Configure the entity values

Hi, I’m trying to create a new custom integration and need some help.

Goal of this integration: Create a list of subscriptions (for example for netflix, cellphone, insurances) so I can store information about the contract. So I can create automations on when a subscription is coming to an end and I can renew. For some subscriptions (energy contracts for example) you will get signing bonusses so that is good to have.

I have created some integration where every subscription is a Device and when I click on the device, I see all properties (entities). I want to have a possibility to update values of the subscription via the UI (not the developer tools). Anyone knows how I can manage this?
