PörssÀri
Devices & Services > PörssÀri reads PörssÀri's own control-schedule API for one configured device - a Finnish service that computes an on/off/boost relay schedule for up to 8 channels, based on Nord Pool spot prices and rules you configure on porssari.fi itself.
Adding a device
Generate a "PörssÀri laitetunnus" (device id, looks like HA1234567890AB) on
porssari.fi by adding a "Home Assistant" device there under your own account - that's the only
credential this integration needs, entered once when you add the device here.
Entities
Eight read-only sensors, Channel 1 through Channel 8. Each one's value
is whatever number porssari.fi computed for that channel - 0/1 in a
channel's own "normal mode" or 10/20/30
(off/normal/boost) in "heating mode", and -1 for a channel with nothing configured
on porssari.fi at all. Which mode a channel is in is set on porssari.fi's own side, not something
this integration can label for you - build automations against whatever scale your own channels
actually use.
A background loop polls every ~5 minutes, matching the cadence PörssÀri's own official Home Assistant client uses, and only records a change when a channel's own resolved value actually moves.
Works with Dashboard cards, History, and Automations exactly like every other integration - there's nothing to control, so it never appears as an Action node target, only as a state source.
