I think you are using the custom integration (custom_components folder)...

Not sure what this means.  Here is my setup:

configuration.yaml

####################################################
#                   ISY 994                        #
####################################################
isy994:
  host: http://172.16.5.251:80
  username: !secret isy994_username
  password: !secret isy994_password

And the integration:

 

I do have an isy994 directory under the custom_components folder.  My question is, what do I do with it?  Delete it?

@shbatm @bdraco Thoughts on this?

Fixed the issue by changing out 

FROM: VOLT 

TO: ELECTRIC_POTENTIAL_VOLT

for 2 cases in the const.py file; line 101 and 398.  Not sure why this is not updating with the core.

Make sure you remove the ISY994 addon from HACS and/or remove the config/custom_components/isy994 folder. Everything from the custom component is in the current version of the core integration.

also fixes the issue... and probably the best solution.
