Honeywell TCC - TCC Timing Out

skunkiechris · April 26, 2017

Hi,

I just added a TCC thermostat to Nodelink, and am getting pages of timeouts trying to connect (it never successfully connects.) I turned on verbose logging for the thermostat, and this is what I got:


2017-04-26 19:11:07 - TCC Login Error: The request timed out [hwstat2017-04-26 19:11:08 - TCC Data: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Any ideas?

I recently installed Nodelink and added a Honeywell TCC thermostat, and am also seeing occasional errors logged such as "TCC Get Error: The request timed out"

I am seeing the same timeout error as the OP

And I never see data updated in the ISY node.

This is at our vacation home which is on Satellite internet, so there is more delay, like >650ms ping times, but I never have issues accessing the tcc web site on the local or remote networks.

Does this use the same REST Timeout setting, or can one be added for the Honeywell?

larryllix · October 27, 2017

Jimbo. I was having the occasional timeout or failure with the ecobee3 (cloud API) and increasing the timeout provided slightly, helped immensely. Trouble is when you get errors it seems to come in floods for a while then it goes back to being good for a week at a time.

A settable timeout for each device would likely be a good idea, especially for cloud dependant responses. I assume once a response is had it all goes about it's merry software routine way anyway making no delay for other tasks.

Jimbo.Automates · October 27, 2017

Thanks Larry, I did increase that timeout but didn't help. It's been running for a while now and has not been able to update. Maybe the NodeLink Honeywell TCC isn't working anymore? But I did get it to work using a python script found on github.

Scott has a Honeywell IIRC but I think he has it hooked up to the CAO Tag system....cloud or cloud maybe? I am not sure how much info could be obtained from that method. Not for switching comm style but for an indication of how well the comms with the stat work.

I had a very low end Honeywell smart stat model for a while, but found it too elementary for my tastes and took it back but...I cannot remember what options were available in NodeLink so I was wondering if the timing you are referring to was the stat API response time allowance or something else. For the few weeks I used the stat and I don't remember any significant amount of missed responses.

The http timeouts for this device are hard coded. Login is 10s, GET/SET are 5s.

I've made the timeouts configurable in the next version. Kind of brutal that 10s isn't enough.

larryllix · October 28, 2017

With ecobee3 using the default 10 sec timeout, I got some groups of errors on some days. Rough guess about 3-6 errors in a grouping over a few hours on maybe every 5-10 days.

When I expanded the timeout to allow 15 seconds I get an error or two close together about every week or two. This could be LAN, WAN or cloud server bottlenecks. I have no way of telling. My guess is the ecobee server just gets overcrowded occasionally due to the error grouping patterns.

The user settability, with warnings and suggestions, should be a good feature.

NodeLink web maintenance pages are getting very user helpful. Well done!

Thanks, hopefully that will do it. Yes, slow satellite internet is brutal out in the boonies.

0.8.4 is out, hopefully it gets you running.
