Welcome,
What I would like to address in my home automation is adding my intercom to the collection of smart devices in the Home Assistant environment. As I live in a block of flats, I have to rely on what is there, and any intercom replacements or adding others are completely out of the question. The intercom used in my block of flats is a Laskomex EC-2502AR int. I have searched all over the internet and there is no AIO solution which will allow me to simply replace my uniphone with one which simply works like the one I have and, in addition, allows remote operation, such as answering the intercom, two-way conversation or opening the door, all from the Home Assistant. The PBX and uniphone connect via a digital signal and there is no decoder to solve my problem, and from what I'm reading, the only option is to connect in parallel to the uniphone via ESP32. Do you perhaps have any ideas on how to accomplish this? There are quite a few issues to consider here, such as door open signal, handset up/down or two-way audio. I won't hide the fact that the idea is ambitious for me and maybe the manual skills are quite good, yes, the knowledge in electronics is limping along. I have not found anyone who has undertaken something like this and described it in their tutorial, so maybe there is someone here who has done such a project and knows step by step how to do it. I ask for your great understanding and will be extremely grateful for any suggestions and help, even the smallest one, as this is an issue that has been bothering me for a few days now and does not allow me to sleep peacefully.
AI: Do you have access to any technical documentation or diagrams of your Laskomex EC-2502AR intercom (e.g. description of leads, communication protocol, service manual)?
I do not have.
AI: Which functions are most important to you to start with - do you primarily care about door opening with Home Assistant, or also audio support (two-way conversation)?
I care about two-way audio and door opening.
