Show us the raw sensor data under the dev tools. If your sensor currently has a properly configured unit, you should have the option to change the quantifier and precision.
If you click on more-info for the lifetime_energy_1_1.1.1 sensor, is there a unit of measurement dropdown where you can change to Wh ? This is one of my energy sensors in kWh, there is an option of Wh
Ok, I get now what you’re doing. I’ve run into the same issue recently. If you want to display the same sensor in different places, but with different units, you can’t do it with this setting. You need to make a second sensor, based on your first one, and set it’s unit to what you want.
If someone has a better solution, I’m keen to hear it.
