Tuya ESP D1 mini motor valve

https://www.aliexpress.com/item/32977505873.html…

Soo i buy motor valve.On tasmota site was this valve from Hoenyzy,sad that have ESP chip that you can flash with tasmota.After i open i see thay i have non ESP chip,it was Tuya CBU chip beken 7231N. I want to flash with opnbeken flasher.

The flasher/windows just ding ding ding ding, and cant recognise COM port connected USB+Tuya chip.I reset,…🤬🫡🫡🤬🤯😶😶 no luck. So F. that and replace with ESP D1 Mini.

First: Heat with hot air the chip. Because i dont have hot air: a lot of flux solder and praying and some force peel of the chip.

I broke some traces. So just scrape some color from trace and solder wires to d1 mini.

Flash D1 mini with tasmota,use basic template,and sonoff basic module type.

Use GPIO12 button, GPIO13 led_i, GPIO14 Relay.

D5 relay, D6 button, D7 led.

Use some epoxy glue on wires,to hold that the traces dont tear off the board. Tape the mini on board and you have tasmota motor valve.


Glad to see that you haven’t bricked your valve.
But for anyone who has a similar project, you can flash Tasmota/ESPHome to the new chip that Tuya is using:
