You will need either the breakout board or the moisture sensor. Either one of these can monitor an open/closed pair of contacts. One reason you can't do it with a direct connection to the twine is that the twine won't enable a rule to be created un…

The community discussions are mainly between twine users, although once in a while the support guys speak up. I kind of hope they're spending more time working on problems than reading the discussions. If you want to report a problem, it's best t…

Temperature measurement - a simple need made complex and difficult by two different standards. For what it's worth, even though Celsius may be a more commonly used scale, Fahrenheit is a more precise mode in twine's rules because 1 degree F is smal…

You have it figured out pretty well. Mounting the twine can be done using the hole in its case, and someone figured out how to thread a coated wire through holes in the white plastic box to make a hanger loop. Double stick tape may not work well wit…

Or you can connect two wires to the moisture sensor (use alligator clips) and use the bare opposite ends of the wires as the sensor probe. That way you can keep the real sensor in a dry spot and just run the wires into the top of the sump. Keep the …

This should work as long as you are not using an external sensor for anything else, and your wi-fi router is backed up with a UPS or other independent power supply: Assume your twine has fresh batteries and is running on USB power which comes from …

Perhaps just pass along the password to the new owner so they can edit the account.

When I ordered the twine and its sensors, I told myself that this is not something I need, but it will be fun to play with. So far I'm not disappointed. My hope is that twine will perform some task that more expensive devices already on the market c…

A resistance bridge is a great way to expand the usefulness of the breakout board. The developers say they are working on a firmware update that will support analog measurements, which should make your scheme possible. Any day now?
-
I think Pete has it right. Gerry, you want the communications from your device that are directed to you to reach you. But you aren't considering that the channel through which that communication travels isn't under your control. You can also see th…

I let my twine run until it stopped reporting. The last report i received said the voltage was 2.39v. That was on day 15 after adding new batteries, with twine only monitoring temperature.
-
I'm sure there were design tradeoffs in the choice of sensor cable based on signal integrity, power consumption and component costs. There's probably other factors as well, such as reliability. For the average home experimenter, I think it's a lot e…

Your Christmas wish might be answered with this: http://energycontrol.com/Veris_Hawkeye_H908.aspx also available here: http://www.ebay.com/itm/VERIS-HAWKEYE-H908-CURRENT-SWITCH-/190762226587?pt=LH_DefaultDomain_2&hash=item2c6a50939b This and an…

Well, the twine apparently stopped working sometime before today, as there was no update in the past 24 hours, and the 2.39v reading I saw was just from the last good report received. When I removed the old batteries and measured them they were eac…

Thanks for reminding us that the temperature differences in the sensor can be compensated for with the rules (so long as the difference stays constant). I had been thinking that it would be nice to have a user supplied offset in the hardware/firmwar…

I always thought that being an alpha-tester was obvious from the very nature of the Kickstarter project. Not every idea on kickstarter turned out to be a success, and by putting our money up early we gave people a chance to try. If I wanted a tried …
-
Gerry, I concur with your suggestions, especially the use of Bluetooth for sensors. But of course my post was simply to make users who need an extra or replacement cable aware of an inexpensive source. It may not help everyone, but someone.
-
Here's an idea for attaching twine to a doorbell. First, get a small LED or light bulb that will work on your doorbell's voltage, and connect it in parallel to the bell/chime so that it lights up whenever the button is pressed. Assuming you have e…

I'm on day 17 of a fresh set of batteries, with the twine only monitoring temperature. The voltage is now at 2.39v and I haven't seen a report for 6 hours. It seems that once the voltage drops under 2.5v the reporting frequency drops also. I'll wa…
-
Several users have mentioned that wi-fi range can be improved by connecting either a usb cable or a sensor cable to the twine. It apparently acts like an antenna for the wi-fi radio.
-
Here are two excellent free Android apps for checking your AP signal strength and your network speed: *Wifi Analyzer* shows your AP signal strength as well as other AP's in range. I have not found an equivalent app for iPhone/iPad. *Network Tester…

I believe the answer lies in efficiency. A browser requires a lot of code to be loaded, and large pages to be downloaded after a URL is typed in. Depending on Internet connections the time it takes can be quite variable, and the amount of page data…
-
I see a similar pattern. My twine is just monitoring temperature and sends a report to the web page every 45 seconds, and I'm just finishing the second set of batteries in 4 weeks. I've never seen it drop into a longer sleep, so I'm not sure what …
-
I was thinking that too, but don't know if the driver on the board would need to be changed. Certainly the firmware would have to be upgraded.
-
Why not use the USB cable to connect a pair of D-cells? They'll last longer and Radio Shack has battery cases/holders for them, as well as C & AA. Even though the normal USB voltage is about 5, I'll bet feeding 3v to it will work fine with th…
-
I guess you're right, unless you want a notification every time the door closes.
-
Yes, that pushbutton or any other normally-open momentary contact switch will work. If you have the moisture sensor you can probably connect the switch to the tabs on that and it will work the same as if you had a breakout board. If you don't hav…

Go to the dashboard page and select Account to name your twine.
-
That's a very clever application, especially since it benefits multiple people. Don't forget to notify everyone when the door closes again.

I wonder if support has suspended the automatic updates in lieu of the one they are working on now. Just a guess.
