Below is a list of common causes of problems with Shelly products.
The list is continuously updated, but does not claim to be complete.
|Actuator||problem / error pattern||Remedy|
|all Shelly||Shelly cannot be integrated into WLAN or app, does not provide any data via MQTT||Router incompatible?
Shelly and (partially) incompatible network components
Problems with integration into the SHELLY CLOUD app
Tips for beginners B2 (for WiFi)
Shelly doesn't like hidden SSID or special characters in it.
|Shelly cannot be found in the app despite a positive message in the room||possibly the Shelly is in HIDDEN DEVICE, check and correct the assignment there via "Edit" (pen)|
|Shelly is switched on, pops and the fuse falls, smell of burning (this may also only happen a few days after commissioning)||Switching voltage on the SW is on a different phase than the supply voltage, thus 400V on the Shelly -> check and correct connection|
|Problems with the glow lamp in the switch or button||Find the solution here (German thread)|
|Error message: Bad default state, botton type combination||Adjust Power on default mode|
|Shelly should switch itself (via Actions)||To do this, the IP address in the http request must be replaced by "localhost" (without quotation marks).|
|all with relay contact||Consumers stay on even though Shelly is switched off||The cause are mostly sticky relay contacts. This problem arises from very high inrush currents.|
Remedy: Install inrush current limiter.
