Communication issues with Z-wave and KPL

[deirwin]

I have several issues that I think are related.

1. No longer able to communicate with thermostats (z-wave)
   1. I was able to communicate with a few this morning, but not all, and now, none.
   2. ISY is located approximately 10 feet from one thermostat.
2. No Keypads work for any purpose other than  primary switch - programming and secondary functions no longer work.
   1. I have been having keypad issues for long time, but removed all but 5.  4 of the 5 remaining in system had been working fine prior.

Three incidents that could have impacted things (that I know of):

1. I moved the ISY to a different part of house.
2. I changed the IP address of ISY 6-8 weeks ago
3. Power outage occurred a few times in last couple of weeks
   1. We have automated whole-house generator, but during the last outage, the generator did not start, so we went several hours without power.
   2. Typically after a power outage, I have to manually reset the keypads by pulling tab out for 10 seconds.  This has not helped this time.

I would be grateful for any thoughts on what to do.

@deirwin , Did you perform network heal to your Z-Wave network after you moved your ISY? If not, you may want to do that and see if your Z-Wave communications improve.

I agree with Dbuss in regards to zwave. Before that however, I'd move it back to your original location and see if things go back to normal. If it does, then put it back where you want it then do a network heal.

I responded a few days ago, but apparently did not send...  I did perform the z-wave heal, but it didn't help.  I moved ISY back to original location, and all thermostats almost instantly showed status.  That problem resolved.  KPL issues continue.  It turns out, we still have 8.  3 make a clicking sound and will do nothing.  3 seem to be working perfectly.  1 only turns on its own light, but other buttons do not perform their function.  1 performs functions for all buttons, but lights do not appear indicating they are on...

What are the keypads? Are they the newer dual-band kpls or older Powerline only? Factory reset them, then restore them from the isy
