T110 Contact Sensor does not send closed information to hub at extreme range
Hello,
My new T110 contact sensor works great when the door it is fitted to opens. The app shows it as open and a notification comes through straight away from the app every time consistently. However when the door is closed the unit dosn't seem to send the information to the hub and the app shows the door still as open and no notification is given via the app. Looking at the device when the door is opening and closing there is a double flash from the LED on the unit when opening and a single flash on closing so the device seems to be detecting the event but there is an issue with relaying just the close event to the hub. Can anyone help with that? BTW the Tapo app says the T110 is hardware version 1.0 but there is only V1, V2 etc on the form for this post so I put V1.
Good to know that! It's definitely a useful tip!
If the sensor's signal receiver is placed outside the door, it will indeed have a certain impact on signal transmission when the door is closed, not to mention that in your case, the sensor is placed in a relatively far location.
But one thing that needs to be clarified is that the signal source of Tapo T110 is Tapo hub, and the sensor is connected to Tapo hub through SubGHz frequency, rather than directly connected to the router through WiFi. Therefore, if you have any TP-Link SubG devices that need to be placed in a distant location, you can try to adjust the position of the hub so that it can receive a good signal from the router WiFi and provide a stable signal source for the SubG device.
