This is my first post in the forum and I need help with hardware selection.
I am looking for a low cost momentary contact Z-wave or Zigbee Switch. Essentially, I would like to swap a normally open push button with a smart switch.
Currently I am considering getting a Mimolite which retails for ~$60, but wanted to ask the community if there is a lower cost solution that works well. The Mimolite has the input port which I do not need and hence would like to not pay for it.
The switch will be used to turn on the re-circulating pump of my home’s hot water system. Currently I have a push button I bought from radio shack, but I would like to swap it with something I control via SmartThings.
UPDATE: The push button goes into the system controller box, hence the load is minimal. Voltage: 5V, Current: Not specified, but assume a few mA.
To be clear, you want something that connects to a dry contact-type input on your pump, rather than something that’s actually providing power to your pump, correct?
If holding the button down for an unknown number of seconds doesn’t cause a problem, for a few dollars less you could use something like this, and program it (probably using WebCore) to turn off “immediately” after ST turns it on, but the amount of time for the commands to make it would be variable.
Another option is a button pusher like a Switchbot but then you need their hub to integrate with ST and you’re back in the same price range as a Mimolite.
To my eyes, the Mimolite is the best option as it’s designed to do what you’re asking and you’ll probably get a more reliable result while spending less time trying to make it work than the other options. And you might find a use for the input, like monitoring the pump to confirm it’s working as commanded or tracking runtime.
Hi Mark, you are correct, I need something that connects to a dry contact-type input on my pump.
From the research I did prior to writing this post, I thought the MIMO Lite was the best option , but the $60 price tag hurt a bit. Hence me asking the community, if they were aware of an equally capable solution that was cheaper and only had the output capability.
With some further research, I found these Chinese made contraptions, any comments on these or other alternatives:
Have you looked at the Qubino Flush 1D Relay?
it seems that not only is is a dry contact relay but it also has some configuration options for things like momentary on Or multiple inputs to also trigger an action.
I see it as a perfect answer for a garage door opener or gate opener as it could use a physical button as an input allowing me to trigger a scene with a physical button or remotely via Z-Wave.
I’m just not sure on the configuration part as the instructions describe the various configuration parameters but does not mention how one interfaces … DIP Switches? Separate App?
