I am trying to use 2 INA219 current sensors, with one connected and at address 40 it works fine, when i put a second one on the bus with a different address I just get a error cant communicate with device message, but the first sensor still works okay?

Cool.  
What node are you using to the sensor?  
Maybe a example flow would be nice.

If you look at the node on the Flows tab ([node-red-contrib-easybotics-ina219-sensor](https://flows.nodered.org/node/node-red-contrib-easybotics-ina219-sensor)) you will see that it hasn't been updated in over two years. If you then go to the [GitHub page](https://github.com/easybotics/node-red-contrib-easybotics-ina219) you will see there are seven open issues and two opened in since December of 22021 that have never had a reply.

AND, if you click on the authors name (easybitics) you will see a link to the website [http://www.easybotics.com](http://www.easybotics.com/) and an email address.

You could try reaching out to the author and see if they are still maintaining the node.
