OK! Thank you for the information. Understand to avoid having to do a reset, wise to ensure host is correct before eliminating all the "0.0.0.0's"

I'm attempting to use an encrypted username and password with PHP in a statement as follows: file_get_contents('http://123.12.123.456:99/getall.cgi/dXNlcm5hbWU6cGFzc3dvcmQ=') (Encrypted 'username: password' is dXNlcm5hbWU6cGFzc3dvcmQ=) (also the space after the colon is to eliminate an emoji...

Perfect.  That will work.   Thank you for your advice.   Frank

I need to reset the counter to zero on a WC8 board through the use of PHP.  The board has the newest FW.   Does anyone know what the statement would be?   I'm thinking to send something like: http://192.168.1.15/api/setcounter.cgi?value=0;   Thank you!

I did sent mine back for an upgrade in June of 2013 which updated the BRE board to PLC.  I didn't realize that made it updatable.  The hardware is 2.0.2.  And the firmware says Version: v03.01.17d. I didn't find anything on the webcontrol server regarding firmware upgrade.  Maybe the board's...

  I've always assumed the timing allowed a compromise between sensors at various distances from the master.  And the delay had to do with ensuring the returned pulses had a chance of falling in sync with the master's timing.  But you're saying, there is no need for that timing/adjustment.    Are...

Good information!   So what do you do to fix the sensor failure?

Every 5 minutes I need to read the count on input 1 of my wc8.  If I could then reset it to zero, I wouldn't have to look up the previous 5-minute count because I would know it had been set to zero.   In order to do that, would I have to run a PLC script after the read?   Thank you...

No reason for you to fight success!  I believe I have a single ds18b20 working reliably at the end of a 50' piece of cat5.  I put a 20 mf cap from ground to the Vcc line and a 4.7k pull up at the end.  I figure I'll let that simmer for a bit and then attempt to put a second ds18b20 not far from...

Well....  I am glad you made the discoveries.  But hate to hear what they were.  Right now, I have a new record: one ds18b20 operating over 50' of cat5 for a day and a half on the wc8 board, which is an old one - I now assume it is one of the ones the people gave up trying to use.  But I think I...

Thank you.  I'll experiment. The following article has a good discussion of slew rate considerations. https://www.maximintegrated.com/en/app-notes/index.mvp/id/148

Do you have any starting values for the two ends?  At the far end, the loading resistor would have to go between the Vcc line and the data line in an effort to keep the Vcc as high as possible. At the board end, perhaps the RC could go from the data lead to ground.  Does that sound right?   When...

I've tried three different types of ds18B20 temperature sensors at the end of a 50' piece of cat5e cable.  The cable seems to be of high quality as do the sensors.  Typically a sensor will read OK for half an hour or so, then it stops responding.   There is just one sensor at the end of the 50'...

Four years later...   Has anyone been able to update this procedure for Homeseer HS3 and windows 10?   Things go well until I get to: Homeseer.cls string properties -- Location:  "Run Application on this computer" is greyed.     And in vb.net, when I try to create an object: "Dim HS =...

That's correct.  With Javascript, that is the primary consideration.   I'm currently using jQuery ajax script that uses a little short php proxy server.  It is working pretty well.
