Solution Smart Action: T310/T315 Temperature or Humidity Automation Doesn't Take Effect
05/15/2024 Update Delete solutions for the special cases where the automation does not take effect immediately if T310/T315's current value has already reached the set threshold or range when creating the automation.
This Article Applies to:
Tapo T310
Tapo T315
Issue Description/Phenomenon:
If you are experiencing issues with the automation created using Tapo T310/T315 and it is not functioning as expected, please check if you fall into one of the following situations.
To ensure a proper understanding of the activation logic employed in Tapo Automation for the Temperature and Humidity sensor, it is essential to take note of the following:
If you are utilizing temperature or humidity changes from the Tapo T310/T315 sensor as a trigger for your automation, please make sure that the changed value must cross the set threshold to activate the automation as intended. If the value is equal to the threshold or the changed behavior does not match the set Trigger condition (e.g., "Over" or “Below"), the automation will not be activated.
For example:
Creating an Automation using Tapo T310 as the Trigger device: When T310 temperature over 20℃.
| Changes | Automation Activated? | Note |
| When creating/saving the automation (Current temperature 25℃) |
Yes |
When saving settings, the Tapo App verifies the current temperature/humidity data against the automation settings.
If the current values meet the trigger conditions, a pop-up window will prompt you to either execute the action immediately or skip it. |
| Rise from 18℃ to 22℃ Rise from 20℃ to 21℃ |
Yes | / |
| Rise from 18℃ to 20℃ | No | The changed value (20℃) equals the set threshold, it does not cross over 20℃. |
| Rise from 21℃ to 25℃ | No | Not the set behavior: Temperature (cross) over 20℃. No temperature crossing behavior occurs.
|
| Drops from 25℃ to 19℃ | No | Not the set behavior: Temperature (cross) over 20℃. |
Troubleshooting Tips
1. Ensure device firmware, Tapo hub, and Tapo APP are updated.
2. Check if the automation rule is set correctly. (Trigger and Action device, trigger value, Over/Below, Effective time, etc)
3. Check if the detected value is updated in time in the APP or on the screen (For T315 only).
4. Check the signal strength on both Tapo sensor and the hub. Adjust device's location if the signal is weak.
- For the Tapo sensor and H100: go to device's settings page ->Device's Info -> Click the signal icon to show the RSSI rate.
- For the Tapo H200: go to device's settings page ->Network Connection -> Click the signal icon to show the RSSI rate.
- Switch H200 to ethernet connection if it was wirelessly connected.

thanks, i think i had the settings wrong anyways, looking at the automation one its layout of settings was different from mine.
in the end, i did what you did ( automation - then just reversed it - as its for a humidifier, i want it to be dehumidfier )
thanks :)

Hey @Fudgeybutter
I suspect your issue is with the logic.
1st - the "when" section must have only the triggering condition. Keep it with "humidity above 60%" and nothing else.
2nd - keep it simple in "if" section. You can remove everything that is there, but in case you really want to use it, you can add "dehumidifier is off" to condition the automation only when the device isn"t already on.
3rd - the "then" section is the automation outcome. What do you want from it? The "dehumidifier - on" and also the "notification".
I'm attaching an image from my automation to trigger the dehumidifier on.
Create a similar rule to turn off the device.
Hope this helps 🙏

Below is 2 rooms
1 with dehumidifier
1 without
no heating in any room. natural heat. crazy how much 20% more humidity changes the temp of a room.

I can tell you EXACTLY why your's isn't working! Why have you got Humidifier ON and Humidifier OFF as TRIGGERS? They should be ACTIONS.
