Oh I see you pasted the “open source” version from Urban Dictionary.

Oxford suggests it originates from the Malay for rich which is “rani” which brings it back to the Cape then.

However they do use it like I know it as lani(e) or larnie instead of larney like Urban Dictionary.

No one seems to know.

Larney
Meaning 'posh', 'classy' or 'dressed up', this word is short for 'Hollander', which in the early twentieth century signified an upper-class person dressed in fashionable European styles and distinct from the local 'yokel' or Afrikaner. The words seem to be connected via the intermediate form 'landie', which is still used in parts of Cape Town and Mozambique.

Collins Dictionary:

larney [South African]

First use: 20th century

Origin: probably from an Indian language

This is a South African slang word, which probably originated somewhere in the South of Johannesburg, that describes something which is expensive, fancy and yuppy.

It can also be used to describe a very rich person living in the more affluent parts of Johannesburg, especially the Northern parts of the city.

Peter: Hey Sipho, where do you work?
Sipho: In the north of Joburg
Peter: Gee with all the larnies, huh?

OR

John: Damn, look at that Rolls-Royce Phantom, what a car!
Piet: Yeah, very larney indeed!

Haha I know that.

This thread is the epitome of larnie

And it doesn’t happen when it switches but rather after a prolonged period of it being on.

Not perhaps something like this?

Or maybe.
When I was testing my generator switch over boxes I did it on one of the circuits without switching the neutral (just had them common) and that tripped the EL when power was "restored" even with the gen off, perhaps a similar thing is happening with your double relay setup( the sonoff and the geyserwise).

Well this is the thing, the Earth leakage still isn’t tripping, only the breaker for the geyser.

And it runs fine for ages so the switching on is fine, it’s just after a prolonged period it seems to die.

Starting to think the Geyserwise itself maybe “detects” the Sonoff through some failsafe state, so maybe I should just see about putting it in front of that.

If it requires splicing wiring I’ll just forget the Sonoff.

Giving it some thought, I'm thinking perhaps the tiny contacts in the relay's are most likely heating up over time with that high amperage through them causing the connection to be less conductive and therefore drawing more energy causing the circuit breaker to trip.

I would not really use such small relays on something as power hungry as a geyser, rather using the control device to run the coil on a contactor which would do the switching.
It would last longer too, those little relays burn out over time and contactors are not that expensive.

I’m starting to think it’s actually when turning off that it trips, because that fits the timeline.

I’m at home tomorrow so will setup the Geyserwise accordingly and then see if that is the case.

If it is, I still have no idea why or how to fix it.

If not I’ll see how it likes shorter periods of staying on, maybe timing one session for the kids baths and another for the parents which happens much later.
 
Anyone seen anything for a wireless float switch? I need to connect my tank up -the pump is about 35m away from the tank... it'd be useful if I could get some sort of wireless setup going, that I could monitor via HA

They are not providing us with the necessary certificates to have the devices approved for import.

It's all good importing for personal use, but once you start importing big shipments then customs starts to sniff around.
