PLUGIN: Honeywell Total Connect Comfort Thermostats

Yes, I also have a problem with the plug-in. And for me it has been running for many years so far
I use also EMEA

Status: Unsuccessful. Error code: 4

Same issue here, as of 2 days ago my plugin suddenly can’t login, I verified that the tcc login works for me on their website and can indeed control the thermostats, just the plugin can’t connect with the error code 4.

Same here started 2 days ago

Same here – noticed this last night.

I tried deleting the plugin, re-creating the device, and even changing my credentials and nothing helped. At first I was seeing “Invalid Token” in the logs, but after I deleted the device and changed my password they just say “HNYWL TCC ERROR: TCC authentication error”. Honewell app and website both work fine.

I am having the authorisation error from the plugin. Running Beta2. Honeywell’s iPhone App is working.

It looks like this is a pretty easy fix. The last firmware updates provide a new version of LuaSec, the library that underlies the HTTP/SSL module the plugin uses (this is an important and necessary update, as the LuaSec module has been way out of date for a long time and is missing ciphers that are well on the way to becoming mandatory). This later version of LuaSec requires that the “protocol” option be set in requests, which the plugin is not doing (and thus causing an error).

I’ve patched up the plugin, and the file is attached below. Someone else needs to test and confirm the fix–it’s working for me, but one data point is worth very little. The author of the plugin needs to integrate these fixes throughout the code as needed for the new LuaSec. I’m happy to confer as needed.

Download, unzip, and send the one file up to your Vera via Apps > Develop apps > Luup files.


EDIT: Updated file to include prototypical fixes for all platforms (EMEA, etc.–I can only test legacy/US) (24.0 KB)

hopefully 7.31 goes to production soon

When you refer to systems running 7.31 and up, what are you referring to? The plugin stopped working for me and I am on firmware 1.7.4452. I tried the new files you uploaded but they don’t seem to help.

Thanks for your work on this!

No, they wouldn’t. I can take a pass at a more comprehensive fix that might also work on older firmware, but as my earlier message says, the old version of LuaSec on firmware 7.29 and prior is in danger of not having ciphers/features that some sites are now requiring as they enhance security. Give me a bit to make a new pass at this for that older firmware, and we’ll see where we end up.

What platform are you using (TCC, Euro, mobile, EMEA, etc.)?

I use TCC, personally. If you can implement the fix for that, I would be much appreciative.

Is the 7.x series of firmware for a different set of devices? I’m on the Vera Edge myself.

7.x applies to all legacy Vera devices (but not Atom or PlugHub). Stay tuned… updates coming…

I am on 1.7.4453 on a Vera Plus and it stopped. If you can fix this @rigpapa, please add the updated Lua file floating around that I reposted in post 772. This fixed missing fan features.

Unfortunately, the original author and the 2nd author are both gone to my knowledge. I wish Ezlo would add native support for Honeywell thermostats like most competitors.

Edit: firmware is 7.0.29 to help clarify

OK. This ZIP file includes all API interfaces with adjustments for both LuaSec 0.5 (firmware 7.29 and below) and LuaSec > 0.5 (firmware 7.30 and .31 except Vera Edge). This also includes the fan-fixed version of the plugin implementation file referenced in the prior post by @Nameless, so this ZIP file contains a comprehensive update of everything (as far as I know) since the app store release. (24.4 KB)

If you all would test please and report back success or fail and your firmware version and hardware platform, that would help get the loop closed quickly.


Just tested this patch, works for me under 1.7.4832 (7.30)

Thank you very much!

Edit: oops, forgot to mention this is on a vera edge

I was too quick with the response. I get an error message after about 1 hour

Thanks for the fix, working now on Vera Plus 1.7.4453, in the US through updating the *_legacy.lua file. Thank you!

It looks like there has been some changes in the EMEA/EU api. Hass, for example, now has a completely separate component for Honeywell EU. The URLs in the current Vera plugin don’t appear to work at all. Unfortunately, I have no way to develop or test for that locally, so it’s a non-starter, I’m afraid, unless someone in the EU with Honeywell devices wants to make the effort.

I don’t know if I can help. Im in Europe but EMEA api as far as I know and if needed I can do some testing. :grinning:
For the time being I’m not able to connect with your new files .
