Hi everyone, I am a newbie at the Vera/Z-wave/electric world but I wanna try to create some fancy solutions in my home.
For info I own a Vera 3.
My goal is to make the ventilation unit go to max strength when I shower, to draw the moist air as quick as possible out of the bathroom.
To achieve this I was thinking about mounting a humidity sensor in the bathroom combined with a z-wave circuitbreaker of some sort that will be mounted inside of the ventilation unit. I know my ventilation unit has this option, if I connect two wires to pin 11 and 12 inside into the electricpanel and short them, the ventilation unit will go to max.
I was then thinking about setting up in Vera 3 this sort of trigger: if humidity is above x, then short cables inside the ventilation unit. Remain short untill humidity is below x.
Is that easily setup and is it a good solution? If yes, what components would you recommend for me to buy? I live in Norway and we use the Euro standard.
The ventilation unit I have is a Villavent VR-700-DCV ventilation rotary unit [url=http://www.systemair.com/VR-700-DCV_envv-12425.aspx]Systemair Global | Systemair
Just to clarify - The ventilation unit is in a separate room without the possibility to wire all the way to the bathroom. Thats why wireless would be great.
BTW: If the forum admin reads this I want to give some feedback about the verification picture to letter thingy for each post - it’s a bit difficult to read the letters in the picture and I had to try 4 times this time. Hope you can look if there is something that can be done. Thanks.
I tried something similar but found the performance of Z-Wave Humidity sensors disappointing. I had problems with both accuracy and reliability on two different models of sensor. It sounds like a simple thing to do but, in my experience, it is far from easy to get good results. I now run my extraction according to how long the bathroom light is turned on.
In a previous home I had an electrically-pumped shower so I just took a trigger from the pump motor. Shower on → Fan on. Occam’s razor triumphs again.

Thanks, this is a really good tip. What z-wave device would you recommend me to use in the ventilation unit to short to wires? Low voltage

I am not sure if you have completed this, but I have done what you are trying to do.
A temperature sensor and a relay.
I mounted the temp/humidity sensor just above the top of the shower. The relay was mounted in a box next to the ventilator unit. This relay has a zero potential relay so it does not put any electrical power to the ventilator unit, it only connects the wires. The relay must however be supplied with power to operate.
When I finished the installation I set up 2 conditions in PLEG to control the ventilation override.
It works perfectly and it is used every time someone takes a shower.
Note that when you have the relay connected you can make all sorts of automation. You can schedule when you want high ventilation etc…
Let me know if you need the PLEG logic.
Too bad there does not seem to be a water flow sensor available. Then you could use it to start the ventilation up plus a timer so it will run a bit after it ends. We also need a good humidity sensor for z-wave as well.
