IoT OTG for Raspberry Pi

Allows you to control your home using Raspberry Pi's and Google Assistant, Siri, and Alexa by texting from 4 different numbers.

Install this app on a Android phone, go to application manager and allow it to interact with received texts.

Then open app, go to settings and enter what phone numbers you will allow this app to take actions from. Then go to settings and add a device (name, ip address, gpio pin number).
Then on the phone you have added to allow to control your Raspberry Pi's create a contact with a name easy to remember (Jarvis) and assign the phone number of the phone with this app installed.

(All of this can be done on the same phone to allow you to speak to Google Assistant to control Raspberry Pi's, You can tell the app to accept texts from the same phone it is installed on).

Once you have the contact created you can say:
Ok, Google, Text Jarvis
"What would you like to send to Jarvis?"
