Yes, it a Computime thermostat and I am using the normal provisioning procedure. The process is:
1. Check the gateway channel and PAN ID.
2. Open the gateway's network i.e. enable joining.
3. On the Computime tstat, scan for the specific PAN ID on the specific channel and then select and join.
4. The tstat shows the message 'Join unsuccessful'.
Let me know if I should try something else.
