# Stiebel Eltron WPM 3/3i (SG Ready)

Source: https://docs.evcc.io/fr/heating/stiebel-eltron-wpm-3-3i-sg-ready

SG Ready control via Modbus with the ISG only works in domestic hot water (DHW) mode and in automatic/programmed mode. In comfort mode, SG Ready commands are ignored. The WPM 3/3i does not provide power consumption via Modbus. Without an additional meter, power is estimated from the charge current.
