The SonOff RF Bridge uses the ESP8285 and not the ESP32. It can be flashed with both ESPHome as well as Tasmota. MIne is flashed with Tasmote. The Chip used for 433MHz communication is EFM8BB1 which I have flashed with Portisch FW. On order to flashe the EFM8BB1, I had to make some HW modification:

Thank you for this. Being a bit noobish I understand better when I can view all the code at once. Would it be possible for you to post all your yaml files somewhere? Regards.
Excluding the standard YAML code, this is what I use for controlling my switches.
And yes, someone could potentially use this information to control my switches and in that case, please go ahead and do that but be fast because they are being replaced with Wi-Fi enabled and Tuya cutter lights and switches in a fast phase 
As you can see I haven’t enabled the receiver and I have turned of the web service because if not, the device will reboot all the time. Maybe it’s only my device or all are the same. I remember i also did the HW mod, but as I remember it was not only these two wires i was cutting it was also a third one if I remember correctly.
As my experience from playing with the ESPHome Dallas component is that the timing (not using timer interrupts) are not that precise I guess this might cause some problems having both the web service and receiver running at the same time as you try to transmit. So if it’s unstable having both the receiver and transmitter running, turn of the one you don’t use for the moment.
Also. It’s not fun to re-flash every time you add some device. I have seen some setup where the codes was provided via the API from HA to the ESPHome device and that setup would be better I think. But I didn’t know enough about ESPHome YAML configurations at the time I configured this but someone else might step in here

any idea why the RM433 remote from Sonoff does not work well with Sonoff bridge?
Hi, I have my Sonoff RFBridge flashed with Tasmota and Portisch. It works well to decode most 433MHz devices I have, except for the Sonoff 433 RM Remote control. In fact the bridge isn’t able to read anything from the remote in rfraw166 mode, but in rfraw177 mode, it spits out lots of inconsistent garbage.
Have you found any method to read, decode and eventually mimic (simulate) RM433 key codes using the RF Bridge as a trnasmitter?
