# 1SINQ OneKey

Source: https://docs.evcc.io/en/heating/1sinq-onekey

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: meter, dim
