HAN P1 Serial adapter

A direct connection to a new smart HAN P1 enabled energy meter via the adapter enables almost real-time monitoring of your electricity consumption. Read more about HAN P1 Serial Adapter

Load management based on measured energy consumption

Consumption information can also be used to make so-called load management, i.e. Arska automatically switches off the devices it controls if the load of one or more phases exceeds the defined limit. In this way, it is possible to avoid blowing the main fuse or to reduce the power fees charged by the grid company. HAN P1 Serial is recommended energy meter type for load management. Read about the principles of Load Management.

More advanced channel rules user interface

A new operator select for following variables: "(7) 8 h block id", "(110) month", "(112) weekday", and "(115) hour". With the operator your can select one or more values in a condition.

If none of rule conditions match, channel is set to default state. In version 1.1 or later you can specify default state (up or down). In earlier versions default state was always down.

Standalone mode with no WiFi connection

Arska version 1.1 supports standalone mode without connection to your local WiFi network if the MCU is connected to a HAN P1 enabled energy meter with a serial adapter. Because the standalone mode there is no internet connection, so rule variables based on price and forecast data are not supported. But rule variables based on data from the energy meter, i.e. current consumption and time/date are available.

Arska version 1.1 is currently in beta status (12.12.2023)
