Call Me with Home Assistant, Zoom and Telegram Bot

Using Home Assistant to launch the Zoom meeting and send the meeting Url to predefined contacts via a Telegram bot.

It is a very useful and fast way to initiate a Zoom meeting with just a click of a button and share the meeting link automatically especially for the elderly people who are not used to Zoom but they still can use the tablet.

Zoom App Config

Create a Zoom App and get the JWT API Key and Secret. Please refer to the tutorial below on how you can create and generate.

Select the Zoom app you have created and navigate to Feature and enable the Event subscriptions to setup a webhook.

Setup a Webhook

On the Event types, navigate to Meeting and select End Meeting and Participant/Host left meeting.

Set the Event notification endpoint URL with your Home Assistant (HA) URL. Your HA should be accessible publicly.

Home Assistant (HA) Setup

Create a Switch

We will create a switch “Call me” in HA to launch the Zoom meeting automatically.

Open the configuration.yaml and insert the following line and save it. You need to update the IP address to your table’s IP address. The parameter command_on and command_off will execute the Curl command respectively.

Restart the HA

We need to restart the HA to apply the change.

Navigate to Configuration > Server Controls and click Check Configuration. If there is no error click Restart under Server Management.
