Things has been working OK, and the connection is fixed.

But the last week something strange has occured.

During the afternoons, after coming home from work, the slave lamp is giving 0 % of the Royalblue while the master is showing the programmed intensity of app 88 %. All other channels are identical on both lamps.

This continue until the lamps turns off at midnight.

It was a change of -1 at the slave, but even after removing this difference, having a 0 value on both, the lamps are not giving the same light.

Any idea how to fix this?

By the way I have checked the RB channel manually at 100% and this gives correct at both lamps.
