Finding valid Automation states?

I have a CT101 Thermostat that I am trying to automate the switching between preset modes of using the electric heat pump and the gas furnace.

I have been successful in setting up an automation to enable the gas furnace buy setting it to

`
service: climate.set_preset_mode
data:
preset_mode: Auxiliary


But I have not been successful in being able to switch back to the electric heat pump as I get the error
`
Stopped because an error was encountered at February 26, 2023 at 5:34:29 PM (runtime: 0.01 seconds)

Received an invalid preset mode: None

I have tried setting the preset mode to the following values, but they all result in the “invalid preset mode:”; None, Primary, Heat and 0.

How do I tell that the valid states are so I can switch between the 2 modes?

Note: I am able to successful switch between the 2 preset modes by going under the device details and changing the preset modes successfully, I just can’t find the value to use in the automation. The device details show a value of “None” when the permission isn’t allowed.

HAUI>> dev tools >> states >> choose climate.yourdevice

I think you may be calling wrong service but look at above and it will likely be obvious if true

@tmjpugh , thank you so much, the states UI was exactly what I needed! I am obviously new to HA and hadn’t realized what the “states” tab contained.

For my particular problem, the valid states for preset_mode are “none” and “Auxiliary”. Apparently it is case sensitive as I was using the value of “None” which resulted in the error.
