| Dec 12, 2016 at 11:40 | comment | added | alo48 | The electric meter send data continuously so it seems it will cause a data collision. Moreover the program won't be able to determine from which electric meter the data comes from. | |

| Dec 12, 2016 at 11:29 | comment | added | User323693 | how about connecting another opto? Pin 4 and Pin 3 of second opto can be shorted with Pin 4 and 3 of first opto. assuming data collision is not an issue | |

| Dec 12, 2016 at 11:17 | comment | added | alo48 | To read the signal I use the RXD GPIO pin and it seems that there is only one RXD pin on a Raspberry Pi. That's why I'm trying to redirect both signals to the same pin. | |
| Dec 12, 2016 at 11:06 | comment | added | Andrew | Any reason why you can't use two different inputs on the Pi, one fore each signal? | |
