BlitzWolf Inexpensive & Compact EU & US Smart Sockets Work with ESPurna & Sonoff-Tasmota Open Source Firmware

Orange Pi Development Boards

When I first started to look into WiFi smart sockets a few years, there were some fairly compact models such as the Linux based Kankun KK-SP3 or ESP8266 based Konke Mini K sockets.

In recent years, more wireless smart sockets have come to market, but fewer companies have made compact models, and for example Sonoff S26 or Sonoff S31 smart sockets are not exactly small. But this morning I got contacted by a company called BlitzWolf that sells various accessories including low cost and compact smart sockets for the US and EU markets.

BlitzWolf EU / US Smart Sockets

It could prove to be interesting, so let’s check out the specifications:

  • BlitzWolf BW-SHP1 US Smart Socket

    • Rated Voltage – 110-240V @ 50-60 Hz
    • Rated Current – 10A (Max)
    • Max Total Power Output – 2000W
    • Dimensions – 4.5 cm ∅ (VO fireproof material)
    • Temperature Range – -10 to +60°C
  • BlitzWolf BW-SHP2 EU Smart Socket

    • Rated Voltage – 110-240V @ 50-60 Hz
    • Rated Current – 16A (Max)
    • Max Total Power Output – 3840W
    • Dimensions – 7.9 x 6.5 cm (VO fireproof material)
    • Temperature Range – -10 to +60°C

The US version is really small, but the EU version not so much, however the latter also supports power monitoring so you can keep track of the power consumption of the device connected to the socket.

Smart Life AppBoth versions can be controlled via Smart Life app for Android and iOS, which also integrates support for Google Home, Amazon Alexa, and IFTTT.

The product pages do not mention the WiSoC used for the sockets, but it’s pretty clear the device is based on ESP8266 (or ESP8285) since the European version (BW-SHP2) at least is supported by both ESPurna and Sonoff-Tasmota open source firmware. So people who normally prefer have full control over their devices without relying on a third party would be able to upgrade the firmware to use the socket with MQTT, Domoticz, and so on. That would have to be confirmed for the US plug however, since it is not listed.

Blitzwolf BW-SHP1 US smart socket is sold for $10.99 and up on Banggood and Amazon US, while BW-SHP2 EU smart socket can be found for the same price (amazingly) on Banggood, and you’ll find the model on Amazon DE, and Amazon FR. Note the DE and FR models differ, so make sure you buy the right one if purchasing from Banggood.

These devices are really nice. I am currently looking for a EU mechanical wall switch (not touch),that works with tasmota. Anyone found any? Also a dimmer switch, but I know that is not supported yet in tasmota as they usually use stm32 microcontrollers.

Unfortunately the banggood coupon code does not work for the EU plug (not available for limited offer products)
amazon.de price is eur 20.99 (banggood eur 9.43).
I also noticed this one on amazon.de:

https://www.amazon.de/dp/B078YQ73JV/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B078YQ73JV&pf_rd_m=A3JWKAKR8XB7XF&pf_rd_p=5d9f1d21-75bb-4018-838c-214f697868c6&pf_rd_r=H03D5FGB95ZZBZP4XGDW&pd_rd_wg=o3hS3&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&pd_rd_w=Thfvx&pf_rd_i=desktop-dp-sims&pd_rd_r=73b419b0-ac1a-11e8-b0cd-5590e01106d2

Not sure how good that one is and what it can do. 2 for eur 20.

On bangood, it is not compatible with FR plug. It is clearly written at the end of description.
On Amazon FR, it is also the DE wersion that is sold as users comment it in the reviews.

Hi, is there a hole for french type socket? It’s not clear from the images.

Sad that the “EU” plug is compatible only with german plugs and not the one used in France, Belgium, …
Another thing bother me… are those CE certified ? How can they even put a proper relay in those tiny case ? What about tracks isolation for the “main” ?

Color me paranoid but, I’m not very at ease with that sort of thing plugged all day long.
Some weeks ago my electricity provider made an enourmous mistake, replacing my electricity meter, they somewhat managed to put 380V (instead of 220V, 2 phases instead of neutral + 1 phase ) … I can’t imagine what will happen if sometthing like that was actually plugged in.

It looks very well and SHP2 version should be compatible with devices in Romania at least. I was able to find it on AliExpress at around 14 EUR. I placed both in my wishlist there.

You can order from banggood cheaper. I ordered one to Serbia (it is delivered) and it looks like very good product. I think most of continental Europe have this plug (exception being France and Poland).
