this defines when you want the heat pump to run based on the electricity spot price or the cheapest hours of the day.
Authenticate with Daikin Onecta
In Elewatt, go to Integrations → Daikin Onecta and click Connect. You'll be redirected to Daikin to sign in with your Onecta account and authorise Elewatt. After approval you'll be sent back to Elewatt — your paired heat pump will appear in the device list automatically.
Link your Daikin to the price filter
In Elewatt under Integrations → Daikin Onecta, find your heat pump and select the price filter you created. Elewatt will now calculate the optimal on/off schedule each day based on tomorrow's electricity prices and push it to the device through the Onecta cloud.
