I may have a firm reason to try some Inovelli stuff once this all launches. Good fan control is severely lacking in the market right now. I have always been watching their products but get deterred by the price.
Anyway... for switches/dimmers. it really depends on what features you want.
- Do you have a lot of 3-way switches?
- Do you want to be able to do 3-way synced dimming?
- Do you want a programable LED bar to use for notifications?
- Looking for Budget, or best features?
- Looking to buy at a local store or online?
I do recommend using mostly dimmers where possible, the cost is usually about the same and even if you only use 100% brightness the option is still there if you do want to dim the lights.
Zooz is what I use, they are low cost and can be used in a 3-way with any standard dumb 3-way switch. They also have a good feature set with many settings so it can be used in almost any situation. Supports up to 5x button taps. If you do want to check out Zooz, you can find links to all the products on my custom driver post, if you buy through those affiliate referral links in my post it supports my driver work: [DRIVER] Zooz ZEN Switches Advanced (and Dimmers)
Inovelli are a little more innovative and have more front facing features, but cost is a little more, and they sometimes run out of stock due to high demand. I think they have at least all similar features and functions of Zooz plus probably more (I do not actually own any). They do have the fancy programmable LED bar which is an upgrade from the basic LED that Zooz uses.
The other most popular would be the GE/Enbrighten/Jasco devices. A lot of people buy these at local hardware stores. They have minimal settings and flashy features but seem to work good for people. They at least do have Double Tap button support so you can use them for some "scene" programming.
