Home assistant cast setup but for a raspberry pi

Third party integrations

I don’t have any real google products other than 1 google chromecast in the living room and 2 sonos speakers that I turned from Alexa to a Google Assistant just for kicks.

I do, however, like the idea of having the home assistant cast. Needless to say I don’t plan on buying some google home hubs for the house. Therefore, I am wondering how would I do custom dashboards or views for lovelace that run on a raspberry pi with the RPi touchscreen and something like this https://www.adafruit.com/product/3187

I figured I could use a kiosk like browser that runs on startup and hides every menu, but since I am still such a novice on customizing lovelace (currently i just expose everything to homekit and control it via that way or via echo or zwave double tap switches) I don’t know how i would create custom dashboards. I am talking like a bedroom lovelace view that has large buttons

One use case I am thinking of is when a doorbell rings having HA pause what I am watching in the living room via the logitech harmony remote / roku and switch input to chromecast and use HA cast to cast the front door view THEN i have a raspberry pi screen show a large button to open the front door or a record button to deliver a custom message. THis is a use case I am barely starting to brainstorm.

I listen to the podcast which I love, and I did hear that there are still changes happening to lovelace to allow buttons on the screen to be developed which would help HA cast be more fluid. Perhaps this is something that I should also wait for.

Why not just run a web browser on the raspberry pi screen. You don’t need to cast anything.

Well if I understand the difference between a web browser solution vs a cast solution the pages don’t dynamically change with an automation.

If they do then that goes back to my lack of familiarity with Lovelace. The use case I can think of right now is the doorbell one where when the doorbell is rung then the whole raspberry pi screen (whether it’s a browser or a cast type of solution) should change to two big buttons to unlock or send a message while simultaneously my TV can show me the camera view.

There is an addon to programmaticly change lovelace pages in a browser. So put your two control buttons in a separate lovelace page. When the doorbell rings, use an automation to switch to that page.

good to know! Thanks! Didn’t know of this. I will have to play around with this when I get the chance!
