[CB2S/BL0937] No name plug (QNCX) 20A (actually 16A relay)
Plug purchased on ali in the promotion "3 items from" for 2.99 USD as 20A with energy measurement. The box is completely noname, there are also no inscriptions on the plug.
Plus there are two diodes - blue for wifi, red for on / off.
Link without promotion: link
Initially I was going to use it with domoticz with Tuya plugin but curiosity prevailed.
Attempts to upload via tuya cloudcutter failed.
Demolition - practically damage-free with such a clamp:
Now I know that such sockets can be dismantled without much problem, only a moment of patience is required, i.e. 2-3 minutes
Inside there is a surprise: a 16A relay, the thickness of the solder and the PE cable is not great.
I opened a dispute on ali and they gave back half the price without resistance.
There we find the CB2S chip and the energy measurement using BL0937
I desoldered the CB2S for programming, the braid is necessary.
Soft uploaded using BK7231 GUI Flash Tool - here I had a small problem at the beginning because WIN10 lost the drivers for CP2102 after the next update, but after realizing the situation it went without major problems.
Configuration with the help of other topics from the electrode:
P6 BL0937CF1
P7 BL0937CF
P8 LED (blue)
P10 Btn
P24 BL0937SEL
P26 Rel (probably also a second red diode here)
After calibrating with a 60W bulb that is actually 62W at 229V and a Fluke multimeter it seems to measure approx.
Only with the OFF position there is a strange measurement instead of 0.
edit: Flag 38 helped with off measurement
If there was such a plugin, please remove it, this is the third device on which I uploaded openbeken, previously two mini switches - one OTA, the other soldering.
Thanks to the creator - respect!
