So in my quest to have ancient appliances tied into the HA juggernaut I realized that getting up to pull the cord chain on my 40 year old Hunter ceiling fans is just.... the pits.https://ift.tt/tlDQZkA have that. So I figured it was time to do a little upgrading. The fan is quite simple 80's technology: it's on a switch, in the center of the room, and the only controls are a pair of pull chains for light & fan, and a slide switch for fan direction.I've already put a smart bulb in it, so that's working. Ultimately I'd like to control the fan in such a way that all the "stock" controls work, but I can control fan speed, direction, and in a perfect world the light bulb so I can use a normal "dumb" bulb if I want to.First step was to take the fan apart. Being 80's tech it's.... a lot of wires. https://ift.tt/Sg3Iobr what I can see, the fan goes forward and backward via a DPDT slide switch configured in the usual reversal wiring mode. This would mean I'd need a DPDT relay to replace the switch, and if I want to keep the old switch I may need a second DPDT to route the switch logic to either the normal switch or my reversing relay. The motor itself is run off a 3 way pull switch. This has 4 wires which includes one source, then two wires that go through capacitors and a third wire that probably runs the motor. This is how it "slows down". And this could be complicated to automate: I either need a true motor controller or three SPST relays to turn on the capacitors plus another SPDT relay to switch the motor power to either the relay network or the pull switch. That way one can either use the automation or the pull switch.As I'd like to do something before I go nuts I got a small Shelly Mini1PMG switch, wired the hot and neutral to the power that runs the light (as it's always "on" now) and wired the switch to source into the black wire on the 3 position pull switch. So now I can sit in my bed, throw the switch, and the fan will come on to the speed of the pull chain.Not perfect, the pull chain can only now set the fan speed, not run the fan without the automation but I'll automate it into the Ikea wireless switch I have that controls the bulb. One tap will turn on or off the bulb, 2 taps will do the fan.https://ift.tt/r7o2z0l thoughts on a very small set of relays or maybe a very small integrated controller? I can use Zigbee, ZWave, wireless, whatever. It just has to be very small because there is not a whole lot of room in there.....
