I have a linear actuator that opens a bathroom window over a shower. It's currently controlled by a wall-mounted push button with a DPDT switch to change directions. I need a relay that can function like the DPDT switch. I will also need a separate relay to activate the power supply. Maybe that might be included in a multi-relay device. The actuator has internal limit switches so I can get away with sensors that determine whether the window is fully open or fully closed. I welcome all and any advice.
I did a brief search of existing posts and didn't see what I needed although I saw something about the ZEN16 which may be usable.
I have an actuator that I use to move my solar panel. I purchased a Qubino shutter module and it works great! I connected the actuator motor’s power intake directly to it. It will reverse the polarity. It will also somehow know the fully open and fully closed position so that I may control the exact position of the actuator.
I have a ZEN17 and plan to install it using the wiring instructions for DC motors (UP/DOWN, OPEN/CLOSE) supplied with the device. I've been trying to get verification from Zooz support of the functionality. So far I haven't been made to feel confident. I have assumed that the momentary contact SPDT external switch shown in the diagram will make the actuator go in one direction in one position and make the actuator go in the opposite direction in the other position. I have also assumed that once the contact is broken the actuator will stay wherever it is. I am also hoping that these actions (extension and withdrawal) can be triggered by Zwave commands.
Here's the wiring diagram Zooz support sent me. It's the same as one that came with the device.
Toggling the switch will cause the actuator to change directions, it will not cause it stop. Actuator travel is controlled by internal switches in the device.
The only way to stop it before it's built in limits are reached is by removing the power going to the relay.
You would need a dpdt momentary switch and run the power to common and then nc and no together to the positive in the existing schematic, then other switch pole is wired as shown.
Got it. Opening fully and closing fully aren't really a problem so I'll probably leave the wiring as-is. The only remaining question: Once the window is opened I'd like to close it after ten minutes or so with a Zwave command from my hub. I plan to put an open/close sensor on the window so the hub should be able to tell how long the window has been open. At that point I want the hub to send a signal to the relay to close. I hope this is possible. Is there any trick to doing this?
That should be pretty easy to setup. You can use Basic Rule or Rule machine to create a rule that will trigger with the sensor opening, then wait for 10 minutes and send the signal to close.
I grabbed a couple Zooz Zen17 relays and some smaller 2" Linear Actuators and rigged them up with a virtual switch and webcore magic. Works perfect!
It raises the lid of the feeder when On is triggered and Lowers it when Off is triggered on the virtual switch.. The lid just sits on the actuator and is not attached to it so if the actuator closes and a critter is still there the lid wont force shut on them. The automation also turns off the relay after a few seconds.. I used a 12v power supply hooked to the zen17's power supply ports and NO(+), NC(-) relay ports. Then R1(C) (+), R2(C) (-) to the actuator.
Set the Zen17 to DC motor mode in hubitat with it turning one relay off when the other is on.
I do something similar with a water valve opened by an actuator, though in my case the valve is AC powered and opens when power is applied. Since it only needs to be open for a few minutes every couple of days I just use a smart plug. I use it to irrigate my plants.
I use this Zigbee controller to fully extend/fully retract the actuator. No brainer. Actuator motor lines to the COM and reverse the 12V power lines on each relay.
How did you get the dual relay to work in Dashboard with the linear actuator? When I set one up I was able to go to the device and select on/off and it worked to control the actuator in/out. However when I set up the button in the dashboard as a switch it just clicks. I've tried the dual relay and Zen17...anyone have step by step instructions. Trying to set one up for first time for a high school that I am helping with as a volunteer.
For the dual relay, select Generic Zigbee Multi-Endpoint Switch as Type. That should create two "children". To operate the "switch" you use the parent device. Hopefully, this solves your problem.
