Hubitat Integration Help


I’m new to HA, apologies if this is posted incorrectly.

I have been using Hubitat. To date I have installed the integration with some success and am able to see most of my devices. My aim is to leave Hubitat doing the automation and produce an enhanced dashboard using HA, including devices not supported by Hubitat.

I am having trouble with Hubitat Variables. They are in the HA device list but the entities are disabled. I can enable them and they then appear as variables.

Question 1: Is it possible to enable the Hubitat Variables entities by default?

Question 2: Are the variable entities ‘read only’ and could they be ‘resd/write’.

All advice welcome
