[CB2S/BK7231N/BL0937] Interior, firmware change and AVATTO template N-WOT10-EU-W

📢 Listen (AI):
White AVATTO N-WOT10-EU-W socket with WiFi control on a wooden surface.
AVATTO N-WOT10-EU-W is an electrical socket that offers control via WiFi, additionally performing current, voltage and power measurement.
Here I will present its interior and try to change its firmware to OpenBeken so that it is cloud free and can connect to Home Assistant.

Purchase AVATTO socket N-WOT10-EU-.W I received several pieces of this socket from a reader to upload his OBK, but normally this gadget costs £68:
AVATTO N-WOT10-EU-W electrical socket and its price on a website.
Short specification, dimensions:
Technical specifications of the AVATTO N-WOT10-EU-W electric socket. Let's see what we get after ordering:
AVATTO N-WOT10-EU-W socket packaging with importer label. AVATTO Smart Home product box on a wooden surface. AVATTO N-WOT10-EU-W socket packaging with manufacturer label. Full designation: N-WOT10-EU-W:

Content:

There is a manual in Polish:
Polish language leaflet with instructions for the AVATTO N-WOT10-EU-W socket. User manual for Avatto smart wall socket.
The whole set:
AVATTO N-WOT10-EU-W socket set with instructions
English language instructions:
English instruction manual for a smart electrical socket. AVATTO N-WOT10-EU-W socket user manual
Well, and the socket itself:
AVATTO N-WOT10-EU-W electrical socket with WiFi and measurement features. AVATTO N-WOT10-EU-W socket with energy measurement capability

Interior and firmware change I thought, that I would again be analysing a new PCB version and creating a new GPIO template, but not this time.
This socket is practically identical to the Kraslaw piece already discussed:
[BK7231N/CB2S] Socket with energy measurement SWP86-01OG For sure, vendors simply order the same products in China and then put their logo on them.
Thus, I will simply just post pictures from the inside here:

All as in SWP86-.01OG.

In order to change the firmware I soldered out CB2S:

I liked this mechanism for connecting the earth, there is a small pin on a spring that presses against the plate:

Other than that - all unchanged.

What next with such a socket? This topic in a way got very short, because I ended up with 1:1 of the same product as I discussed earlier, so it might be worth quoting a bit more other information that might help someone. So what can be done afterwards with such a socket?
Can be paired with Home Assistant:



Can be grouped with other devices (also Tasmota) without HA:



Can be controlled from a simple mobile app on our LAN:



You can script the device to turn itself on or off at given times:
OpenBeken scripts - Time and schedule using NTP and addClockEvent And much more - it's worth seeing for examples of OBK scripts:

Summary
This time I didn't gain much new information. This device has a PCB compatible with the SWP86-01OG. Nevertheless, I put a copy of the original batch here:

Code: JSON
Log in, to see the code

Template should be added according to the video:




The rest of the comments rather like the previous review - it's not so bad, in this type of product a varistor is a luxury.
