I have a dimmer switch and a regular switch on a 3 way circuit controlling my ceiling recessed lighting. I’m wondering if I can eliminate the 3 way circuit and get rid of my dimmer switch. Is this way more involved than just popping the dimmer switch out and reconnecting the wires leading to it? There are 2 separate groups of wire leading to the dimmer switch one with a red, black and white and the other with just black and white. I wish I could explain it better but I know nothing about wiring. In the picture there are 2 red wires and a black wire coming from the dimmer switch. One of the red wires is connected to the red wire from the group of 3 and the other red is connected to the black of the group of 3. The black wire from the switch is connected to the black wire of the group of 2 wires. The white wires from the group of 3 and 2 are connected.
One of the red wires is connected to the red wire from the group of 3 and the other red is connected to the black of the group of 3.
There are always two traveler wires carrying switch hot back and forth.
So the red and black wires that come from the same cable are the travelers.
With a three way switch/circuit..... the device always has a common terminal. A switch would have a dark colored screw for common and two brass screws for the travelers. A dimmer that uses individual wires would label the common wire. In this case the two red wires are the travelers and the black is common.
Connect the black common dimmer to either traveler wire. Cap the other one off.
So if you connect the black wire from the dimmer to the black wire of the travelers.... that will leave the red wire to be capped off.
I would like to replace some ceiling lights with light+fan combos - the type with the strings to turn on fan and light.
Do the fan combo lights require anything beyond a normal light fixture in terms of wiring or other considerations, or will I be able to simple swap using the same wiring?
I have a 4-Position 3-Speed fan selector rotary switch similar to the pictures below. It's mounted on a wall plate so that I can select the speed of my HVAC fan. I was wondering if there are any wall-mounted wireless devices on the market that I can replace this with so that I can control the fan speed remotely? The typical smart thermostat doesn't cut it since they are not meant for line voltage and are only single-speed.

Background: My overall goal is to redo how my HVAC system was set up in my condo. It's a water-cooled AC system where the cooling is controlled by my thermostat (opens and shuts a valve controlling the cooled water) but the fan motor is a separate manual rotary knob located in another part of the home. It's always been a pain to remember to turn on or off the fan when the AC is on or off and also when I want to change the fan's speed. I'd like to try to automate the system so that I can turn the AC and fan on/off wirelessly and simultaneously.
