Moes ufo-r2-rf with WR3E

[iMatux]

Hello! Yesterday I received this IR/RF blaster from Aliexpress, I though it had an ESP chip like ufo-r1 version, but after teardown I saw that it has a WR3E chip, which seems not compatible with Tasmota, as it has a RTL chip inside, like Tuya Developer site says. This is a really great product has it has IR and 315/433 mhz for RF and it's really cheap. If anyone needs pics here they are, including wiring prototype from a doc on Tuya site linked before:

A year after I tried again, bought a Esp8266 12S, soldered without pulling any pin, flashed Tasmota and it work, now I have to figure it out how to set GPIO and template in Tasmota and it should work, hopefully.

Hi, very interesting - LED wise the interior looks very much like my YTF IR bridge (https://tasmota.github.io/docs/devices/YTF-IR-Bridge/) which still came with ESP8266 and that I´m using as IR blaster. Due to the several LED it has a great reach - even gets "around corners", obviously reflecting at walls ...

Looking at the HW this one seems to have 3 antennas for sending - so I would guess it should have a good reach for RF too ...

I found yours on AliExpress for about 20€, which is not too bad in pricing.

I´d be interested if you find the GPIO layout (guess it should not be too hard finding it by guess and try ...

Please share your experience - thanks - MacSass

Hello,

Could you elaborate a bit how you open the case of this device? Been pulling it from the side but it feels like it would damage the plastic... Thanks !

@yvesdm3000 I've just opened one and confirm there are no external screws.

You just need to use one of the tipical smartphone repair tools to pen it thorugh the middle. You have two tabs on each side close to the corner.

[gonzzovela]

has anyone figured out the pins used by the board? I'd like to use it by replacing the WR3E by an ESP.

Thanks,

How did you open it ?

[yvesdm3000]

I pried it open with a plastic tool used to open a smartphone / tablet.

LibreTuya-ESPHome is working fine on this RTL8710-based module, fwiw. But I would love to find a way to do the initial installation OTA if possible, rather than attaching wires to the module pins.

@RoganDawes I'd love a bit more info on how you did it. I ended up with some RTL circuit breakers on advise from my electrician and decided I'd figure out how to integrate them later. Dumb idea.

[RoganDawes]

I'm guessing you have the CBI Astute smart controllers. The only way that I know of to flash them is to open them up, and connect wires to the appropriate pins as per the libretiny project. If you have access to a 3D printer, there are some models that can put pogo pins in the right places to save soldering, although I have not had the best results that way!

Details can be found here: http://docs.libretiny.eu/docs/platform/realtek-ambz/

Use ltchiptool once you have created a suitable config file (basically, the bare minimum, including the ota: and wifi: details.) Even with nothing wired up, ltchiptool will try to connect to it, and when it times out, will print out the wiring required. You'll also want to find the WR3E pinout to get the corresponding pins on the board/module.

[ChrisGroenewald]

You guessed correctly. I'm no stranger to the soldering iron, so it's not a problem. I'm considering picking up a spare one and playing with that first to get the process down pat. Awesome info, thank you! I'm looking forward to getting them out of the walled garden.

Good luck. Shout if you need help with the yaml configuration.

This is what I had prior to the change where libretiny needs to be updated to the cpu platform (rtl87xx:). I no longer have any of these devices, so have not bothered to update it. It is strongly recommended to include the web_server: and captive_portal: components in all firmware uploaded to these devices, in case you enter the wifi credentials incorrectly!). If you are having trouble getting current and power readings from the device, try adding the inverted: option to the CF and CF1 pins.

Thanks for your contribution Rogan, but i think you uploaded code for wrong device. The Moes ufo-r2-rf isn't power metering switch, it is an IR/RF remote.

Sorry, I thought you were responding to my post in e.g. https://github.com/ct-Open-Source/tuya-convert/issues/901#issuecomment-1719122345, where I was talking about the CBI Astute Smart devices, which are also based on the WR3E module.

Unfortunately, I do not have the Moes ufo-r2-rf, so have no idea what sort of configuration would be required.
