The new Sonoff DualR3

Hi guys. Quick question. I’ve been looking for a way to flash ESPhome on this device without soldering any wire, is it possible? Already read the article posted before and they say there is no OTA flashing, but that article is from a year ago, so maybe an update could add this feature. Do I have to do the soldering? Thanks!!

Masterzz · March 14, 2023, 11:49am

Check this one: OTA flashing of virgin Itead Sonoff devices

bkbartk · March 14, 2023, 3:03pm

I use alligator clips for this one.

judasepa · March 14, 2023, 11:06pm

Ohh this sounds easy, gonna try it, thanks!

skull29 · March 30, 2023, 3:32pm

Anyone successfully also using it as a BT Proxy on top of all the functions? Thanks.

skull29 · April 24, 2023, 5:20pm

Just wanted to update that I have it successfully working as a BT Proxy as well.

Hi everyone! I’m trying to upload a simple ESPHome config to my new sonoff dual r3 v2.0 but less than 1 sec after the boot it starts to reset continuously.
The config is as simple as it can be:

esphome:
  name: dual-r3-test
  platform: ESP32 
  board: esp32dev

And here is the log:

The dual r3 is powered by a pc power supply… so I don’t think it’s a power issue. Any idea what the problem could be?

dksl · May 25, 2023, 9:58pm

And of course in the end the problem was the power supply… I tried 3 before before writing here… the fourth was the good one!!

v01t · June 24, 2023, 1:35pm

Just an info for others who will try to use aligator clips, they works but…
my aligator clips were too strong for the board, first flash went successfully, but I did one mistake,
and when I tried to reconnect alligators, circuit were shorted as aligators “teeths” uncover some contacts (scratched), like SW1, so just take into account that you need “gentle” mini alligators for that

bzumik1 · August 24, 2023, 2:44pm

Really cool!

alessocci · August 25, 2023, 8:46am

Hi, I use my DUALR3s to control the window rolling shutters. On some I have wifi disconnection issues that piss me off. I would like to convert them with ESPHome.
I ask you:

I keep all the same functions on Home Assistant?
Can I choose at which level to raise the rolling shutter?
Does the management of the interlocked buttons work?

Thanks to all

MartenFB · September 9, 2023, 11:34pm

Hi, I’m using Sonoff Dual R3 in Home Assistant(2023-09). I have flashed the device with Tasmota and it works so far fine. All Entities are reported by Sonoff Dual R3 via MQTT to Home Assistant.

If I look up all entities in HA Home Assistent, there is no Temperature reported.

Does anyone know, how to get the Temperature-Entity, which is reported byTasmota beside the Voltage, Power, Current etc. on the screen in my browser. This Temperature I would like to have in HA as an entity. Does anyone know whether that is possible?
.

Bl00d-B0b · October 16, 2023, 3:19pm

Tasmota offers to use the zero crossing detection on GPIO4 built into the energy monitoring chip to switch the relay on zero crossing.

This allows for safer and more reliable relay operation. Is this something that ESPHome came do? I couldn’t find anything about it.

bzumik1 · February 2, 2024, 4:43pm

Hi, could someone help me, I am trying to flash about 20 Sonoff Dual R3s but when ever I flash it it ends up in boot loop. It returns this:

I am getting little bit desperate, I have tried everything, web flasher, esphome CLI, different USB to TTL convertors, but still the same

This is thrown by web flasher.

bzumik1 · February 2, 2024, 4:44pm

I have very similar if not exactly the same issue. Have you been able to solve that?

beaj · February 2, 2024, 6:21pm

Make sure you have mains power connected to the Dual R3. As I recall you can flash the device powered from the usb serial connection but it won’t boot.

Edit: Probably want to disconnect serial connection before attaching mains power.

bzumik1 · February 2, 2024, 9:50pm

Thanks a lot for answer! So flashing should work just by using USB to TTL and then I should connect it to main power (220V) and it should boot?

I have already tried that yesterday , but let me double check it.

beaj · February 2, 2024, 10:41pm

I programmed one of these with esphome last year and I remember I had the boot loop problem.

After some searching I recall coming across a post that mentioned the Dual R3 needs more power than can be supplied from the USB TTL adapter. Wiring it up to the mains resolved the issue for me.

They are a pain to connect up so if you have 20 to do I wish you good luck.

bzumik1 · February 3, 2024, 6:54am

Actually with the alligator clips it is pretty easy, one would take me 2-3 mins if there would not be the boot loop issue

I will connect it to main power later today and let you know if it helped. I really hope it will work, I have already spent two days on that.
