salut Arnaud,

to those who read: STS is not a UPS, but a static transfer switch, used to
increase power redundancy:

these devices communicate through the UTalk protocol, so mge-utalk should be

Though I must admit that I've not validated it. But I've demo'ed, at
Solution Linux 2005, NUT communication redundancy, using the same STS + 2
pulsar Evolution (in SHUT mode), and NUT powervalue and MINSUPPLIES in

So, depending on your UPSs and preferences, you have two choices.
If you prefer the embedded UTalk way, feedback is welcomed.
