Telegram one Bot, multiple receivers, no group

Hello there,
I’d like to have one Bot for each household device. For example a washing machine bot and a dryer bot.
Is each bot able to send messages to multiple users without creating a group? For example the washing machine bot sends all messages to me and another person. Can I just put multiple chat id’s in telegram.cfg or do I really need to create two washing machine bots (one for each user) then?

I just created a group now, as only the first chat id is used when there is more than one in the config file.
