Understand how Controller uses device priority, device type and control mode to decide which controllable asset is planned first.
When several controllable devices ask for the same limited power, the scheduler needs a consistent order. A device's priority is the first decision layer. If two devices have the same priority, Controller compares their device type and then their control mode.
Read the flow from left to right. The scheduler only moves to the next filter when devices are still tied after the previous one.
Your explicit preference is considered before any automatic device rule.
Devices with the same priority are ordered by how flexibly SmartgridOne can control them.
Devices of the same priority and type are ordered by the active operating strategy.
The first differing filter decides. Only devices that remain tied continue to the next filter. Priority therefore changes planning order, but it does not bypass grid limits or device safety limits.
The default level is Normal. Change it only when the installation needs an intentional preference between controllable devices.
Start with small differences. Set the most important device to High and leave the others at Normal. Use Highest and Lowest only when the operational preference must be unmistakable.
Controller builds the plan in two stages. The first stage handles devices that are available for active planning. The second stage adds solar without an active external curtailment setpoint and EV chargers without a connected vehicle.
Within each stage, the numbered order is applied before the scheduler moves to the next group.
Plan controllable devices that can influence the current energy balance.
Complete the plan with devices that are not actively available in the first stage.
Within the first stage, Controller applies the following hierarchy:
If a solar device has an external signal configured but that signal is not active, local control applies and the device moves to the second stage.
The second stage is ordered differently:
Imagine a workplace with three charging points and limited power at the grid connection. The vehicle used by field staff should be ready first. Give its charger a higher priority and leave the other chargers at their normal or lower setting.
The available grid power remains the same. Priority changes the sequence in which the chargers are evaluated when they compete for that power.
Evaluated first because this vehicle is needed for daily operations.
Evaluated after the higher-priority charger.
Evaluated last while the power budget is constrained.
Priority defines the queue, not a guaranteed power allocation. The actual result still depends on connected vehicles, their charging limits, the active control mode, other site loads and the configured grid limits.
Heat pumps, boilers and on/off loads do not always report their own consumption. If the load is not measured by the device or by a dedicated energy meter, the EMS sees that consumption as part of the building's base load and cannot reliably use it in device-priority planning.
Add a dedicated measurement when the scheduler must distinguish a fixed load from the rest of the building. Without that measurement, changing its device priority cannot create information that the controller does not have.
