Marc, I've not seen this on the Android App current Version 3.2.1 and latest 1.6.0 firmware :(
Also needs to work on Apple to avoid the disadvantage for my wife...
Is it just me, I saw a line of red text on the top right corner of every devices shown on the app. Written "Control by LAN" didn't manage to get a screenshot as it quickly disappeared. Was wondering are they in the progress of working on the LAN network.
AK, I am up and running again - I didn't need to power cycle but they didn't all resolve at the same time.
I'm not sure how regular, I've only had the devices 2 or 3 months - second occasion of failure.
The last time was longer and was related to waiting a server up-grade. Victim of own success? Broadly, I've found the devices good but I'm considering a 3rd party software flash to manage via a Raspberry Pi locally.
It's the servers (again!)
