Smart Plug 3000W

Hardware

Hi,

Any recommendations about a Smart Plug which can handle 3000 watt (electric heater) ?

May be Zigbee or Wifi… And EU plug.

Thanks !

I’m using - https://www.amazon.de/-/en/switchable-Control-Directly-compatible-Compatible/dp/B077VNL75Z/ref=sr_1_5?keywords=osram+smart+plug+zigbee&qid=1667715929&sprefix=osram+zigbee+p%2Caps%2C129&sr=8-5 and they are very solid. Only problem is that they are missing Power Meter.
Also I have few Neo Coolcam - zWave - they are OK, with Power Metering and there is also WiFi version, but I’m not sure that supports Power Measurment.

(3000w = 13A at 230v, max load in the UK (don’t know about EU plugs))

I would say any of the plugs from well known companies would be safe if they’re rated at 13 amp.
(Obviously not anything generic which might have fake CE badging)

I use the Wifi plugs, TPLink HS100 and HS110, plus the smaller MiniKasa types extensively. I have one that runs a 1kw immersion heater which can be on for several hours in a warm room, and that’s been fine, but nothing that runs at 3kw. I also use the Amazon Zigbee ones which are also fine.

Do you have an example, which can be integrated in home assistant ?

Hi Tsar,

Yep - these. There’s a native integration in HA that supports these devices fully.

Use a Shelly Plug. There is a small version (Plug S) for up to 2.5kW and the bigger Plug for full 16A = 3.5kW.
Shellies have WiFi and can stay local only. (Cloud optional), Full HA support!
There’s no better plugs imho.

Seems indeed the best solution…have already shelly 's in the house, without problems.

Thanks !

I am using few of these and they are also good:

Mostly unkown but the common EU Wall socket (“Schuko”) are only rated/tested for short term 16A (tested only for 1 hour) - the permanent current it is allowed should be 12A (which should be tested for minimum 12h or even 24 hours at the manufacture).

Actually fake or real CE doesn’t matter as it’s not even mend for consumers. Many people put a lot of (fails) hope in this sign which can be legally printed on a product without any certification or testing :warning:

CE marking indicates that a product has been assessed by the manufacturer and deemed to meet EU safety, health and environmental protection requirements.

One of the many 100% useless markings/badges… :bell:

:put_litter_in_its_place:

For power metering the Shelly plug uses (or used?) the “well known” (well inaccurate) HLW8012 sensor. If it’s about accurate readings this device should be avoided - instead maybe something with a CSE7766 or at best a PZEMAC should be used :bulb:
