Yes my bad it is the SBS01V sorry. `send_voltage(VOLTAGE_SLOT,(uint16_t)128, (uint16_t)255);` this send 2 voltages. The only one that i can read is the second one. I dont understand how the...

The rs304b already send internal voltage on slot 0. That's maybe why. I dont think it's a bug, i have the same problem with the exemple included in the library.
