Update on the ITHO ECO-FAN:
I still had the ITHO ecofan Perlilex version.
This version can be controlled wireless with the additional 868 MHz remote control and the existing wired (3 position) wall outlet.
This week I replaced the Perilex connector with a standard connector, Adjusted the wall outlet to a normal one.
Now its possible for me the measure the powerusage with a Plugwise circle.The Itho Eco-fan is beyond expectations using:
2.2 watts in position 1 (default)
7.0 watts in position 2
40 watts in position 3
Now I can only control the Eco-fan with the remotes, one is placed in the bathroom replacing the old manual controller.
And one is connected to my home automation system and can be switched on based on humidity, Temperature or any other reading.
Switching off can be done the same way, to determine if the Eco-fan is on I can now use the plugwise circle and check the energy usage (>=4 watts is on)
I would rather like to create a potential free switch on the Itho Eco-fan to see id its on or off. But this is not that easy
, any help on this would be appreciated.
This is one off the better energy saving projects last year minimal benefit of 30 watts per hour.
