Power strip with separate power measuring

Hello everybody, does anyone know if there is a power strip (wifi or better zigbee) with separate controls and power measuring?

I am now using some single sockets attached to a classic power strip but I would like to have an “all-in-one” solution.

I found some devices on amazon.it and other european stores, but the power consumption shown is for the whole power strip, not for the single socket :sob:

I hope there are any but I doubt it. The question comes more often so there is a market. But still, for that the manufacturer cannot use the standard power strip internal design but needs to separate the power feed to the sockets. That is more expensive, which makes them a harder sell. A design more similar to classic power strip is simply easier to manufacture.

@Edwin_D

i found this one…

but is Zwave and for US only… :sob:

It is very strange that sonoff and the “other usual suspects” doesn’t produce similar products (with this price range)

Take a look at the Tapo p304m Tapo P304M | Smart Wi-Fi Power Strip | TP-Link United Kingdom which features individual control and power monitoring of each socket

mmm… maybe I am wrong but it seems that this power strip provides a total power usage, not for the single sockets…

I own a p304m. I can see individual power monitoring for each socket in HA

If you’re in the USA, I would recommend going with a power strip for $6 and four of these for $36 … half the price the Zooz.

oh really! that is a great news!
Thanks! I will find the version with EU sockets (like schuko)

@OldSurferDude no, I am in Italy

Make sure the devices will fit next to each other on the power strip. For the USA it will be a very close fit! (maybe not at all :fearful:).

I found a Ledvance Smart+ powerstrip for 10€.
It has power monitoring and power on/off separately on each of the 230V outlets.
The USB share the power monitoring and power on/off.

It can be controlled by the LocalTuya integration.

I will not recommend it though, but that is only because I hate all Tuya.
The product seems okay though.

I found the same on amazon.it (but 3 times the price) but it is not clear if the power meter is on every socket or for the entire power strip

I used some smart plugs (zigbee) from Osram and now Ledadvance (as I understand) but they worked perfectly, are you sure about the Tuya?

The Ledvance Smart+ product have it on each socket except for the USB which is shared among those.

I think I still have the LocalTuya config file.
I can share it once I get back home in a day or two.

Thank you!

I need this for my homelab to power (and monitor) each pc or device connected… do you know if there is some cheap pdu as alternative?

No idea.

I have chosen to go Matter and the selection is still somewhat limited there, but I hang back instead of going into other protocols.

thanks

I will find something on internet… I don’t like tuya

Otherwise I am thinking to build my own powerstrip using:

  • a 1U rack blind panel
  • a din bar
  • a Shelly 4pm
  • 4x din schuko sockets
  • wires and pins

I think that with less 140 euro I build it, and I will have space to add more Shelly 4pm with sockets

The diy solution is surely viable for a local lab where in case of any problem you can switch the power to another source in case of failure.
You may want to buy a spare Shelly just in case.

For unattended situations I suggest the use of a (fairly highly priced) metered and remote controlled PDU.

i am totally agree with you, but since I will use it for my home rack it will not be a problem if for an hour or two the “servers” will been off.

Anyway I already have another shelly 4pm to measure the for “sections” of my studio/homelab and it works without any issues so it is very reliable.
I am use it just to measure the power so I will not worried about sticky relay etc, if something goes wrong I have a thermal breaker for each exit and a differentials before the shelly

If you don’t have high loads, you could even fit two shelly 2pms inside some power strip.

If you remove the internals of the 5th socket and the switch, likely you fit shellies there. At least I managed to fit Esp dev board, 2-ch relay module and some sensors to similar strip…

Most (especially cheaper) power strips use a set of two continuous metal strips going through all outlets (kept in place by plastic prongs), you generally can’t cable them up individually - and cutting the strips/ soldering cables will affect their stability and spring-like behaviour to graps the plugs. It’s quit unlikely to work out, not that most newer power-strips could be opened ‘neatly’ in the first place (glue, plastic clasps, rivets, etc.).

Some older (high-priced) 19" rack power-strips might actually have individual power sockets (and maybe even enough space in the case for esp32 && relais), but identifying those is the real challenge.

I received the Sonoff switches. Two can be put into a standard US outlet but they take up too much space for a power strip. At every other outlet, 3 for a vertical power strip and 2 for a horizontal.
