Price data
Entso-E API key for price data
Day-ahead price data is fetched from transparency.entsoe.eu, a service operated by Entso-E. Entso-E is an association of European association grid operators. Elering is a backup price data source for EE, FI, LV and LT.
To read data from Entso-E transparency API you need a free API key. To get a key:
- Register first on the ENTSO-E transparency platform
- Request an API key by sending an email to [email protected] (press this link) with “Restful API access” in the subject line. In the email, state your registered email address. You will receive an email when you have been provided with the API key. Enter the new API key to the field "EntsoE API key". If you control multiple devices you can use the same key on all devices. See Entso-E documentation: How to get security token?
Area code
Set your price area from the list of available price areas. Some European are divided into multiple price areas.
Price modifier
Price modifier allows you can for example set negative modifier for night time hours when the transmission cost is lower. Modified priced are used in all calculations, ranks. and grahs etc. Clear price cache and restart after the change.
Energy Forecast
Open Meteo based solar energy forecast requires location coordinates and panel setup (tilt+azimuth). FMI solar forecast is available in Finland only and is calculated in selected locations with a model panel setup (tilt 30°, South).
Panel peak power (W)
Panel peak power in watts to scale solar forecast. (Open Meteo and FMI)
Daytime baseload (W)
Estimated daytime baseload (consumption) in watts. This is used to estimate solar "overproduction" if metering is not available. (Open Meteo and FMI)
Open Meteo Settings
Latitude
Latitude of panel location (-90° - 90°).
Longitude
Longitude of panel location (-180° - 180°). You can get latitude and longitude for example by clocking your location on Google Maps.
Declination/Tilt
Declination/Tilt of the panels, 0° horizontal - 90° vertical (wall install).
Azimuth
Azimuth refers to the direction the panels face, measured in degrees clockwise from true north, 0° south, -90° east, 90° west.
FMI Settings
Forecast location
Select the nearest available location for 24 hours solar power forecast.
Grid Energy Metering
Optional grid metering helps in optimising the use of self-produced electricity. Requires supported energy meter.
Energy Meter Type
- HAN P1 Serial (adapter)
- HAN P1 Proxy (HomeWizard P1 Meter or another Arska device with HAN P1 Serial)
- Shelly 3 EM energy meter
GPIO (RXD)
GPIO number of the serial input (HAN P1 Serial only)
IP Address
IP address of a Wifi connected meter/proxy
IP Port
Typically 80 for Shelly 3 EM and HAN P1 Proxy
Energy Meter Password
Optional password of the energy meter. (Shelly 3EM only)
Read about energy meter configuration
Energy Production Metering
Optional production metering reads your solar inverter.
Inverter Type
Some SMA and Fronius models supported.
Inverter IP Address
IP address of the inverter
Inverter IP Port
Typically 80 for Fronius, and 503 for SMA
Inverter IP ID
Typically 3 for SMA ModBus.
Load Management
Load management available is from version 1.1. Read about the principles of Load Management.
Load Management active
Phase Count
Choose how many phases there are in your electricity connection, 1 or 3
Max Phase Current (A)
Maximum allowed current per phase, e.g. 25 if the main fuses are 25A. ###Max total power (kW) Maximum allowed power (15 min/1 h period average)
Re-switch wait time (minutes)
How long time system wait before re-switching loads after overload.
InfluxDb Server
Define optional server for history time series reporting and analysis. InfluxDB is an open-source time-series database where Arska can store history data for reporting and analysis. See instructions
Localisation
Change time zone and language. The program is mainly showing English texts regardless of your choice but there are some Finnish instructions on the channel templates.
Network
Change WiFi network and password here. Refresh the list of wifi networks with 🔁 button.
Change default password arska (user id is admin) here to your own secret password. Until you have done it, the admin page is automatically opened with the warning. To change admin password type in in the both fields. Please note that this is only an additional protection for your Arska device. Protect your local network with a proper router firewall and other appropriate measures.
System administration
Backup and restore
Backup configuration
Download current settings to a file. Take a backup always before system update.
Restore configuration
Upload settings from a file on your computer. Could be used e.g. if settings are cleared in a system update.
System Update
