Loosely based on the Dust Collector Controller https://hackaday.io/project/167479-just-another-dust-collector-controller and will replace the existing relay controller https://hackaday.io/project/167633-just-another-whole-home-control-system/log/168845-automated-curtain-rod-module

This project will control up to 3 zones of METTechs' CL200T and CL338H motors. The controller can provide up to 3 special function inputs to detect when a zone is open, closed or requesting to be open. All control lines are sent over a standard CAT5/6 cables terminated in a RJ45 at the controller side. On the motor side; the cable can be terminated into a RJ11 or into a breakout board. Each zone has jumpers to control what special functions will be sent to each zone.

windowscontrol.yaml

This ESPHome control file uses the sun to automate the opening and closing of drapery in 2 zones in my house via Home-Assistant. The control file also includes 2 interlocks that help prevent the drapery from being opened from automation at night or with I want to make sure I have privacy.

The PCBs have come in and assembled. I created 2 boards, one that will be the central controller and a second optional breakout board. The breakout board is only needed if you won't don't want to "directly" wire the controller to the motor housing.

The controller board can route 4 functions to each zone. There are 2 global inputs and 2 "zone" inputs. A total of 3 switches and one common could be routed to any zone over a CAT5 cable. If a separate common line (12v) is routed separately, such as with my LEDs, you could return 4 switches.

I was a bit tight on a few of the interconnects and the relay header butt a bit too close to the NodeMCU and has to be slightly bent.

But overall the board turnout great!
