Vibration sensor: Not tripping "on" trigger?

Joel Finkle — Thu, 31 Jan 2013 16:57:36 +0000

As part of my sump pump monitoring, I have a matched pair of rules:

1) Starts shaking for 3 seconds / untrigger after 2 seconds, 125 mili-G sensitivity

2) Stops shaking for 3 seconds / untrigger after 2 seconds, 125 mili-G sensitivity

The actual shaking that I've watched happen is around 500 mG -- the pump installed today is a lot quieter and smoother-running than the old one, which ran closer to 700 mG vibrations.

Both rules set an HTTP Get to my Google Spreadsheet web app.

I have noticed that I occasionally do not get the Starts Shaking trigger before getting the Stop Shaking. That doesn't make much sense. Any suggestions for adjusting the settings?

Twine becoming unresponsive after an hour of no activity?

Manuel Grossi — Fri, 04 Jan 2013 10:22:06 +0000

Hello

My twine stops reporting after about an hour of no activity. I can only get it to work again by taking out a battery and putting it back in. Any ideas?

Plotting magswitch states on a timeline in a Google spreadsheet?

Andrei Goncharov — Fri, 11 Jan 2013 11:11:16 +0000

Following a thread regarding combining Twine and IFTTT, I've created an autoupdating spreadsheet, which saves all the magswitch state changes like this:

January 11, 2013 at 07:41PM Closed
January 11, 2013 at 07:41PM Open
January 11, 2013 at 07:52PM Closed

Now, is there a way to plot a timeline based on this data, that would graphically show for how long each state lasted? I imagine this would require reformatting the time and finding a proper visualisation type, but really no idea how to do this. Anyone tried anything similar? Thanks!

Using Twines for monitoring room temperatures

Andy Horne — Mon, 04 Feb 2013 16:32:16 +0000

I showed my Twine to a colleague and he is keen to buy 4-5 and use them to monitor the temperatures in several rooms in his house, and asked about setting up a web page to show them all. I only have one Twine so don't know what the web page looks like with multiples.

He said ideally he'd like to set up a page with his house plan as the background and overlay the Twine results to show the real-time temps in the rooms. He'd also like to have a history (I told him some people have enabled reporting to a spreadsheet).

Does anyone have any examples of multiple Twines reporting to a custom web page? What's the best approach for this?

TIA.

Is my dog barking?

Andrew Knasinski — Tue, 29 Oct 2013 13:10:32 +0000

I'd like to setup a sensor to ping me if my dog's barking, but only seem to find collars that go on the dog which I assume measure sound and vibration. Any ideas are most appreciated.

Using wget to get temperature data

Phil Tomson — Mon, 18 Feb 2013 12:48:16 +0000

In another thread I found a shell script used to obtain temperature info, here's the part I'm interested in:

#!/bin/sh

/usr/local/bin/wget -o /tmp/log.txt --quiet -O /tmp/temp.txt --keep-session-cookies --save-cookies cookies.txt --no-check-certificate --post-data="email=&password=" https://twine.supermechanical.com/login

/usr/local/bin/wget -o /tmp/log.txt --quiet -O /tmp/temp.txt --load-cookies cookies.txt --no-check-certificatehttps://twine.supermechanical.com/rt/?cached=1

In the second wget there is a - what is the twineID? How can I find out what my twine's ID is?

Twines aren't communicating

Michael Driscoll — Sat, 18 Oct 2014 18:42:48 +0000

I can't get the computer Windows 7 pro wireless to see the twines. They had been working on a different WiFi network and now I can't see them to change the network settings.

Post Variable Length

Eric Dexter — Sat, 30 Mar 2013 16:48:35 +0000

Now that you've updated the max URL length (what is the max length btw?), and allowed POST requests;

There still seems to be a rather short maximum POST variable length. I'm trying to use an android service called "notifymyandroid.com" and the minimum variable length necessary to fire off a message (including API key, event, status and description) is 91 characters. But, in 91 characters, that is an event, status and description using 1 character each.

From what I can tell, your variable limitation is 99 characters.

