Smarther API: Gateway offline


Smarther API is answering “statusCode”: “404”,”message”: “Gateway Offline”

This morning my client application (openhab binding) sent calls every 5 seconds since the gateway was unreacheable, and it is also possible that the 500 calls limit has been exceeded.

Are there any server side issues with smarther API?

In case the API calls limit has been exceeded, the answer is still “404: gateway offline” or is there a specific answer?


Hello AZ,

Do you still have this problem ? We don’t find any issue on our side with the API

Here is the 404 error :  “404”: {
“description”: “Resource not found/Gateway offline: something is probably wrong in your request URL or your thermostat is temporary disconnected from the network.”

If it’s now working, it could have been a little delay issue on our side (but nothing appears in logs) or a temporary issue with your internet connection

hello, everything is working as expected.

i misconfigured API polling frequency and consequently exceeded the limit set at 500/day, as reported in the analytic page under ‘my subscriptions’.

API server apparently answers with 404 when the limit gets exceeded.


i got “500: Internal server error” today, after 6 days without any issues.


nevermind, i just got the email regarding planned maintenance for today

Hi, we still get 500 Internal Server Error, please check issue.

Hi Onofalt,

I don’t see any issue on my side. Can you please give me more info about your problem ?

Hi, I started getting “404: Gateway Offline” approx 14 hours ago. API has worked well for last few weeks.

I’m querying from MS Azure. Weirdly enough, both ping and traceroute to completely fail.


It seems to be OK on my side. Does it still not working ?

Hello Guiseppe,

We had a firmware update yesterday, maybe it disconnected your gateway while making the update. Do you still have the issues ? On my side the API correctly answers

Hello Leslie,

I’m still having a lot of troubles. My app is still having “404 – <span style=”color: #575757; font-family: ‘Segoe UI’, ‘Noto Sans’, sans-serif;”>Gateway Offline” or “408 – Request timeout” error. Even Thermostat app can’t connect to my thermostats.  My wifi and my internet connection are working.</span>


Can you help me, please?

I discussed with the teams, it seems that indeed there is a problem with messages sent to the Thermostat application, causing indirectly issues with the API. They are working to fix it
