Hey, I just installed an ERV in my house, and looking for a good way to visualize it in Home Assistant. Your card looks like just the thing!
My unit doesn't have any built-in telemetry, although I do have temperature sensors on all the ducts. Is it possible to make the RPM/fan percentage/etc sensors optional in the card configuration/visualization? This would be great :)
Based on the card graphic it is not obvious which way is the house and which way is the outside. What do you think about adding icons on the left/right of the card to indicate which way is which. Maybe mdi:home vs mdi:sun-snowflake, or some such?
The units of the temperature sensors / climate entity are not respected. The card seems to always show C even though my indoor sensors are F.
It's not really clear what the climate entity is used for, or what the colors in the card's airflow "arms" mean. Consider documenting this.
Thanks again for making this useful card!
I am using the Flexit Bacnet integration, which doesn't provide summer mode, or bypass mode options. The system doesn't have such a feature.
Missing out these options causes an error which is only visible in the developer console. The graphic in this case does not show at all.
It would be preferable if the erhv card could detect that the attributes are not set and not display the icons for the missing attributes.
For now I am using the heater mode for summer and bypass modes.
