hi all, previously it was impossible to accurately control multiple groups from a single button if any of these groups were controlled elsewhere, as the 'toggle' microfunction would literally toggle whichever state that group was currently in and flip-flopping would occur. however, it appears in the latest installment of toolkit (1.10.6) and with the use of the newly released 2000 series switches firmware that there has been some progress in this field. i say 'some' because it is still not perfect. i tested a single button slimline switch, with the new firmware, programmed to control 4 group addresses concurrently. i had a second 4 gang switch controlling each group individually. when all addresses are on (or off) the single button will toggle them with no issue, as expected. when 1 of the groups were on and the single button was pressed the others would come on. so far so good. i did run into some issues when the 4th group was on with the others off, and this is where i started to get confused. up until this point of the test it would have appeared that the toggle function would replicate the last known state of any of the controlled groups. however, with the 4th group scenario mentioned above, when the single button was pressed the others did not come on. instead the 4th group turned off. there were more and more increasingly bizarre, and apparently random, actions occurring when 2 groups were in opposite states to the other 2 and when i changed the function of the buttons to dimmers, let's just say i didn't expect to see disco lights on my test bench ;) is there any scope in future releases of toolkit/firmware versions to have this working perfectly? as i said, some progress has been made which is great, but this operation still has its flaws. if anyone knows a workaround i'm all ears. cheers, reece.
