Weirdness using hand remote in conjunction with HA and ESPHome entity attributes

I’ve just started using ESPHome with a Panasonic (HZ25TKE) air-air AC/heat pump. Most things are working as expected, but I have some thoughts regarding the following:

1 - When I use the regular hand remote to control, for example, the fan speed, it shuts down the unit (like power off). The same thing happens for any function on the hand remote. As a side note, this also occurred when I was using an integrated IR remote like the Broadlink.

Q: Does this happen to all AC/heat pumps in general, where you can’t use the hand remote in conjunction with HA, or is it just something weird with the Panasonic specifically?

2 - Do the attributes that show up under “Developer Tools->States” become available right away, or do I have to enable them using a new ESPHome configuration?

These are the attributes in "Developer Tools->States" for the Panasonic HZ25TKE entity climate.panasonic_hz25tke:
