Concurrently here redoing my 1-wire networks such that they utilize Mosquitto.
Old original 1-Wire used Maxim and Midon Temp05's and Temp 08's to autonmous serial connections. It was multiple cat5e wires punched down to a block configured in a star topology. Used direct serial and xAP at the time. Worked fine for many years.
Newer 1-Wire configuration went to using two RPi's running OWFS to Mosquitto via Node Red. Works fine this way. Too much overhead though.
The POE RPi in the attic is multitasking today running ZWave (ser2net), Node Red to Mosquitto, HB 1-Wire lightning sensor and an SDR for NOAA old weather satellite picture downloads.
Newest 1-Wire configuration is more basic and will be utilizing two $4.00 Sonoff's with DS18B20 / DHT22 sensors. One mounted in the basement for basement, outdoor and main floor temperature / humidity sensors. Another one in the attic for attic and 2nd floor sensors. All this now will be using wireless such that it is a combo wired and wireless device. Testing first device and slowly starting to add sensors to it. I mounted one arduino style DS18B20 sensor directly to the Sonoff. Temperature's are way off such that I will not be using these anymore. #3 sensor below is the Arduino style DS18B20 sensor. It is way off and has nothing to do with the surface temperature of the plastic sonoff case.

The basement RPi OWF/Node Red is also a Mosquitto broker. Tested running a Mosquitto broker on the micro travel router inside of the OmniPro panel and it works fine with OpenWRT so may RPi Mosquitto broker over to the OpenWRT microrouter...smaller footprint. That and have a couple of python scripts doing Mosquitto router stats.
