Successful sniffing but received doesn't respond. Any suggestions? #184

Sonoff RF Bridge flashed with latest Tasmota and Portisch. I'm trying to control a smoke machine which uses (what I assume is) an RF remote. Here's some sample sniffing.

I'm using BitBucket to convert and have been sending the result.

17:20:51 CMD: rfraw AA B0 21 03 08 015E 03A2 2788 A0918090909180918091809180918091809090909181809090 55
17:20:51 RSL: stat/tasmota_EE27B7/RESULT = {"RfRaw":"ON"}
17:20:51 RSL: tele/tasmota_EE27B7/RESULT = {"Time":"2020-12-04T17:20:51","RfRaw":{"Data":"AAA055"}}

But nothing happens. I've tried with every line I've sniffed, but nothing happens. Anyone know what's going on?

Just spent ages with same results as you. no idea whats happening.

Most likely the first 6 segments will be constant (that’s what defines the protocol) so try gathering many more rfraw results and then selecting a combination of the most commonly appearing codes. Eg: 010E appears 3 times in your sample so try building a code with that.

Thank you. I'm going to try again and report back.

Turns out it was an error sitting between my chair and the keyboard.

The remote I was trying to sniff was 315mhz, which the Sonoff RF Bridge does not detect. I'm going to build an ESP8266 ESPHome device to achieve something similar. I guess what I was receiving was just background noise.
