Here is a teardown submited by OpenBeken user, who didn't yet register on Elektroda. I am posting it here per his request.

Hi! I've just finished to make a smart water valve to work with your OpenBeker firmware; (...) I'd like to share what I achieved.
I'd like to share that valve model first: https://www.amazon.it/dp/B092ZRNJK3?psc=1&ref=ppx_yo2ov_dt_b_product_details

You can also buy whole set for this device:

which I believe is a newer revision or rebrand of this tasmotable one here: https://templates.blakadder.com/steren_SHOME-150.html

the basic difference is the newer one comes with a WB3S chip instead.
whit that said, here below my tested and working configuration I've grabbed from the related web-app:

I just flashed a similar device so I thought I'd add my config here.

I purchased it here: https://www.amazon.ca/gp/product/B08GG7H5CP

Here's the template:

~~I haven't determined how to add it to HA yet, but I believe I need an entry in mqtt in my configuration.yaml~~

I just watched this video which explains how to get HA to discover it.

Hello, can you also share Tuya config partition?
See how to get it here: https://www.youtube.com/watch?v=WunlqIMAdgw&ab_channel=Elektrodacom

Regarding HA, it should be possible to use our automatic HASS discovery for that, but it may not specify a custom icon for you, so if you want some special handling for the valve device then you can indeed write your own YAML.
HASS Automatic Discovery guide: https://www.youtube.com/watch?v=pkcspey25V4&ab_channel=Elektrodacom

EDIT: I see you've found the video yourself while I was writing the post, nice. Let us know if it works for you.

Added after 16 [minutes]:

After running that converter, I applied a new config. I also set the startup value of Channel 1 to the value -1 so that it wouldn't close the valve upon reboot or power cycle, here's the current config:

{
  "vendor": "Tuya",
  "bDetailed": "0",
  "name": "Full Device Name Here",
  "model": "enter short model name here",
  "chip": "BK7231T",
  "board": "TODO",
  "flags": "1024",
  "keywords": [
    "TODO",
    "TODO",
    "TODO"
  ],
  "pins": {
    "1": "WifiLED_n;0",
    "6": "Rel;1",
    "9": "LED;1",
    "24": "Btn;1"
  },
  "command": "",
  "image": "https://obrazki.elektroda.pl/YOUR_IMAGE.jpg",
  "wiki": "https://www.elektroda.com/rtvforum/topic_YOUR_TOPIC.html"
}

The only change is the value of pin 1.

Even after setting the startup value mentioned above, the motor still activates momentarily, but at least it doesn't close the valve now.

Thanks, your template should be now live at:
https://openbekeniot.github.io/webapp/devicesList.html

Regarding Tuya JSON - I wanted to verify that all required settings are imported and it seems that they are. For example, here's how Tuya defines Relay pin:
Code: text Expand Select all Copy to clipboard
"rl1_pin":"6",

Thanks to this users can get GPIO settings without guessing/investigating PCB.

I've noticed that whenever we have a power outage, once the power comes back on, this valve closes. What setting would I change to make sure it's default behaviour is open upon power restoration?

Assuming that you just want to retain the value of the channel between reboots, then you just need to go to "Configure startup" and enter a -1 value for a given relay channel.

Topic summary

A user shared a teardown of a smart water valve compatible with OpenBeken firmware, specifically the Steren Valvula (SHOME-150) model. They provided links to the valve and a newer version with a WB3S chip. Another participant contributed a configuration template for a similar device (model SM-AW713, chip BK7231T) and discussed integration with Home Assistant (HA) using MQTT. The conversation included requests for Tuya configuration details and solutions for retaining relay states after power outages, suggesting a setting adjustment to ensure the valve defaults to open upon power restoration.
Summary generated by the language model.
