The Instellingen relais (relay settings) page with the OFF/ON/AUTO switches.
Smart relays let the system automatically switch an appliance on and off — for example a boiler, heat pump or pool pump — at the moments it's advantageous to run it. You manage them on the Instellingen relais ("Relay settings") page, under Relais.
Configuring a relay
For each relay you can set:
| Setting | What it does |
|---|---|
| Status: OFF / ON / AUTO | OFF = always off. ON = always on (manual). AUTO = the system decides for itself, based on surplus and/or battery level. |
| Tonen op dashboard ("Show on dashboard") | Show this relay as a widget on your dashboard. |
| Label | The name you give the relay yourself (the field's placeholder reads "Voer een label in" — "Enter a label") — e.g. "Boiler" or "Heat pump". There's no fixed list of appliances: you type in whatever is connected. |
| Vermogen ("Power", W) | The appliance's power rating. Used to estimate your savings when the relay isn't separately metered. |
| Minimaal batterijniveau (goedkope uren) ("Minimum battery level, cheap hours") | See below. |
Set Status to AUTO so the system decides for itself when the appliance may run — on surplus or during cheap hours.
Minimum battery level (cheap hours)
Full · the setting itself is also in Light, but switching relays on cheap hours only works with Full · see Packages
This setting determines the battery level from which the relay may switch on during cheap hours. The portal's help text, verbatim:
Relais schakelt pas in tijdens goedkope uren wanneer de batterij dit niveau bereikt heeft. Heeft geen effect bij PV-overschot.
("The relay only switches on during cheap hours once the battery has reached this level. Has no effect during PV surplus.")
In other words: this protects your battery reserve from charging an appliance with expensive grid power during cheap hours. As soon as there's PV surplus, this threshold doesn't apply — the relay can then always run on the surplus.
There are three presets:
| Preset | Level |
|---|---|
| Geen beperking ("No restriction") | 0% |
| Batterij half vol (50%) ("Battery half full") | 50% |
| Batterij bijna vol (85%) ("Battery almost full") | 85% |
Too high a threshold means the relay rarely or never switches on during cheap hours. Too low a threshold may draw down the battery you wanted to keep for the evening.
