Spot Scheduler
Take control of your electricity costs
Spot Scheduler helps you save money by running your devices when electricity is cheapest. With quarter-hour prices in real-time, you can automatically charge your EV, run the washing machine, or heat your water during the lowest prices of the day.
Supports all Swedish electricity areas (SE1-SE4). No API key or subscription required.

Electricity Price Sensor
The Number of cheapest periods cheapest periods fall between From (HH:MM) and To (HH:MM)
Use this to check if today's cheapest periods happen to fall within your preferred time window. Helpful for deciding whether to run a device now or wait for a better opportunity.
Electricity Price Sensor
It is among the Cheapest periods cheapest periods (Cheap period from (HH:MM)-Cheap period to (HH:MM)) AND at least Min price diff (kr/kWh) kr/kWh cheaper than the Expensive periods most expensive periods (Expensive period from (HH:MM)-Expensive period to (HH:MM))
Advanced condition for battery charging optimization. Checks if you're in a cheap period AND the price spread to expensive periods is large enough to justify charging. Use this to only charge batteries when there's significant savings potential.
Electricity Price Sensor
It is now among the Expensive periods (discharge) most expensive periods (Discharge period from (HH:MM)-Discharge period to (HH:MM)), with at least Min price diff (kr/kWh) kr/kWh higher than the Cheapest periods (charge) cheapest (Charge period from (HH:MM)-Charge period to (HH:MM))
Use this for battery arbitrage - selling stored energy during expensive periods. Triggers when you're in an expensive period AND the price spread vs cheap charging periods meets your minimum threshold. Set spread to cover battery losses (typically 0.20-0.50 kr/kWh for round-trip efficiency).
Electricity Price Sensor
Average price for coming Hours ahead hours is below Max average (öre/kWh) öre/kWh
Check if the average electricity price for the coming X hours is below a threshold. Useful for deciding when to run devices based on upcoming price trends.
Electricity Price Sensor
The Periods to compare cheapest periods today (Today from (HH:MM)-Today to (HH:MM)) are cheaper than tomorrow (Tomorrow from (HH:MM)-Tomorrow to (HH:MM))
Use this to decide between running a device today or waiting until tomorrow. Compares specific time windows across days. Perfect for flexible loads where you can choose which day to run - only run today if it's actually cheaper than tomorrow.
Electricity Price Sensor
It is now within the cheapest Consecutive periods consecutive periods in the next Within hours hours
Use this for devices requiring uninterrupted runtime with a forward-looking horizon. Unlike the time-window version, this looks ahead from now. Perfect for starting a 2-hour wash cycle during the cheapest consecutive block in the next 12 hours.
Electricity Price Sensor
The price is among the Number of cheapest periods cheapest periods before Before (HH:MM)
Use this when something must be done before a deadline. Perfect for ensuring EV is charged before you leave for work, or water is heated before morning showers.
Electricity Price Sensor
It is now within the cheapest Period length (minutes)-minute period between From (HH:MM) and To (HH:MM)
Use this for devices that need to run continuously for a specific duration. Perfect for washing machines, dryers, or any appliance that must complete a full cycle without interruption.
Electricity Price Sensor
The current price is among the Number of cheapest periods cheapest 15-min periods today
Use this to run devices during the cheapest periods of the day. Great for flexible loads like water heaters, EV charging, or dishwashers that can run anytime during the day.
Electricity Price Sensor
The price is among the Number of cheapest periods cheapest periods in the next Within hours hours
Use this for forward-looking optimization across multiple days. Unlike the daily version, this looks ahead a specific number of hours (up to 48h when tomorrow's prices are available). Great for longer-term planning.
Electricity Price Sensor
The price is among the Number of cheapest periods cheapest periods between From (HH:MM) and To (HH:MM)
Use this to find cheap periods within a specific time window. Perfect for devices that must run during certain hours, like charging an EV overnight (22:00-06:00) or running a pool pump during daytime.
Electricity Price Sensor
The price is among the Expensive periods most expensive periods, but NOT in the Exclude top expensive most expensive
Use this to identify 'moderately expensive' periods while excluding the absolute peaks. Useful for gradual load reduction - reduce some loads in this band, and reduce more during peak periods.
Electricity Price Sensor
The price is among the Number of expensive periods most expensive periods before Before (HH:MM)
Use this to identify expensive periods that occur before a specific time. Useful for avoiding morning peak prices before work, or detecting when to delay device usage.
Electricity Price Sensor
It is now within the most expensive Period length (minutes)-minute period between From (HH:MM) and To (HH:MM)
Use this to detect when you're in a continuous expensive period. Good for reducing power consumption or switching to battery/backup power during extended high-price periods.
Electricity Price Sensor
The current price is among the Number of expensive periods most expensive 15-min periods today
Use this to avoid running devices during peak price hours. Great for temporarily pausing non-essential loads or switching to battery/solar power during expensive periods.
Electricity Price Sensor
The price is among the Number of expensive periods most expensive periods between From (HH:MM) and To (HH:MM)
Use this to identify the most expensive periods within a specific time window. Useful for avoiding peak prices during typical high-demand hours like mornings (06:00-09:00) or evenings (17:00-20:00).
Electricity Price Sensor
It is optimal to charge Energy needed (kWh) kWh at Charging power (kW) kW before Ready by (HH:MM) (Mode)
Calculates the cheapest time slots to charge a specific amount of energy before a deadline. Returns true when you're in one of the optimal periods. Choose 'Cheapest quarters' for maximum savings (may have gaps) or 'Continuous period' for uninterrupted charging.
Electricity Price Sensor
The electricity price is at least Percent above average% above today's average
Use this to detect when prices are significantly above average. Good for triggering power-saving modes or switching to alternative energy sources during relatively expensive periods.
Electricity Price Sensor
The electricity price is at least Percent below average% below today's average
Use this for a relative price comparison that adapts to daily conditions. Great when you want to run devices during 'good' price periods without setting a fixed threshold that may not suit all days.
Electricity Price Sensor
The electricity price is below Max price (öre/kWh) öre/kWh
Use this when you have a specific price limit in mind. Ideal for setting a maximum price you're willing to pay, regardless of daily price fluctuations.
Electricity Price Sensor
The price is at least Percent below average% below the average for the next Coming hours hours
Use this for forward-looking relative comparison. Checks if the current price is significantly below the average of upcoming hours. Great for detecting good buying opportunities when prices are expected to rise.
Electricity Price Sensor
The electricity price is negative (below 0)
Triggers when electricity prices go below zero. This happens during high wind/solar production when there's excess power. Perfect for running heavy loads for free (or getting paid to consume)!
Electricity Price Sensor
Price difference in next Periods ahead periods is at most Max difference (kr/kWh) kr/kWh
Use this to check if upcoming prices are stable. When true, there's little benefit in waiting for a better price. When false (high variation), it may be worth delaying consumption to a cheaper upcoming period.
Electricity Price Sensor
Today's price difference (high-low) is at most Max difference (kr/kWh) kr/kWh
Use this to detect 'flat' price days where timing doesn't matter much. When price variation is low, you can run devices anytime without significant cost difference. Also useful for disabling complex scheduling on stable-price days.
