Several devices stopped responding

[deco]

I found that I suddenly have 4 devices (2 outlets & 2 dimmer switches) that no longer respond to either my hub or my USB controller/indigo.
I've tried everything I can think of - turned breakers off & back on, factory reset etc. They simply won't communicate. Deleted one switch from Indigo and attempted to add it again - 'no response from device'. These devices all work manually fine, just no communication. Also, they're in different areas of the house.
This stuff has been stable for a couple years - nothings changed. Frustrated!

If you do have 2443 Access Points. The hardware revision 2 versions. Are built on the same main board as the 2413S/U PLM. They have a reputation of failing after two years old.
I had both of my 2443 Access Points fail. I did rebuild the power supplies in both of them and they are working again.