Here is an example minimum POST data:

apikey=A99da857s40f632d37s17ae623ddadb7c221aac7351bd4a9&application=t&description=x&event=o

Also. a bug: When you save a POST request, then return to the webpage, it reverts back to a GET request (although the post data remains hidden in the POST data field).

Magnet sensor response

Alan Page — Thu, 27 Dec 2012 05:00:02 +0000

Twine setup without incident using the magnetic sensor, but the sensor is always open (does not recognize the presence of the magnet)? How does one troubleshoot the system or should I just return the sensor?

Suggestion - set update flag on webservice return

Chris Cragg — Tue, 06 Nov 2012 08:19:44 +0000

When the device reports its data, that would be an opportune time to inform it of a needed configuration update. The webservice would simply return a boolean. This flag is set if the configuration was changed in your web IDE. That would prevent me (and others) from having to go to the device to turn it over, to force the update.

New Forum Format Needed -- Agree/Disagree?

James Kelly — Wed, 21 Nov 2012 20:52:10 +0000

As more and more folks get their Twines, this format is going to get difficult to use IMO. Maybe I'm wrong. I'd like to see the more common format with one page of major sections, then tapping that takes you to more granular section headings... followed by posts. Comments bump a discussion back to the top and admins can pin important discussions. Agree/Disagree?

Not reading Temp. correctly

James Boutin — Mon, 06 Oct 2014 11:58:15 +0000

I setup my Twine this morning and it seem to be working correctly. When I moved it to another location, approx. 100yrds away into another building on another wireless network it is not now reading temp. correctly as displayed on my dashboard. Does Twine need to be configured for that network and if so how do I accomplish it?

$35 breakout board, worth the cost?

Mario Juestel — Wed, 09 Jan 2013 16:31:16 +0000

Just curious... for those of you who have purchased the breakout board, is the $35 cost justified?

I initially purchased a Twine only, without any sensors and have been thinking about adding the breakout board. Is there a way to DIY this board?

Going back to default settings / connect twine to new account / delete account

Guido Alphen — Tue, 29 Jan 2013 17:16:43 +0000

Hi,
I'm going to give my Twine to a friend, but don't want my
information linked to it. How do I clear all the account information
linked to my Twine, so it is basically a clean slate for a new owner?

This has been asked in several posts, marked as "Answered," but I can't find an answer.....Ay help much appriciated.

Is a pull-up resistor necessary when using the breakout board?

Martin Cowley — Thu, 16 May 2013 16:58:48 +0000

Hi everyone,

I've had my Twine setup for some time now, and have had it in a couple of roles so far (both involving the breakout board); monitoring a current sensor or float switch on my sump pump, and as an Internet-enabled doorbell. In both cases the switch is normally open, and is closed upon activation (sump pump runs and draws power, sump bucket water level triggers float switch, someone presses the doorbell). I've been using a pull-up resistor between the power and input lines on the breakout board, as per one of the first Twine blog posts (pre-shipping I think, so a while ago) about setting up a photoresistor. I'm wondering if the pull-up is necessary however, given the Twine breakout seems to have a 4.7K resistor built in, and none of the recent blog posts (e.g. about setting up an Easy button) mention the need for a pull-up resistor. Was this some kind of design change on the Twine, and am I safe using my Twine without the pull-up?

Thanks!

Martin.

How does twine work?

Evans Arnold — Wed, 19 Dec 2012 17:38:04 +0000

Twine arrived but there were no instructions. I figured out own to get it to read but not sure about using the sensors. Do you have to plug in each one. Is there somewhere that gives you instructions?

Stats

David Bock — Sat, 24 Nov 2012 15:36:48 +0000

I'd really love to collect stats so I could graph the results. Was thinking the easiest would be to use the gate switch with the temperature sensor to track how many times my dog goes in & out of his dog door & what the temperature is when he does so. Then I could track to see if there's an increase/decrease of activity to temp. Thoughts on how I can collect?

Germinating Seeds / Moisture sensor - DRY alert

Everett Peacock — Thu, 30 May 2013 14:21:07 +0000

using the moisture sensor to alert me when my germinating seeds get DRY. These valuable seeds need to remain moist during the germinating process and I'm now using TWINE to give me an alert when I need to add water to the dish. (see picture)

Twine hasn't been heard from?

