1SINQ OneKey

← Heating

OneKey heating controller with evcc integration enabled. The heat pump is controlled via SG Ready states (1=dim, 2=normal, 3=boost). The device's energy manager must run in SG Ready mode with evcc selected as the SG Ready source. When evcc runs on the OneKey device itself the broker is localhost.

Supported features

Built-in meter: Support for an integrated meter.
Dimmable: Power consumption can be reduced (e.g. § 14a EnWG). See External Limit.
