You create multiple groups and assign a processing quota. So you can mine the groups at different rates

Just got my asic miner this week and played a little with both options.

What I liked about hive:
great interface
individual chip display, really cool
web control interface, allowing you to manage all your miners centrally (you can even upgrade and downgrade the firmware from there)
fast tuning
better monitoring data (can display stats for more than a day)
provides more extensive data
ssh blocked by default


What I liked about braiins
simpler interface
better tuning (got about 3-4% faster hashrates), but took ages
pool fees are refunded (not sure how this works)
boards runs at lower voltages (0.2V lower)
seems the fans work better
allows you to mine to several pools simultaneously
tries to reduce power to the miner when the temperature rises (Dynamic Power Scaling)
openwrt backend (though it is pretty old v17), just hope they keep the components upgraded
think this is build is not based on bitmain
