Required scope: energy:write

Limits the node to limitW watts until expiresAt (must be in the future), after which the limit is lifted automatically. A limit of 0 fully curtails the node.

A node holds at most one external power limit: setting a new one replaces the existing one. While active, the external limit replaces the node's configured and scheduled powerLimitW, so it can be higher or lower than them. The node's fuse limit still applies.

The active limit is returned as externalPowerLimitW and externalPowerLimitExpiresAt on the node in GET /sites/{siteId}. Both are null when no limit is active. A limit set by a meter integration may have a null externalPowerLimitExpiresAt.

On a node with a Perific meter that has a digital-input rule configured, the meter controls this limit and overwrites or clears it on every meter report.
