PELS
Capacity guard predicts hourly hard-cap budget breach; manual action required
PELS
Save energy and money with automatic capacity control and price-aware load shifting.
Warning! This app might not work properly.
This app version is currently being tested, and has not yet been reviewed. It might not work as expected.
Be extra careful when installing this app.
PELS (Pris- og Effektstyrt Energilagringssystem) helps you optimize energy usage in your home by managing when your largest energy consumers run. It keeps you within your power limits by intelligently shedding load from lower-priority devices when consumption approaches your limit, then restores them when headroom is available. It also supports price-based control using Norwegian spot prices and grid tariffs (with either strømstøtte or Norgespris model), Homey Energy dynamic prices, or external flow tag prices (Power by the Hour or similar) when you prefer external price feeds.
Set your capacity limit, assign priorities to your thermostats, water heaters, and supported EV chargers, and let PELS handle the rest. You can define different modes like Home, Away, or Night, each with their own temperature targets and priorities, and switch between them through Flows or the built-in PELS Insights device. Experimental EV charger support is available for official Homey EV chargers when enabled in Advanced settings.
Inspired by the Sparegris (Piggy Bank) Homey app.

When...
Triggers when PELS projects that the hourly hard-cap budget will be breached at the current run rate and there are no controllable devices left to shed. This is an emergency situation requiring immediate manual intervention. Note: This only triggers for hourly hard-cap budget breaches, never for daily budget soft-limit violations.
PELS
Desired stepped load changed for Device
Triggers when PELS wants a stepped-load device to move to another configured step.
PELS
Operating mode changed to Operating mode
Use this to trigger flows when PELS switches to a different operating mode.
PELS
Price level changed to Price level
PELS
Current price is one of Lowest count lowest in the Hours hours before End hour:00
PELS
Current price is one of Lowest count lowest prices today
And...
PELS
Is there enough headroom for Required power (kW) kW?
Use this to check if current headroom is enough to add the requested load.
PELS
Does Device have headroom for Required power (kW) kW?
Checks if the current headroom plus the device's estimated usage is enough to add the requested load. Built-in hysteresis keeps this false for about 60 seconds after a meaningful step-down or recent PELS control on the same device, and repeated failed re-activations require extra headroom before it turns true again.
PELS
Operating mode is Mode
Use this to create flows that only run when PELS is in a specific mode (e.g., Home, Away, Night).
PELS
Device has budget exemption
Use this to check if the selected device is ignored by daily budget soft-limit control while still counting in real usage and capacity management.
PELS
Is Device capacity controlled?
Use this to check if PELS can shed or restore the selected device based on capacity limits.
PELS
Is Device managed by PELS?
Use this to check if PELS is currently managing the selected device.
PELS
Price level is Price level
PELS
Current price is one of Lowest count lowest in the Hours hours before End hour:00
PELS
Current price is one of Lowest count lowest prices today
Then...
PELS
Add budget exemption for Device
Exclude this device from daily budget soft-limit control. Real usage still counts in charts and budget reporting, and capacity management still applies.
PELS
Disable capacity control for Device
Keep PELS from shedding or restoring this device while capacity control is disabled.
PELS
Enable capacity control for Device
Allow PELS to shed or restore this device based on capacity limits.
PELS
Remove budget exemption for Device
Make this device follow daily budget soft-limit control again. Capacity management is unchanged.
PELS
Report power Power (W) W
Feed instantaneous power (W) from a meter to track hourly energy usage and feed capacity guard.
PELS
Report stepped load for Device as Step
Use this after a vendor-specific action card, or when the device changes step outside PELS, so PELS knows which configured step is currently selected.
PELS
Report stepped load for Device matching Power
Use this when a device app gives you a power value instead of a step name. PELS matches the configured step by planning power. Accepts values like 1750 or 1750 W.
PELS
Set capacity limit to Limit (kW) kW
Use this to dynamically adjust your power limit based on time of day, electricity prices, or other conditions.
PELS
Set operating mode to Mode (e.g. home, away, vacation)
Use this to automatically switch PELS modes based on time, presence, or other triggers in your flows.
PELS
Set daily budget to Budget (kWh) kWh
Use this to adjust your daily energy budget from flows. Set to 0 to disable the daily budget.
PELS
Set external prices for today from Price data (JSON)
Paste the price JSON from Power by the Hour's "price changed" card tag. Single quotes are accepted (e.g., {'0':0.2747,'1':0.2678,...}).
PELS
Set external prices for tomorrow from Price data (JSON)
Paste the price JSON from Power by the Hour's "price changed" card tag. Single quotes are accepted (e.g., {'0':0.2747,'1':0.2678,'2':0.261,...}).
