Start when electricity is cheap, stop when expensive
. The cheap-expensive trigger works just
like the "keep on" trigger, but uses two price limits. Appliances are not switched OFF at the
crossing the cheap limit but only after the price goes above the expensive limit.
Each price trigger also has custom settings that let you further customize exactly when the trigger
turns on
•
Custom price limit
. If you don't like the system-wide limit for cheap electricity, tick the box for
custom limit and set a fixed price limit for cheap electricity.
•
Minimum ON time
. This is the minimum time, in hours, the appliance should be on for the trigger
to activate. For instance, if you tariff control a washing machine, you may want to set this limit
to make sure the machine runs its program in full before power is shut down. If you use a trigger
that cuts power at price limits, this setting will make the trigger look for slots where electricity
price is below the set cheap limit for the whole duration of the period.
•
Minimum total time
. The minimum time per day the appliance should be on. This setting partly
overrides the price limits. If you for instance specify that an appliance must be on for a minimum
of five hours daily, the automation will look for slots where prices are low compared to daily
average and chooses enough to make sure them minimum time is fulfilled. Note that these slots
are not necessarily sequential.
•
Maximum total time
. The opposite of minimum time. No matter how cheap electricity is, this
setting ensures that an appliance cannot be left on for more than this amount of hours per day.
Price triggers can be used to automatically switch on and off appliances and themes, based on
the current electricity price. For example: the water heater can be switched on when the price is
low, rather than directly after using it.
The Asema E system takes the electricity price from Nordpool Spot Power Market
(www.nordpoolspot.com) as a reference. Of course, this will only affect your electricity bill if your
utility bills you according to the hourly prices of the Nordpool Spot Power Market. Contact your local
utility about the possibilities. You can always check the current price from the Nordpool screenlet.
