Hello. I have this socket It works even well, but it has one minus. It doesn't cut off the minus when you click OFF. It only cuts off the plus. Does anyone have a proven smart socket or strip that cuts everything off when you click off? .

Hym, I don't know if you'll find such a small one with a relay that disconnects phase and zero because there's not enough room in these sockets for something like that.

Is it possibly a skirting board?

Elements (switches, connectors) that cut off the power on all poles simultaneously are commonly called mains switches . Maybe if you type such a phrase into a search engine you will find what you are interested in. And just out of curiosity. Why do you need such a socket? Perhaps if you write why, others will recommend other solutions.

I have a Green Cell 2000VA 1200W UPS connected. When I switch it off with the button on the front it still pulls 30 / 40 watts. So it wants to switch it off at least from 1am to 9am. It's a bit strange that the UPS button on the front doesn't cut the battery power and shut down the circuit to zero.... Well, but as you can see GC didn't show off ;]

In the mains, i.e. also in the sockets, we don't have a minus . If you unplug it overnight, it will still draw that power as soon as you switch it back on. It is simply that the UPS electronics follow a set algorithm to keep the battery in good condition. Every device of this type has a certain efficiency (for an economy class UPS it is no more than 93%!) and a certain level of energy self-consumption (e.g. to power displays, LEDs or standby electronics). Losses are therefore unavoidable by any means, and buffering in batteries usually takes up a total of around 20 per cent of the energy stored in this way. You simply have to pay more for your electricity for the added security. And such losses due to the UPS design simply have to be factored into the cost of powering the equipment.

Hi, I would like to reheat the topic, I am also looking for such a socket or strip. The socket would cut off an emergency UPS with a 100ah battery to simulate a lack of mains power.... I have a similar socket to the one in the first post, but after switching it off, the UPS continues to see some power fluctuation and cannot switch fully to the battery.

I am looking for a smart socket or strip that cuts off both poles when switched off

Hello.
I have this socket https://allegro.pl/oferta/inteligentne-smart-...o-wifi-watomierz-programator-tuya-12619206396

It works even well, but it has one minus.
It doesn't cut off the minus when you click OFF.
It only cuts off the plus.
Does anyone have a proven smart socket or strip that cuts everything off when you click off?

Topic summary

The discussion centers on finding a smart socket or power strip capable of disconnecting both live (phase) and neutral (zero) conductors simultaneously when switched off. The original device linked is a WiFi-controlled smart socket with power metering (Tuya-based), which only interrupts the live wire, leaving the neutral connected. This limitation is problematic for users with UPS systems, such as the Green Cell 2000VA 1200W UPS, which continue to draw standby power even when switched off, due to the UPS design and battery maintenance algorithms. Respondents note that typical smart sockets lack the physical space and relay configuration to cut both poles, as such functionality is usually found in dedicated mains switches. The need to fully isolate power to simulate mains failure or reduce standby consumption is highlighted, but no specific smart socket or strip model with dual-pole cutoff is identified. The discussion also clarifies that in AC mains wiring, the term "minus" is inaccurate; the neutral conductor is referenced instead.
