The L020 panel doesn't react to signals of accessories.

When the L020 panel doesn't react, doesn't react stable or seems to have a short range.

This might be a solution:

1. Pull out the power plug out of the L020 panel.
2. Pull out the batteries.
3. Leave it for about 10/15 seconds without any power.
4. Put back the power plug.
5. Test the accessories which didn't work before by triggering them.
