I received two replacement Quad SSR’s after it was determined that they (probably) had bad firmware.

However when running i2cdetect on my Raspberry Pi 4 it doesn’t detect either of the two replacement relays. When I connect to an Adafruit PCT2075 temperature sensor and run i2cdetect than it is immediately detected at adress 0x37 as it should.

Apperently I configured my RPi correctly and the connection between my RPi and I2C component is correctly.

Probably still bad firmware??

Maybe; how long are the i2c wires? Can you share a photo of the setup?
