Hello @nebosa check the ADS1115 datasheet (linked here under Related Link). Section I2C Address Selection describes how to change the I2C address. Looking at the board of my AMeter I can see that it is partly prepared to select a different I2C address. One can move a 10 k resistor from one location to another to switch between 0x48 (default) and 0x49. To select 0x4A or 0x4B requires a bit more work, I am afraid. Below picture illustrates my modification to change the AMeter I2C address to 0x4B. Thanks Felix
