My Fibaro network is running fine... at 115 Volt

[petergebruers 1,268]

It's not a typo in the title... By accident 2/3 of my home is running at 130 Volt.

Some explanation. I'm connected to the grid in a somewhat unusual way. I have three phases named L1, L2 and L3. There is no Neutral. So a pair of L gives 230 Volt. If I had a neutral (which i don't have) L to N would show 130 Volt.

What happened is, L2 dropped out. That means one third of the house has 230V and the other two form a voltage divider, giving the other two thirds roughly 115 Volt.

My Fibaro Wall Plugs, Relays and Dimmers just keep working in this configuration. Of course, a halogen lamp produces only a faint glow. Some LED start but not all and my old fluorescent don't ignite at all.

Maybe not important... But quite fun! Very much so, when my motion sensor switches on the halogen in the hall. The faint glow is very spooky

The wall modules are able to run on 110 to 230 ac or 24 to 60 dc so as designed for relays. I guess not surprising power socket can manage the same.

Most modern electronics is actually designed for this - LED lights might not be, because their power supplies are made to be as small as possible. It is cheaper and easier than to make both a US and most-of-the-world version.

 

I'm still not quite sure I understand why you would have a 3-phase 230 V system in Europe though - even though you have mentioned it before. It seems strange and I would expect that you see some strange interference issues because you don't have a common neutral
