There are instructions on how to fix this “correctly” in:

Believe me I understand how you feel. :wink:
There isn’t an easy way to allow customization yet. Once ST opens up the HTML to allow control then I will allow all sort of customization

I knew what you meant :slight_smile:
That is a lot of work to keep them all in sync code wisw

Anybody have any thoughts? My Nests have been Offline in ST since Friday afternoon. I can still control it via the Nest App so they are actually online. I’m getting an Error 404. I get this is a Nest issue, but is there anything I can do to fix it? (Reinstall, etc). It has not resolved itself. I know others where having the issue and it did resolve itself, but has not for me. I can see that this has come up intermittently and is has resolved itself, but just not this time. Is anybody else having this issue?

So after the original issue that I had where I was first getting 400 errors, then reset my Nest token and got 404s. Now I’m back to seeing this: 9:30:43 AM: error |Nest Manager | nestResponse | A Bad Request was made to the API | (Status: 400 | Error: Failed with status code 400) and I’m unable to control the thermostat. Can someone please help me troubleshoot this?


I just installed this and I can’t seem to figure out how to control my thermostat, I just pulled it into mydevices and it is showing 0 degrees, I’m assuming that’s the default setting. it shows online in mydevices, but I’m not sure if that is true.

Am i missing a step here?

sorry very new to Smartthings.


thanks @E_Sch, I thought I had had that issue before, but couldn’t remember if it had been fixed, or if I had learned to live with it. I only noticed the slider was in Farenheit because I accidentally used it.

I believe I had made the change before, but had overwritten it when I updated all my device handlers back to the github versions recently… I should really put a note in my IDE so I stop doing that.

In playing around with the code snippet from @anon36505037, I wound up clearing all the cooling control-points because I don’t have cooling in my Nest. I’ll probably reset it back to default and use the easy method on the wiki.

Question. Location tracking in ST has become quite cumbersome.

Is there a way in the Nest App to use Away Assist to trigger away mode in ST as opposed to using ST Mode to trigger Nest Away?

So if I enable away assist and tell the Nest app to monitor my phone presence, when my phone leaves I can run an away piston?

I’d suggest supplementing your phone presence by using Life 360 rather than Nest presence, But that is only my opinion.

I don’t recommend using any of Nest’s away assists if you are going to perform any automation tasks via ST.

I would use your phone or life360 presence in ST with the Nest Manager Automation “Nest Mode” to set the location home\away based on a few triggers using ST presence, SmartThings Mode, or a switch.

Can someone please help me troubleshoot my issue? I’m still getting 400 errors and have lost the ability to control my thermostat.

3:14:02 PM: error |Nest Manager | nestResponse | A Bad Request was made to the API | (Status: 400 | Error: Failed with status code 400)

Thanks Robin, I checked and I don’t see any messages and Nest Manager is listed in the connected apps. @tonesto7 is looking in to it for me, I will try to report back the outcome.

Ok I’m a total noob. How do I install this? HELP

I ended up deleting and reinstalling everything. Worked like a charm!

I think where I screwed it up was when I got some message about it not communicating I reset my token or whatever, and NM and Nest never spoke again.

Everything is smooth as can be now (and no Watchdog warnings either). I was dreading re-automating but afterwards I kinda thought it is probably a good idea to rebuild anyway. It went really quickly this time around and I think I probably have a more efficient schedule set up that does the same thing.

One note though, it was mentioned that NM shouldn’t make a room get warmer if it looses connection because the thermostat itself has the set-points. While that is true, if you are using a remote sensor and virtual thermostat with a 5 degree buffer and then NM loses connection with Nest after the vT jacks up the temp to turn it on then your set point is still set 5 degrees higher than where you want your temp to be and will be there until you happen to notice it getting hotter than it should. My use case is I have room that heats and cools much faster than the others and there is actually no supply vents going to the hallway where the thermostat is (which seems pretty damn boneheaded from a design perspective). So, I have that room set at 69. The hallway may itself be 71. When the room gets below 69 the vT cranks up the regular thermostat to 76. If after it is set at 76 NM and Nest stop talking, it, of course, stays set at 76. Since there is no heat directly going to hall it may take a long time to get 76, especially if the door is closed. In that time, the room can get from 69 to 80 or higher. If the door is closed it usually only take about 10 minutes to increase the temp 5 degrees. In that same 10 minutes, the temp in the hallway hasn’t increased at all. So, yeah, there is a condition where a room can get overhot if they stop talking. I don’t know what could be done about that though (other than lowering the buffer but that wouldn’t completely solve the issue), its just something to be aware of.

You can adjust the swing NM uses for on/off to be different than the default.

For sure! That’s what I meant by lowering the buffer. Even with that though, it can still be exacerbated if you have a large difference in one room to the other. Even if the swing was lowered to only a 1 degree swing, that room could jump up 5 or more degrees before the main thermostat registers a 1 degree increase. Obviously that would limit the downside more so than the default 5.

Again, I don’t think anything else could be done about it. There is only so much you can correct with something smart when you are starting with a dumb and imbalanced design like my house. I’m just pointing out how a room could get hot without NM communicating with Nest (and did happen to me actually) so one just needs to be cognizant of it. Also, I imagine this scenario taking place being extremely rare to begin with.

Otherwise though, I have no idea how I would be able to manage the temps in these rooms without NM. People lived here before me did it somehow, but I bet it was a real source of frustration for them.

I’m not sure I’m asking this in the right place, but, I’m curious about creating a button for the HVAC fan. I know I can control the fan via NM in the ST app, but I’d like to have a button on Smarttiles - preferably with a preset run time. Meaning, I’d like to just hit the button and have the fan run for 15 minutes (or whatever).

I know there is a HVAC fan automation in NM but I’m looking for a manual way. I haven’t gotten into CoRE yet but is this something it would do? Can I create a virtual switch that will run the fan for whatever preset time (like what is in the Nest app) and then create a button that I put on Smarttiles?

Most surely involves a virtual momentary button and CoRE. Some searching will find you the bits to make this go.
