[APP][Pro] ELKO Smart (deprecated)

Hi! Have the v5 homey fw. And try to connect the Elko super, did it with success with the older version, but with the new, nothing happens when I try to add the thermostat. Is it possible that fw version on the thermostat must be updated, the base card is v. 18.20 with a running v. 1.2.5R.
Please help :raising_hand_man:t3:
