You could also create a threshold sensor that will then give you a binary sensor with ON / Off based on the grid frequency / voltage

any advantage doing this instead of using grid voltage  / grid frequency?

The basis of this does use the voltage / frequency. The output is then On of Off that you can use. Its just another way of achieving the same

I have managed to setup HA and SA to talk to each other.  What parameter do you use to identify load shedding?  at the moment i am using if voltages goes below 100v.  I was wondering what is best?

Hey there

I am using a custom card

Code as follows:

type: custom:button-card
name: GRID STATUS
entity: sensor.grid_voltage
show_units: true
show_state: true
tap_action:
  action: none
hold_action:
  action: none
color_type: icon
styles:
  icon:
    - color: |
        [[[
          if (states["sensor.grid_voltage"].state > '210') return 'green'
           else return 'red'
        ]]]
    - height: 105px

You have to install a HACS plugin-in for the custom-card as far as I remember

Im hoping you or someone else can help me here.  I have posted on Home assistant forums, but i didnt get a reply.

I want my lamp bulb (tuya RGB led light) to turn red when loadshedding starts.  My lamp turns on, but it doesnt turn red.  Please see if you can help me:

Tuya Smartlife Eskom sensor plugged in to inverter and Eskom

Tuya relay switch to run standard lamp with rechargeable “Loadshedding globe” - run the relay from a dc ups

Run your Wi-Fi and internet off DC UPS

Now you can use a smartlife scene to automate turning the lamp on during Loadshedding and off afterwards (or whatever other automation you need)

Note using cheap DC UPS is much more efficient than running the relay and Internet off your inverter, so will save your inverter battery.