Hans Hong — Mon, 20 May 2013 13:21:00 +0000

Hi,

I have a twine on my garage door that is obviously working and sending alerts, but on the twine control panel, it says it has not checked in for some time. How do I fix this?

Where is the "Wi-Fi signal ... meters"?

Hugh Blair — Wed, 30 Jan 2013 20:08:33 +0000

Although I've updated my Twine - saved my rules and see the new dashboard - I don't see this feature.

Twine Setup / connection issue

Dan Maslach — Sun, 24 Feb 2013 09:49:37 +0000

I can't get my Twine to setup and connect to the internet/network. I follow instructions, I flip flop the twine, but once it gets to the point where it needs to connect to the Twine server, I get nothing, countdown goes to zero. I get the 3 quick flashes on the Twine indicating no connection.. Batteries replaced with new ones as well.

Router doesn't show the Twine. I've tried both static IP and DHCP, disabling all firewalls, but no change. Also added the MAC ID to the router to set it to a certain IP, still nothing.. Router is a Linksys E4500. Any ideas?

Is micro USB port standard ?

Nicolas Hauviller — Thu, 13 Dec 2012 13:51:04 +0000

I tried to plug a standard USB to Micro USB adapter to my Twine (because batteries usually last 2 days) however it seems that the micro USB port of my Twine is much smaller than the standard ones (which are supposed to work with mobile phones, etc...).
Do you have the same issue ?

Cloud Shield output

Cora Albrecht — Thu, 07 Mar 2013 15:59:49 +0000

I am interested in the specifics of the Cloud Shield. Since it is connected to digital pins on the Arduino, is is possible to also receive data from internet applications through the shield? Stated another way, is it possible for the Arduino to be an output device from a Twine program, or is it merely a wonderfully complicated sensor?

Thanks.

Unable to insert mini USB connector

Jonathan Collins — Wed, 21 Nov 2012 10:43:43 +0000

The mini USB cables I have don't fit the receptacle on the twine. My connector has a corner on the side as the side progress from wide to narrow, while the twine appears smooth and oval. Is there more than one type of Mini USB?

Twine support still responding?

David Albert — Wed, 05 Dec 2012 14:33:34 +0000

Is anyone still getting answers from Twine support? I have not heard from them for nearly 48 hours since their last suggestion about how to get my Twine to communicate properly.

Checking if someone is moving my Twine?

David Albert — Mon, 19 Nov 2012 16:39:36 +0000

Is there a general rule that will take care of "this twine is being moved"? I could have 5 separate rules for "on side A", "on side B", etc., but that seems like a lot of work. How about "NOT on side A"?

Breakout board and magnetic reed switch wires

Will Luke — Thu, 25 Apr 2013 09:24:39 +0000

Sorry for the newbie question, but I am hopeless with electronics. I have a cheap (UK) reed switch, four wires: red, black, yellow and blue. I've put them into the breakout board's IN and GND in various combinations but it refuses to close the switch.

Simple question then: which wires go where?!

Connecting to wifi at work

Eirik Knutsen — Thu, 07 Feb 2013 02:24:16 +0000

The wifi at work requeries me to log in with a username and password, but the form at twinesetup.com only has a password field. Is there a way to enter a username as well?

Does Twine support WPA2-PSK with AES algorithm?

Devin Mancuso — Fri, 04 Jan 2013 08:34:26 +0000

I've seen in the documentation that Twine supports WPA2 personal (PSK). Does it matter whether the router is configured to use an AES or TKIP algorithm?

Magnet Variable in HTTP Request Action not Working

Pablos Holman — Tue, 20 Nov 2012 23:19:42 +0000

If I set an HTTP Request rule like this:

http://example.com/?magnet=[open/closed]&temp=[temperature]&orient=[orientation]

Then I get this in my web server log:

192.168.1.1 - - [20/Nov/2012:20:19:00 -0800] "GET /?magnet=[open/closed]&temp=76&orient=top HTTP/1.1" 200 652 "-" "-"

Looks like the variable substitution isn't working for the magnet sensor?
