Or use an utility that can connect to miners and show their status and also allows you to send them updated pools settings, this way you can apply new settings for all rigs at once.
That was also my thought, so I do some research.
Unfortunately, it looks like, there is no utility which is compatible with your miner software....

Yes, I think I will have to write it my self, the only problem is that I need to study stratum code and see it works first, a DevOps practice would be to look if the tool exist then just use it and work on improving it.
