Hi Ciceron, Can you share the full log file? The message seems to say something about the hexToBytes function, which is used to convert the “address” setting of your Thing to a byte. But from the portion you posted I can’t see what’s going wrong. ---

Hi Ciceron, I found the following line in the log file: java.lang.NoSuchMethodError: org.eclipse.smarthome.core.util.HexUtils.hexToBytes Actually, the hexToBytes method is a method that has been added to the openHab snapshot version only a few weeks ago. The fact that the method cannot be found could indicate that you are not running on the latest snapshot version of openHab, either because you are running on the Stable version, or because your Snapshot version is from before the addition of the hexToBytes method. If you are running on a raspberry pi, can you try to switch to the latest snapshot version using openhabian-config -\> openHAB related -\> openHAB unstable? ---

Ok, that explains it, the hexToBytes method has been added on 31/03/2018 🙂 You can find the latest snapshot version on CloudBees: [https://openhab.ci.cloudbees.com/job/openHAB-Distribution/](https://openhab.ci.cloudbees.com/job/openHAB-Distribution/) ---

Hi, You shouldn’t install anything from the iot market, because the version from the iot market is still an old one. Just put the jar in the addons folder. If you see the error “Unresolved requirement: Import-Package: [gnu.io](http://gnu.io)” in your log file, you can try entering “feature:install openhab-transport-serial” in the Openhab console. This should explicitely install the package that is currently missing… ---

Hi Ciceron, Here is an updated version that should fix the slider behavior: [https://we.tl/fFjq594FSp](https://we.tl/fFjq594FSp) Regarding the ON-command, can you check the Build number of your VMB1DM? The command that is used is available since Build 1006. The VMB8PB and VMB6IN have “trigger-channels” that can be used in rules to make openHAB react to changes on these channels. (See [Rules - openHAB 2 - Empowering the Smart Home](https://docs.openhab.org/configuration/rules-dsl.html#channel-based-triggers)) ---

Hi Ciceron, From your previous post I assumed the maximum dim value for the VMB1DM was 64, so what I did in this version is: - When sending a packet using the following value as dim value: (slider percentage / 100) \* 64 - When receiving a dim status setting the slider at the following value: (dimValue /64) \* 100 Any idea where it goes wrong? The ON functionality wont work on build 702, as it requires at least build 1006. But once the slider is working, you can easily achieve +/- the same behavior by creating a virtual switch item and a rule that sets the dimmer value to the wanted ON-state (e.g. 100%). What do you mean by the VMB8PB and VMBIN triggers not being detected? Do you see the trigger-channels in openHAB? Is there anything related to these channels in your log file?
