I measured a number of devices with an ELV Energy Master, which is known to be quite accurate.

These are the results:

    Device                 off      on      both on
TP-Link HS110 V2           1,2 W   1,8 W   x
TP-Link HS110 V3           1,0  W   1,8 W   x
AVM FritzDect 200          0,5  W   1,3 W   x
Gosund SP111               0,3 W   0,6 W   x 
Blitzwolf SHP7             0,3 W   0,7 W   1,1 W 
Shelly 2.5                 0,9 W   1,2 W   1,5 W
Technisat Rollershutter    0,4 W

The measurements were done after the devices were configured and fully booted.

When unconfigured, the TP-Link devices used more power. The AVM device was not tested unconfigured.

As you can see, power consumption also depends on the hardware version of a device.

Gosund SP111 is internally indentical to Blitzwolf BW-SHP6

The Shelly 2.5 device really disapoints me. It basically has an ESP8266 inside, like the Gosund and Blitzwolf Smartplugs. So energy consumption could be 0,3 W when both relays are off. With 0,9 W of standby consumption I must somehow connect a mechanical switch, because with 10 roller blinds are 9 W or almost 80 kWh per year wasted just to control them via smarthome.
