Domoticz

Situation:
Everspring humidity sensor st814
Fibaro 2x1,5 kw relais
Domoticz with Aon stick

I want to control my bathroom vent (itho eco-fan cve hp) with de humidity sensor.

The sensor and the relais are visible within Domoticz.
I've made two switches "ventilation low" and "ventilation high"

When i use the first switch (low) the fan starts but in middle speed. When i then use the switch (high) the fan speeds up to high speed. When i set switch (high) to "off" the fan goes tu low speed. Strange.

When the fan is in low speed and the sensor is set the fan speeds up to high speed.

Now my second problem.
When the fan is off and the sensor is set the fan doesn't starts.
(Switch high in ddomotics goes to on)

Any ideas?

im kinda lost, mostly around the fan, it apparently has 3 speeds, so how does it show up in dom? i cant think of a good way to handle a 3 speed switch. I dont have one to play with either, my fan is on/off only, but i was considering setting up what you're talking about... just i think the thing is the speed probably doesnt matter since if you turn it on at the right time, the speed will likely be unimportant, you usually want high to quickly clear it, but if you can keep up with it at whatever speed, thats all you need.
Just like you said, based on the sensor value you'll set the fan speed, well since its automatic, you'll probably never get to the point where it will ever trigger the high. I think really what you need to do is find the right speed (what clears a hot shower the best) and just stick with that and do an on/off for it.

otherwise I think you'll need to do some LUI stuff and for that we'd have to get a better idea of what commands/states we'd be working with.

Can you share information on the switching of your ventilation?
I used to have a 'balance' ventilation system which worked like described below, does the same apply to yours?
3 live wires connected, I did not have automation only a manual such.
Wire 1 not switched (always on at low speed)
Wire 2 switched (when on go to medium speed)
Wire 3 switched (when on go to high speed)

Van you share your blockly (?) controlling it?

I'm at work right now, wil share tonight.
