I stumbled across this thread while searching for something related and thought I'd resurrect it to mention my HASwitchPlate project, which utilizes an ESP8266 as a MQTT-to-Nextion gateway to act as a wall-mounted scene controller. The project includes code for the ESP8266, Nextion, and home automation platforms including Home Assistant and OpenHAB. A PCB has been developed to allow running from AC power, and 3D-printable models are provided to mount the project into a single-gang work box common in North America.
The end result is a scene controller you can build yourself with all the necessary components (software, electronics, and physical enclosure) ready to download.
@Nca78 said in Anyone using a low-voltage motor controller?:
@NeverDie how low is the voltage ?
L9110 can go down to 2.5V and is ultra cheap on ali, else there are also plenty of DRV8833 (min 2.7V) breakout boards it seems ?
Thanks! They're so cheap that I ordered both of them just to have them on hand for the future:
Meanwhile, for expediency, I ordered two different kinds from Pololu:
Very nice project you have here! Thank you for taking the time to post/share your work!
At first I thought it might be exactly what I was looking for, but reading through everything now I am not so sure.
I have been studying various ways (Wi-Fi, 433/315 Mhz RF, MySensors) to implement controlling RGB lights and I initially thought Wi-Fi (while readily available, easy, and cheap) might be too "slow" in response time, which got me thinking to use MySensors (with NRF24) instead, which led me to this thread (among others).
Something concerned me though, I see in your GitHub for this project you stated:
Project frozen/final - This project is done from my side. It has been working for years but I switched to another solution so I won't update this anymore.
and on your OpenHardware page:
Update2: They have been running for about 2 years now mostly without problems. The only disadvantage is that my Mysensors network overall is quite "slow" (~1s reaction time). I am currently experimenting with Wifi RGBWW controllers (H801) so there wont be to many more updates to this project
Which made me want to ask you what you are using now?
It seems to me that those MagicHome type Wi-Fi (or RF) RGB controllers would be pretty hard to beat price wise, I don't think I could implement similar functionality (including packaging, etc.) for the same amount of money, and that's before even counting my time.
Also I am still struggling with reliability of my MySensors network in general, but I hope to be able to still solve this as it seems that many others have been able to (but that is a different subject altogether).
