Telegram bots - one user, multiple HA instances

I have been using HA with a Telegram bot at home for a while. I love it. My father had a stroke a couple of months ago, so I created a HA install at his home also. Its main role is to provide help needed buttons at the places he spends most of his time, with a couple of LED indicators and sound and voice notification entities in other locations to let my mother know when he’s activated it. They live next door to me, and I want the system to notify me wherever I am if she hasn’t cleared a call within a certain amount of time. That way, i can go next door or find another way to make sure my mother knows he needs help.

The Homeassistant side started to get twitchy when two HA installs are using the same chat ID. The second one (not doing the talking) will just stop responding, requiring a restart of Homeassistant.

Every tutorial I have seen leads me to the same end: Even though I have two bots (separate API key, user name, etc.) and they seem to work via the android app, web app and linux desktop app, I can not find the chat ID of the second bot. The GetIDs bot and the API call for updates only return the first chat ID.
