I think if you change those, the ecobee may not know what you are sending when you select auto. Ecobee's command is for heat cool (within the native Ecobee app).
This was discussed before in the parent thread for HADB. "Auto" has multiple meanings and caused issues with the driver. This thread would also be a better location for issues/requests specific to usage of HADB drivers, since I do not think anyone has mentioned @ymerj yet in this discussion. It might be more likely to get addressed or explained if it were posted in the HADB thread.
When I use Heat, or Cool as the settings, the setpoint arrows show up fine. Cofirming the only issue is in heat/cool combined mode.
Perhaps we should put a request to change the HE tile behavior so that it recognizes "heat/cool" as equivalent to "auto" and allows for the setpoints to show? But the issue with that would be trying to map every unique device. So, it might not be feasible.
