Hi Matthew,

Could you please let us know your smart phone brand and type? By default, Netro does not require password every time.

Thanks,

After a winter, I set mine in the sun during the days for 5 weeks and under a regular light every night. After 5 weeks, I got one to work (I have 3). According to the device status, after 5 weeks of charging it achieved 8% charge. For the other 2 I next plan to explore replacing the batteries ( they appear dead anyway so if I break them trying to replace the batteries I'm no worse off)
