I have just completed a new upgraded version of EchoGarage. New features has been added like detection of the car presence using an extra HC-SR04 ultrasonic sensor and parking assistance with the aid of a nice neopixel led ring!
You will find detailed instructions here.

thanks, I am looking forward to your post.
I am also interested in adding a dht22. Could you please share the details of your project (code modifications, DHT22 version, library, pin diagram etc.)?
Have you also made changes on opensprinkler UI or you just use blynk app?
All these could be very useful for users with little programming experience like me.
thanks, this is a useful information.
Thank you Ray,
where could I find the technical specification of OG board. What is the voltage output of relay?
Can I use the on-board relay to switch on/off for example a water pump?
