Our house (I live with 5 roommates) uses a google hangouts chat from our phones to communicate various things. Lately we've been discussing some scheduled things, like a rotation for cleaning certain parts of the house, and I thought it would be useful to have a bot announce the pertinent information about the schedule on a hangouts chat.
I'm wondering what the best way to go about this is.
There are two approaches I see:
1) Make an app using google hangouts API which sends messages at the correct interval, connect to this app, use it to chat.
2) Make a google account for a bot which we connect to the hangout, make it send messages at the correct interval.
I like number 2 because I wouldn't have to interfere with the app to change the bot's code, but I'm sort of at a loss for where to start.
Number 1 seems okay, but I'm also not sure I can connect to a google hangouts app on my phone the same way I can just create a chat with friends.
How should I go about doing this task?
