What if there is a connection with L2 & L3 @ the same time?

Thinking about adding a zwave switch to L2 & L3 to set it to High or medium. I can with Lua switch L2 or L3 off when enable the other one but there is possible some time there is power on both. So what happens then?
Likely it will go to High at that point.

This is my mysensors version on ventilation control

https://github.com/Tristan79/Vento

It also has the schematics for the various brands out there :-)

:-)

5-50 euro of parts depending: if you like me, build it as an extention cord/box in between the unit cable and the power-socket such that it is non invasive... (since its not mine) or...

anyway was planning to improve the thing a bit by getting the power of the unit from the periflex cable itself and adding a electricity use (watt, watt/hour) sensor to it...

i also have a esp8266 version of it. nothing fancy, it implements the switches with a very tiny http rest api :D instead of using the mysensors library. probably going to use that in the next version... i can dig it up from my broken notebook if someone is interested and post it on github.

Could use hints and advice on powering the box from the cable itself and with measuring watts. :?: Which sensor would be appropiate and accurate enough to use...

Also i will check that variable motor dimmer thingy thread
that looks interested

:D

A while ago I bought a Sonoff module and flashed it with ESpEasy firmware.
Hi Kees,

I flashed a Sonoff with Tasmota and connected it to my Storkair ventilation. I would like to leave the ventilation running on 1, and have it switch to 3 when I activate the Sonoff. Currently it just switches completely on and off when activating the Sonoff. Any tips?

Looks like not L3 but L1 is the high mode of your unit, but i can't really see it in your image.

Would it help if I made some additional pictures?

One picture with aclear view of the schematic on that junction box will do.

Thanks I was not following the topic for a while but will make a picture asap.

What you need to do is make sure the L3 terminal of Ducobox gets connected to the mains voltage line (L) when the relay switches on.
If the Ducobox detects 230V on L3, the fan will be set the High. (You could also connect it to L2, it will go to half power).
What if there is a connection with L2 & L3 @ the same time?

Thinking about adding a zwave switch to L2 & L3 to set it to High or medium. I can with Lua switch L2 or L3 off when enable the other one but there is possible some time there is power on both. So what happens then?
It is safe to connect more than more than one "L" to mains at the same time. The box will switch the fan to the highest powered level. I checked this with the manufacturer and he said it was no problem.
So now I have my box always connected to L1 and use a fibaro double relay to switch L2 and L3, giving me all speeds except off (but a minimum level of ventilation is more then welcome). Also by switching error I proved that nothing breaks when you switch on L1, L2 and L3 ;)

So that took you a while.

You need to have L3 connected to L (brown) at all times.
Additionally switch L1 with L (brown) via the Sonoff.
