SONOFF RF Bridge R2 value always zero

[nonsintetic]

• Hardware used : Sonoff RF Bridge R2 V1.0
• OpenMQTTGateway version 0.8beta
• RCSwitch version 2.6.2
• RF devices tested: Remote 1 , Door sensor and some others.

I managed to upload the firmware without any issues by following the guide. The device outputs messages to the SRFBtoMQTT topics when I press an RF remote, but the value received on home/OpenMQTTGateway/SRFBtoMQTT is always '0'. There are values being produced on /Raw, /Tsyn, /Thigh and /Tlow but they can't be used for anything. Below is a log of pushing the same button on a remote.

The setup I use and remotes tested all work fine with OpenMQTTGateway on a NodeMCU + STX882 modules. Same exact settings except #define ZgatewaySRFB instead of #define ZgatewayRF.

Hello,

With the working setup could you give us the value you are receiving for the same emitting device shown above ?

Here is the same button being pressed on the working hardware:

Could you post also both results also for the door sensors?

@nonsintetic do you have some news about your issue ?

Hello,

Sorry about the delay, I got caught up with work (meh). Here is the output for all the devices I have around. I hooked up both my diy setup and the bridge and recorded it simultaneously from both: Remote control (aliexpress) :

No problem, if I understand well it is working for 2 cases / 3

I think it may be intermittent. Just after doing the test above the remote started working fine, then I reset the bridge and it seems to be outputting 0 now again. When I tested the first time the door sensor and the alarm were generating 0 as well, now they are working fine. Maybe it's a hardware issue.

After more testing, the bridge seems to be giving me the same code no matter what device I use. The diy seems to be doing fine:

This is strange as you proposed maybe an hardware issue. If ok for you could you close the issue
