Why Won't Alexa Control My Ecobee Thermostat?
- Ecobee Alexa skill needs to be re-linked after an Ecobee password change or app update
- Ecobee cloud service outage — the skill depends on Ecobee servers being online
- Thermostat is offline in the Ecobee app (WiFi disconnected or power issue)
Problem Description
You say "Alexa, set the temperature to 72" and Alexa responds with "Ecobee is not responding" or "the server is unresponsive." The Ecobee thermostat works fine from the Ecobee app and the touchscreen, but Alexa cannot reach it. This breaks voice commands for temperature changes, mode switching, and hold settings. The most common cause is the Ecobee skill link expiring in the Alexa app — Amazon requires periodic re-authentication with third-party smart home skills.
Why This Happens in Real Homes
The Ecobee-Alexa server unresponsive error is one of the most searched Ecobee support queries. It is usually caused by the OAuth token between Amazon and Ecobee expiring, not by an actual server outage. Ecobee servers do experience outages 2-3 times per year, but the more common cause is the skill link going stale after a password change, app update, or simply after several months. Re-linking the skill takes 60 seconds and fixes the issue in the vast majority of cases.
Symptoms
- Alexa says the device is not responding when you ask to change temperature
- Alexa says ecobee server is unresponsive
- Alexa cannot discover or find the Ecobee thermostat
- Alexa says OK but the Ecobee temperature does not actually change
- Ecobee disappeared from the Alexa app device list
- Ecobee Alexa skill shows as linked but commands do not work
- Alexa can control other smart devices but not the Ecobee
- Temperature changes via Alexa revert within seconds due to a hold or schedule override
Recognize these? Here's what usually causes it.
Common Causes
- Ecobee Alexa skill needs to be re-linked after an Ecobee password change or app update
- Ecobee cloud service outage — the skill depends on Ecobee servers being online
- Thermostat is offline in the Ecobee app (WiFi disconnected or power issue)
- Alexa skill linked to a different Ecobee account than the one controlling the thermostat
- Vacation Hold or Temperature Hold on the Ecobee overrides Alexa temperature commands
- Ecobee smart home/away detection reverting Alexa temperature changes
- Router DNS issue preventing Ecobee cloud from communicating with Amazon cloud
- Alexa device discovery not run after re-linking the Ecobee skill
Most fixes happen in the first 3 steps.
Disabling the Ecobee Alexa skill and re-enabling it will remove the thermostat from any Alexa Groups or Routines. After re-linking, check your Alexa routines that reference the Ecobee and re-add the thermostat if needed. Also verify the thermostat is back in the correct Alexa room after re-discovery.

Step-by-Step Solution
Verify the Ecobee is online in the Ecobee app first
Before troubleshooting Alexa, confirm the thermostat itself is connected. Open the Ecobee app on your phone and check that the thermostat tile shows a current temperature and says Connected. Try changing the temperature from the app — if you can control it from the app, the thermostat is online and the issue is specifically in the Alexa-to-Ecobee link. If the Ecobee shows Offline in the app, Alexa cannot reach it either. Fix the Ecobee WiFi connection first: on the thermostat, go to Main Menu, Settings, Wi-Fi, and reconnect to your network. The thermostat must be on 2.4GHz WiFi.
Disable and re-enable the Ecobee Alexa skill
Open the Alexa app on your phone. Tap More, then Skills & Games, then search for Ecobee. If the skill shows as Enabled, tap Disable Skill and confirm. Wait 30 seconds. Then tap Enable and follow the account linking prompts. You will be asked to log in with your Ecobee account email and password — use the exact same credentials you use to sign into the Ecobee app. If you recently changed your Ecobee password, the old skill link is broken and this re-link is required. After linking completes, say Alexa discover devices or in the app go to Devices, tap +, then Add Device, then Thermostat. The Ecobee should appear in the thermostat list within 30 seconds.
Fix Alexa says ecobee server is unresponsive
When Alexa says the server is unresponsive, it means the Alexa cloud cannot reach the Ecobee cloud. This is either an Ecobee server outage or a skill authentication failure. First check if Ecobee servers are up: try controlling the thermostat from the Ecobee app. If the app also cannot connect, Ecobee is having an outage — wait for it to resolve. If the app works fine but Alexa says server unresponsive, the skill link between Alexa and Ecobee has expired. Disable and re-enable the Ecobee skill in the Alexa app (previous step). This is the most common cause of the server unresponsive error — the OAuth token between Amazon and Ecobee expired.
Check for temperature holds that override Alexa commands
If Alexa says OK when you set a temperature but the Ecobee reverts to a different temperature within seconds, a Hold is overriding the command. Open the Ecobee app and check the main screen — if it shows Vacation Hold, Temperature Hold, or Smart Home/Away, these take priority over Alexa commands. Tap the hold indicator and select End Hold or Resume Schedule. Then try the Alexa command again. To prevent this in the future, know that Alexa temperature commands create a temporary hold, but an existing Vacation Hold or schedule transition can override it. If you want Alexa to have lasting control, end all holds first.
Fix Alexa not discovering the Ecobee thermostat
If the Ecobee does not appear in your Alexa device list after linking the skill, there are several causes. First, make sure you ran discovery: say Alexa discover devices or use the app. Second, check that the Ecobee skill is linked to the correct account — in the Alexa app, go to the Ecobee skill and check the linked account email. Third, if you have multiple Ecobee thermostats, only the ones registered to the linked account will appear. If discovery still fails, remove the Ecobee skill completely, restart the Alexa app, then re-enable the skill and link again. For Echo devices with built-in temperature sensors, make sure you are not confusing the Echo internal sensor with the Ecobee in the Alexa device list.
Verify the correct Ecobee account is linked
If you have multiple email addresses or family members have separate Ecobee accounts, the Alexa skill may be linked to the wrong one. Open the Ecobee app and go to Account — note the email address shown. In the Alexa app, go to Skills, Ecobee, and check Settings or Account Linking — the linked email should match. If it does not, disable the skill, re-enable it, and when prompted to log in, use the correct Ecobee account email. A skill linked to a guest or secondary account may show the thermostat but lack permission to change the temperature, causing commands to fail silently.
Fix intermittent Alexa-Ecobee failures
If Alexa controls the Ecobee sometimes but fails randomly, the issue is typically network-related. The Ecobee-to-Alexa chain requires your thermostat WiFi, your home internet, the Ecobee cloud, and the Amazon cloud all working simultaneously. Check your router for intermittent WiFi drops — look at the router log for the Ecobee MAC address reconnecting frequently. Set DNS on your router to Google (8.8.8.8) or Cloudflare (1.1.1.1) to avoid ISP DNS failures. If the Ecobee WiFi signal is weak (check Settings, Wi-Fi on the thermostat for signal strength), add a WiFi extender near the thermostat. Intermittent failures after the Ecobee has been online for months usually point to the Alexa skill OAuth token expiring — re-link the skill every 6 months proactively if this keeps happening.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If voice commands stopped working after relinking the account, check that the skill or action is still enabled — relinking sometimes disables it silently.
When asking Alexa to control the Ecobee, use specific commands: Alexa set the thermostat to 72 or Alexa set bedroom to 68 if you have named your thermostat. Avoid vague commands like Alexa make it warmer which sometimes get misinterpreted. If you have multiple thermostats, name them by location in the Ecobee app (Upstairs, Downstairs) and Alexa will use those names. The Ecobee skill also supports Alexa set the thermostat to away and Alexa set the thermostat to home for comfort mode switching.
Thermostat issues that keep returning are often caused by stale backup-battery memory holding old settings across power cycles without the user realising.
