DS2482-800 is an I2C to 8x one wire port converter
We like our breakout for the DS2484 (https://www.adafruit.com/product/5976), an I2C to one-wire converter – and got a heads up that there’s also an 8-port version called the DS2482-800 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/DS2482S-800/1197437). at first this seems a bit odd: the whole point of one-wire is that you can share that wire with all sensors. But you don’t want to have to deal with the DS18b20 sensor addressing to determine what zone it’s in that would require hard-coding the unique identifiers. This way, you can have up to 8 temperature sensors that can be hot-swapped.
