Hi,
I’m looking for a simple ventilation setup, with a silent 12V regular PC fan, typically 12cm or more. Just to keep it simple, I’m thinking about controlling the fan speed with a 12V Zigbee Led dimmer. Have anyone done something similar? Would it be possible to control fan direction in any way?
Thanks for any help or ideas.
Have not tried but from researching the control of AC fans I know that fans can not usually be speed controlled by using a dimmer, instead you would normally need a “fan-speed regulator” or “linear regulator controller”.
I do not know if a Zigbee based fan-speed regulator product compatible with 2 volt DC fans.
Hi Jreidel, did you find a solution to drive the 12V PC fan using a Led Dimmer (one only color I suppose)?
I found this product, but I don’t know if working
If you have any idea (or solution), thanks in advance to keep me informed, I’m looking to the same simple ventilation setup, too!!
Regards
Giorgio
Slightly different solution- but someone has an ESP-based method for this.
Perhaps a 5v fan would remove the need for a step down transformer and simplify things further.
Hello everyone,
I came across this thread while searching for an easy solution to control a 12V fan. I wanted to share my final solution, which involves using a “Shelly Plus RGBW PM.” This device supports high PWM frequency and works quite well with a 3-pin fan. I tested it with an EBM-PAPST 4412FGPR, and the results have been excellent.
I’ve set up some helpers in Home Assistant and used Node-RED nodes to manage everything. So far, everything is working absolutely great!
How has it been working ? Any updates? Have been thinking about doing the same with 4 noctua 140mm fans, but don’t want to risk setting anything on fire…
