I am new to homeassisstant. I am migrating from Vera due to lack of support from Vera and reluctance to try Ezlo…
I am now using a Nortek/GoControl Husbzb z-wave stick plugged directly into a NUC running HA in a Virtualbox VM. I use Z-Wave JS UI to program each of the devices on the network. It works very well. I am also learning YAML.
Migration has been relatively straightforward so far, but my smarthome has some old Evolve LTM-5’s and I have discovered two things about these switches:
- The programming in HA for these switches is incorrect. They are defined as a wall mount accessory switch rather than scene controller which is what they are in fact.
The actual value that changes when the LTM-5 switch is toggled up or down is Basic (0x20/32) or command_class 32, not SwitchBinary (0x25/37) or command_class 37.
When toggled on, the value of the command class 32 is 255. When toggled off, the command_class is 0. A few seconds later the value becomes 99 meaning the device is now waiting for a further command.
Currently, there is no way to program the LTM-5 by reference to command class 32. The result is that there is no way to set up a trigger. This is a problem given this device is supposed to be a scene controller (which looks like a light switch)
IMHO, HA needs to add as an option to the trigger menu item “Value change on a Z-wave JS value”, the ability to trigger if command class 32 changes from 0 to 255 or from 255 to 0.
- Notwithstanding this issue, I discovered that users can still LTM-5’s to the system by adding an entry to the group settings for the device. When first installed, the device is grouped only with the controller. But if you add a second group entry linking the LTM-5 to the device you want activated, the controller works fine and it activates the second device. For example, using Z-Wave UI to program the device, select the LTM-5 device, select the Groups menu, and click on ADD. The endpoint will be the controller, in my case endpoint 0. The group number should remain group 1. The target node should be the node number of the device you want to associate.
In my case, the LTM-5 is assigned node 10. The device I wanted activated when the switch was toggled was Node 5. To associate the two, I added a group entry with endpoint 0, Group 1, and indicated that the target node was Node 5. It now works perfectly, at least for now.
