@joacim I have made one more happy discovery. In January, when I bought my six Flic singles I found that every time the button was moved out of range of the phone the bonding was broken. To re-establish a connection it was necessary to do a seven second button press. This was also a killer disadvantage for my intended use.
Now I find that no longer happens. When the button comes back withing range of the phone it automatically re-establishes its connection and a seven second button press is no longer necessary.
This has removed the last major barrier for my intended usage of the buttons and it makes me very happy indeed.
Congratulations to Flic for listening to their customers, being responsive, attending to issues and progressively refining the product. This puts you head and shoulders above the rest.
