Just for reference, I received the automation IP Module Firmware from AAP named PSTNETH_CONTROL_210_3628.apx which is exactly the same version as the one mentioned in the pinned post at the top. Installed firmware onto ESL-2 APP POD with D-LInk cable and configured static IP on the module.
Installed custom component using HACS and used variation of sample config in HA. restart all sensors are there and alarm panel showed up in HA managed dashboard.
Thanks for making this integration available
