Let’s take it a step at a time. First you need to verify your device is joining the SmartThings ZigBee HA network. With the xBee you can look at an association parameter to see if it joined the network. On a TI chip I don’t know what the equivalent command is. But once you find it it will tell you if the hub allowed you to join the network. If your device isn’t allowed to join the ZigBee HA network than most likely you have a security setting messed up or a protocol setting set incorrectly. You will need to address that and try to join again. Once you have your device physically joined to the SmartThings ZigBee HA network we can go onto the next step of getting your device visible in the SmartThings cloud.
