thanks Alan,
i was suspecting that this issue is caused by the new firmware ,because before the update the problem didn't exist .
sometimes(maybe 1 time per week ) the station freezes and it needs to be restarted , after restart everything works well, so this is why i assumed that is a software glitch.
After all it is not a big problem, but when im not home i cant restart it, i also suggested to add a restart button linked to each station on the website under "my account" to trigger a command to restart it remotely .
