  • Robert, From the photos in your article it looks like the machine screw used to attach twine has a nut behind the metal panel on the garage door. So it might be difficult to remove when you need to change batteries. A better way would be to insert…
    in How are you attaching Twine to things? Comment by Bill Spencer November 2012
  • Sean, reading your last msg it makes me think about Twine's original description on Kickstarter: No programming needed! I'm just kidding, but it's clear that some users need a simpler approach to accessing Twine's data. (:

  • Depending on how your sump pump is plumbed and where the sump is, you might be able to use the moisture sensor to detect when the sump is full or empty. As I noted elsewhere, you can extend the sensor with wires to home-made water contacts that you…
    in Power on switch? Comment by Bill Spencer November 2012
  • Maybe the developers will answer this: Will a direct short across the sensor terminals, either by a switch or a photo cell, cause the sensor circuits to draw more current from the batteries? This might be the only reason to avoid this technique.

  • I wonder if Staples or other source would have a plastic business card holder that would fit Twine. I tried one but it was not deep enough (front to back) for Twine, but there are different sizes. Then, the plastic holder could be fastened to what…
    in Non-penetrating way to attach Twine Comment by Bill Spencer November 2012
  • And further to this point, if there is a way to tell when Twine is on USB power, would it be possible to switch to more frequent reporting intervals, since saving battery power is no longer a requirement?

  • I believe you can build your own sensor contacts and connect them with wires to the twine moisture sensor. Use alligator clips to attach, for testing at least. Any conductive metal that won't corrode in whatever you're measuring should work. This…
    in Waterproof moisture sensor Comment by Bill Spencer November 2012
  • I tested the moisture sensor by shorting the two legs with a wire jumper, and it showed "wet" when shorted. It appears to work as an open/closed switch sensor. Also, you can extend the sensor contacts with wires and it still registers properly. So…
