Fibaro single switch: to control the fan
Fibaro Dimmer 2 to control the lights.
I don’t believe you need to put both Fibaro modules behind the light switch. I think you would install the Dimmer 2 behind the light switch (no neutral required) the single switch would connect to the directly to the fan. Mine is in the attic, if your’s isn’t perhaps it can be located behind the isolation switch?
From what I’ve seen on here in previous threads, you disconnect the signal wire from the switch that goes to the fan and switch it on using the Fibaro switch instead. Turn the timer down as low as you can so it turns off when the Fibaro switch turns off.
If you are using a Fibaro Dimmer to control the lights, why would you require smart bulbs? Perhaps if you want colours. I just want mine to be dim and for the fan not to come on in the middle of the night.
Slowly! My refurb isn’t happening until Feb '18, so plans not finalised, but they have progressed a bit.
I’ve decided to go with smart bulbs vs the fibaro & ecoled approach: I like the ability to customise the colour and brightness of each bulb individually and I’m a little nervous of the dimming issues I’ve read about with LEDs controlled by smarthome dimmers - I’d rather my bathroom refurb didn’t get delayed or affected by those issues, it’s going to be disruptive enough (it’s my only bathroom)! With smart bulbs any issues I can resolve later, vs needing an electrician if there are issues that need more complex remediation.
I’ve ‘solved’ the bulb depth/placement issues in two ways: relying on osram smart+ GU10s instead which have normal GU10 depth and locating them more centrally in a quad unit (or 2 x double fittings) - avoiding the need for IP65 fittings and placement on the sloped ceiling. Although the ansell mini icages would have met my needs to for matching fixed/adjustable fittings (although not for the Hues because of depth).
I haven’t decided on the extractor fan, although I’m still biased towards hooking it up to smartthings with the aeotec. As @jymbob suggests it does perhaps add some unnecessary complexity, when there are fans with humidity sensors built in.
But personally I like the separation - a dumb fan doing what it’s good at, with the sensing and ‘intelligence’ left to the smarthome components. Reading reviews of extractor fans with built in humidity sensors I’m left with the impression they can be problematic and unreliable - even the more expensive ones don’t seem much better - and if the sensor fails or stops working properly you’re likely to have to replace the whole fan unit. That generally confirms my experience with this kind of stuff: when dumb objects are augmented with components that lie outside the core competence of the the manufacturing company, it’s better to go with separates from specialists. Although, of course, smartthings has it’s own set of issues which will no doubt introduce some reliability problems etc. but I guess I’m more comfortable with those 'cause they’re familiar!
I also like that I can have much more control within the smart platform, for instance having different rules for operation during the night to reduce noise.
Something I didn’t mention earlier, they’ll also be underfloor heating which I plan to use with the heatit thermostat to connect it to smartthings.
We had a shower room built a couple of years back, with a humidity fan. Electrician said he always had issues with them.Guess what it is shit.
never stays on, so we have to manually leave it on
either that or he is a shite electrician ( possiblity there ) need to check wiring one day
but i am thinking timer fan with fancy sensor .
but cost will always be considered
Indeed; the Airflow iCON are otherwise great fans (quiet and efficient), but after going through 2 humidity modules (that just failed, stuck ‘on’) and one timer module in ours, I finally ripped it out and replaced with a much simpler pull-cord only fan. I’ve yet to make it smart in any way, so am following this with interest…
Just for an alternative data point, my Xpelair Contour C4 has now been installed for 6 months with no issues with the timer or humidistat. I set it when it was installed, haven’t had to touch it since.
