How are you measuring CPU Load/ CPU Usage?
You can use the system monitor integration. Use in your configuration.yaml this entries:
# SystemMonitor
- platform: systemmonitor
resources:
- type: processor_use
- type: load_1m
- type: load_5m
- type: load_15m

Thanks, just found the docs here:
I’ll give it a try.
I was using ‘iostat’ to monitor CPU load but found it wasn’t very accurate for me.
Would you mind sharing your UNRAID config.
I am running HASSIO in a VM on UNRAID but would like to monitor the server conditions.
Thank you

How is your sensor coded for potential breaking changes?
Made an update for more system informations. Maybe they are interesting for some guys.
Here the code in configuration.yaml:

@LogisticaLux nice work!
would you mind share how did pull the data about the snapshots?
can you share the configuration code?
Thank you!!
@yoni3210 Thanks! 
Just install the addon Hass.io Google Drive Backup than you have those sensors available.
After the install put a check on the desired sensors.
Would you mind sharing the script. I have been a heavy user of nextcloud for 4+ years and this would be a big help in monitoring my connection.
Thanks

Would you mind sharing the code fot the Unifi Device. I have tried something similar but could not get it to display properly.
Thank you.

Look nice. Quick question, how do you retrieve the wifi and radio informations from WAP.
Thanks @mistrovly!
I retrieve the info through SNMP using a few different OIDs:
Model 1.3.6.1.4.1.41112.1.6.3.3.0
Firmware 1.3.6.1.4.1.41112.1.6.3.6.0
Total Memory 1.3.6.1.4.1.10002.1.1.1.1.1.0
Free Memory 1.3.6.1.4.1.10002.1.1.1.1.2.0
CPU Load 1min 1.3.6.1.4.1.10002.1.1.1.4.2.1.3.1
CPU Load 5min 1.3.6.1.4.1.10002.1.1.1.4.2.1.3.2
CPU Load 10min 1.3.6.1.4.1.10002.1.1.1.4.2.1.3.3
Uptime 1.3.6.1.4.1.41112.1.6.3.5.0
For the ESSID details it depends on which one you want. The MIBBrowser I use I put in 1.3.6.1.4.1.41112.1.6.1.2.1.6 then did a GetNext operation to view the values of 1.3.6.1.4.1.41112.1.6.1.2.1.6.1 through 1.3.6.1.4.1.41112.1.6.1.2.1.6.5
Channel Info 1.3.6.1.4.1.41112.1.6.1.2.1.4
Tx Power 1.3.6.1.4.1.41112.1.6.1.2.1.21
Which ever ESSID you are interested take the last number from the OID and append it to the OID for Channel Info and Tx Power and you’ll get those specific details.
For example my ESSID was at 1.3.6.1.4.1.41112.1.6.1.2.1.6.3 so I just append .3 to Channel Info (1.3.6.1.4.1.41112.1.6.1.2.1.4.3) and Tx Power (1.3.6.1.4.1.41112.1.6.1.2.1.21.3)
Hope this is clear

Most of the entities are populated with info directly from the SNMP query. I did have to convert the uptime value I retrieve from SNMP though.
Here is how I converted the time value:
- platform: template
sensors:
ap_uptime_conv:
value_template: >-
{% set time = (states('sensor.ap_uptime') | int) | int %}
{% set minutes = ((time % 3600) / 60) | int%}
{% set hours = ((time % 86400) / 3600) | int %}
{% set days = (time / 86400) | int %}
{%- if time < 60 -%}
Less then 1 min
{%- else -%}
{%- if days > 0 -%}
{{ days }}d
{%- endif -%}
{%- if hours > 0 -%}
{%- if days > 0 -%}
{{ ' ' }}
{%- endif -%}
{{ hours }}hr
{%- endif -%}
{%- if minutes > 0 -%}
{%- if days > 0 or hours > 0 -%}
{{ ' ' }}
{%- endif -%}
{{ minutes }}min
{%- endif -%}
{%- endif -%}

Thank you. I just started to get into SNMP in the last few days. I will have to experiment more with it.
Greatly appreciated and Happy Holidays.

Another question for you; do you configure your snmp at the unifi controller or on at the AP itself
How are you monitoring the ERX?
I configured SNMP from the unifi controller. But it just pushes (provisions) the configuration to the AP itself. When I configure Home Assistant, the IP address is of the AP.
sensor:
- platform: snmp
name: 'AP Model'
host: 1.1.1.1
community: 'private'
baseoid: 1.3.6.1.4.1.41112.1.6.3.3.0
thank you for your reply
