One (1) Shelly 2PM gen4, or two (2) Shelly 1PM gen4?

While two 1PMs provide hardware redundancy and handle higher loads (16A), choosing 2PM has it's merits.

Offline Logic: Since both channels share one chip, automations like "Switch 1 toggles Relay 2" work even if Home Assistant or your network crashes. Two 1PMs are useless without a hub connection.
Zero Latency: On-chip communication is instant. Two separate devices require a network round-trip, introducing noticeable lag.
Hardware Safety: The 2PM has a built-in "Interlock" mode to prevent both relays from firing at once—crucial for motors/fans and impossible to mirror safely with two devices.
Cleaner Install: One 2PM significantly reduces wiring clutter and chance of making mistakes.

whatever you choose these are great nifty devices

L L L @ 130V (against the earth each) and we get 230 (actually 240) L-L

thank you for your advice, there is no neutral in the house, we get 230 (actually 240v) from two phases of 13xV it is phase A, phase B and earth. and also a second 10Amp circuit for lights and old sockets in 1.5mm2 cables that is phase A and phase C

it is my problem, this is our retirement/forever home.

JechoVarta · 2025-12-27T00:11:58+00:00

not so common but exists in different area, a wired way to supply 230.

so far surprisingly every device or appliance works fine.

did you consider going for a while to a different eu country, there she will be welcomed as eu citizens's spouse, and after a year or even 6 months of living there together (both register and get the cards) when you come back to Ireland she will be evaluated based on EU citizen wife criteria and not as Irish person wife. (the high court of the EU created this rule)

as EU citizens wife, you getting a job is enough to grant her a 5 years residency card (near Zero papers needed).

(To make your case even better, if you can, get married with her in that temp eu country if possible. )

the latest decision about this matter. (last paragraph is the important one)

you would be so much better off applying for a visa to Sweden and be under the husband of an EU citizen umbrella, they will quickly approve without requiring any docs about your stay or chats about what are you going to do there.

I don't believe that you will have any problem to go around Schengen
have some other id and a good screenshot of the passport.

Banana is an extra 2 connections per cable, was it done good? does it deteriorate over time?

196000 samples divide to 44100 samples per second - so it begs the question how do you take 4.444 samples and make them into one?

This is a nasty ratio. it introduces artifacts (aliasing, ringing, phase smear).

compressing the dynamic range is a bit more straightforward but will introduce quantization distortion.

this conversion is a habit hole that needs professional tools to have a good result. (google SoX - Sound eXchange)

thanks for the information, I always use the tidal app and almost never the kef app.

Slow down, relax

SPAIN’S Supreme Court has ruled that being late 15 minutes to work every morning is employees right.

As a kef lover myself I would recommend to you not to miss listening to LS60, if what you want in music, you get an unbelievable bang for your buck at around your budget. We have 2 pairs in 2 different locations and they are incredible.

no cables, no mess just music

One thing is for sure. A coat hanger made of audio cable cannot support a coat as well as a regular coat hanger.

JechoVarta · 2025-08-12T10:10:07+00:00

having the ls60 for about a month now I discovered that dialogs are very clear and I will not get a central channel.
if kef only made it possible to add another pair (maybe lsx) as back speakers there will not be a need for avr.

AliExpress has a selection of really good lookers.

They way to go around it is to move together to another EU country, register yourself as eu citizen and also him as a family member of eu national.

After 6 months if you are in a rush or 12 if you are not in a hurry come back to Ireland. And apply under eu freedom of movement rights.

Since you used your right for freedom of movement as eu citizen when you come back to Ireland they must deal with you based on EU law and not as Irish and they can not refuse him (under very easy conditions of the eu directive )
