[CBU]BK7231N GEYA GRD9L-W Wifi MCB Controller Din Rail Auto Circuit Breaker Recloser
Wanted to incorporate the following device into my MQTT Network:
https://vi.aliexpress.com/item/1005006309773987.html
Actually I wanted to detach the device and use with a RCB. Detaching was simple as there were two retaining latches at the top and the bottom.
It came with Tuya Firmware V1.0.5
I was able to use cloutclutter to flash with OpenBeken using following profile:
Tuya configuration file looked like this:
Suggested config for OpenBeken was like this:
I really do not understand what the following statement means:
And the Tuya section starts at UNCOMMON POSITION 0
Since the device is a motorized device there are forward and reverse relays:
"rl_on1_pin":"15",
"rl_off1_pin":"17",
After experimenting I figured out that
Bridge FORWARD
Bridge REVERSE
GPIO configuration will make this work.
Then there is this PIN which controls the Automatic/Manual control.
If I set it to ON, then above Forward/Reverse actions work.
"back_vol_pin":"14",
I set PINs 15/17 (Bridge) as Channel 1 and PIN 14 (Relay) as Channel 2
So far so good.
Then there are 3 PINs for a Hall Effect Sensor (guessed from the naming) of pins):
"hall_on_pin":"16",
"hall_off_pin":"22",
"hall_mid_pin":"20",
I configured these as dInput as Channels 4,5,6 and I was able to observe the transitions when the relays are operated.
Switch OFF to ON Transition:
Switch ON to OFF Transition
Then there is LED PIN:
"netled1_pin":"24",
and a Button PIN:
"bt1_pin":"26",
The LED has two colors. When using the Auto position with Tuya App the Green/Red status colors were shown. However I was not able to identify how to obtain the RED LED.
When I moved the arm manually to off position it seems to trigger the RED LED but if I operate the arm using the web GUI, the RED LED does not get litup when in OFF Position.
Still playing with this.
When AUTO/MANUAL SWITCH is moved DOWN (MANUAL) I see the following which confirms that PIN26 is assigned to that switch
There is a SENSING LEVER which engages with a mechanism in the attached breaker to detect the ON/OFF position from the breaker also. However I could not figure out yet on how it is detected.
So I want to put these together in a script to make it work like original setup.
May need some help.
1. Probably I need to match Button 26 with Relay 14. That is the AUTO/MANUAL switch enables/disables the FWD/REVERSE relay operation
2. Figure out how to programmatically turn on RED LED
3. Make use of the HALL EFFECT SENSOR inputs to detect the current state? Suppose there was a manual operation of the switch and when software becomes active how can I detect the actual physical state of the switch?

I found the same product with no position sensor on eBay:

Thanks. In fact I picked up the Bridgexx usage from one of these threads. The Bridge Relay is actually a relay which holds (latches) its position without consuming power hence not dispersing heat. My... [Read more]
