I have received two days ago my new sensor. I am not able to start the sensor to proceed with the installation.
When I press the power button it makes a short flash in red after releasing but does not turn to white , blink or green.
Same effect when I press quickly three times or six times. It only produces a short flash in red. I can not proceed with the installation as my app does not find the Netro wifi of the sensor as it is off. I tried to leave the sensor under solar exposure for a full day with no change in the behavior. Still just a short red flash after pressing the power button but nothing else.
Can you guide me how to solve the problem?
