We’ve seen a situation when the customer’s clock lost a wifi credential for the router in the middle of the automatic firmware update. This blocks the clock from finishing the update and continue a normal operation. The only way how to fix this is to go through a wifi connection process again to let the clock know the network credentials.
Typical symptoms – all digits glowing at once and the LED light on the Photon module on the bottom of the electronics board is blinking green (signalling that it is trying to connect to a known wifi network – but can’t find any).
This cannot be done using the procedure with a power adapter (unplugging during the start-up sequence) as the clock never gets to the startup sequence.
Instead, we need to activate the listening mode manually this way:
- power up the clock
- remove the glass cover
- locate the Photon module on the electronics board – it is close to the rotary encoder on the back of the clock.
- there are two buttons on the module – we are interested in the “SETUP” button – the one closer to the encoder
- with the clock on, hold down the SETUP button for around 5 seconds
- The LED should now switch to blinking blue – the clock is now in listening mode
- take any wifi enabled device (laptop, cellphone) and search for nearby wifi networks – your clock should be listed as PHOTON-XXXX, ZEN-XXXX or Puri-XXXX
- You can now follow the connection process instructions and connect the clock to
