 ### Notes
 
-- All "Original EleksTube" clocks sold after July 2022 are "Gen2" versions. Refer to the [Blog post on EleksTube website](https://elekstube.com/blogs/news/instructions-on-elekstube-clock-for-gen2-systems) for more details.
 - **EleksTube IPS Clock** is the original model created by the inventor in 2021. There are now many similar designs and clones on the market with varying hardware modifications.
-- Newer versions from EleksTube, such as PR1 and PR2 or Pro, are based on the base Gen2 version and sometimes called Gen3, because the original firmware version is already at 3.x for them. The base version is now officially called "**EleksTube IPS Classic Edition**"

Otherwise, all settings will need to be done manually.
 
 `#define MQTT_CLIENT` is used as a unique device name (i.e. it should be different if you have several IPS clocks) and is the "root" part of the topic for all entities that will be interacted with via MQTT.
