...ave the following issue with a Powercom 1000VA ups. Details as follows: Model: Powercom 1000VA (does not mention WOW, Black Night or anything else) Driver: usbhid-ups Nut: 2.6.1 USB Product/Vendor: 0x0d9f/0x0004 The UPS detects power failures, and power back perfectly. The problem is killing the invertor. When issuing the "upsdrvctl shutdown" command, the following happens: - The beep changes from normal "power fail beep" to a shorter "double beep". - UPS will then turn off after a very "random" time, sometimes a minute, I've also left it for...

Hi! I was wonering if there is a driver that supports communicating with a Modbus aware device over IP. I have a solar/wind invertor that can broadcast its state and I would like to monitor the batteries. If they discarge to a certain voltage or come to a defined state, I would perform a shutdown. All of this information id provided in Modbus holding registers. This could of course be done placing a Modbus-to-SNMP gateway but th...

Yeah, I have its datasheet (it's a Xantrex XW invertor by the way). I do not know why creating a more-or-less generic driver is an issue. Of course, there are Modbus beasts that can scare everyone but mostly one would need to read either intreger or float numbers out of Modbus registers in order to decide whether or not to start or stop the shutdown pr...

...does exactly what we need. Now we are starting new era, with installing telescopes on hostile spots without infrastructure. So we will have a solar cells, storing power to batteries during day, to be used during night to run the observatory. We bought Victron Energy solar system, including theirs invertor and battery monitor. Victron has its own tools, but the serial protocol is well documented and quite easy to understand. I would like to add NUT driver. But I will need to add new variables, showing state of different solar panels, connected to the controller. Can you suggest where to put those?...

Dear Fellow *-ers, First, you guys are fantastic. Keep fighting the good fight. Second, it sounds like comments in the code are coming, which sounds welcome by all, even those of us who couldn't code their way out of a papersack, but who need to read the source. Last, I might be traveling to Europe (from US) & want to tow along hardware & haven't done this before & was
