Hello, i have found a very annoying bug in an official dth that is breaking an important part of my automation, please samsung read this carefully and don’t ignore it.
The problem comes from multi metering switch dth that aeotec dual switch uses it by default.
What i’m trying to do is set parameter 123 to 2 and associate an external device to group 4.
I use zwave tweaker to do this,if i leave the tweaker as dth everything works fine, meaning the s2 physical switch won’t control its own load but will control an external one.
As soon as i change back from tweaker to multi metering switch, parameter 123( and 122) gets back on default value, group changes are fine
So it will basically end up controlling my external device BUT its own load turns on/off too.
What samsung needs to check is why the parameter is not remembered and reverted back to its original value.
I have tested the single nano switch from aeotec and i can confirm that same bug is not present and the paramaters values are preserved after changing back to its official dth too.
Here are the exact steps samsung needs to fallow to identify the bug.
I am using smartthings hub v3 UK and the problem is on aoetec nano dual switch last firmware.
-Change multi metering switch to zwave tweaker.
-Change parameter 123 to 2 (bug exists in parameter 122 too) and link your external device to group 4.
-Leave the zwave tweaker as dth and test the s2 physical switch.
-Boom, it works s2 changes the external device while NOT controlling his own load.
-Change back from zwave tweaker to multi metering switch dth.
-Bug appears, s2 will control his own load too even if parameter 123 is set to 2.
I believe there are isn.t any other compatible dth for this device that i can try
