Dooya 2702 RF Remote #372

Open martin072 opened 3 years ago

martin072 commented 3 years ago

Hi All,

Did any one managed to get the 15 Channel Dooya 2702 RF remote working with this library (https://www.aliexpress.com/i/32917187487.html)? I have the device in house, but it does not seem to work. Some guidance how to sniff the remote would be an option as well so I can try to get the signals?

Many thanks

So I've managed to run the scanner, however, I am a bit stuck with transposing all the values... if there is someone who could help me out.. I looked at the 'Add new remote' section, but a bit confused how to interpret the data.. I've included two samples here:

One: 1076,1426,13207,2188,1072,1062,1057,1073,719,1428,720,1090,1075,1428,1073,1072,718,1077,1074,1090,1074,1074,1076,1071,1428,1070,1071,735,1076,1425,1070,720,1075,1076,1426,732,1074,1076,1426,719,1073,1074,1429,13200,2191,1066,1064,1060,1073,719,1425,721,1088,1076,1427,1070,1073,719,1073,1076,1087,1075,1074,1076,1072,1424,1071,1071,736,1075,1422,1074,718,1073,1073,1426,734,1076,1072,1425,719,1077,1073,1426,13201,2192,1068,1065,1056,1075,717,1426,720,1088,1076,1424,1072,1072,718,1078,1072,1088,1077,1072,1077,1071,1426,1070,1072,734,1077,1422,1075,716,1074,1075,1427,732,1075,1076,1422,720,1073,1076,1427,13200,2189,1070,1059,1064,1074,720,1423,721,1089,1075,1429,1069,1071,720,1075,1076,1087,1077,1072,1076,1074,1425,1072,1069,736,1076,1424,1072,717,1076,1075,1424,734,1077,1073,1426,719,1073,1077,1428,13206,2191,1066,1056,1068,1071,722,1428,718,1089,1075,1428,1071,1071,724,1070,1076,1091,1073,1072,1075,1076,1425,1072,1070,738,1074,1423,1073,721,1073,1075,1424,735,1077,1073,1429,717,1073,1076,1424,13443,2187,1072,1053,1070,1070,721,1426,720,1089,1074,1426,1075,1067,721,1074,1077,1085,1074,1076,1073,1075,1423,1071,1075,731,1074,1425,1071,720,1075,1075,1424,732,1077,1073,1427,716,1075,1077,1422,13057,2188,1071,1071,1050,1076,717,1428,722,1090,1073,1427,1072,1073,719,1077,1074,1090,1075,1074,1074,1075,1426,1071,1071,734,1076,1424,1072,718,1077,1075,1427,732,1076,1073,1427,719,1076,1074,1429,13152,2191,1067,1072,1055,1069,721,1429,721,1087,1075,1425,1073,1074,719,1073,1077,1091,1073,1074,1075,1074,1428,1069,1072,737,1072,1427,1069,721,1078,1075,1425,735,1074,1075,1426,719,1074,1075,1426,13146,2189,1071,1059,1063,1072,720,1426,720,1092,1073,1426,1076,1070,720,1076,1076,1086,1078,1073,1074,1076,1423,1073,1073,733,1074,1424,1073,720,1077,1072,1425,735,1073,1074,1428,719,1076,1075,1425,13149,2191,1068,1067,1055,1073,722,1425,721,1092,1072,1424,1074,1070,722,1075,1074,1090,1076,1073,1076,1074,1427,1072,1069,735,1075,1426,1072,718,1076,1075,1426,733,1075,1077,1426,717,1078,1072,1428,13026,2187,1075,1067,1051,1074,720,1428,721,1091,1072,1428,1071,1074,721,1073,1075,1091,1073,1075,1073,1076,1426,1072,1070,735,1077,1422,1074,718,1076,1075,1425,733,1079,1072,1427,718,1076,1071,1424,13146,2191,1069,1060,1060,1072,722,1428,719,1088,1074,1427,1070,1073,720,1078,1072,1087,1076,1074,1078,1071,1426,1070,1071,735,1077,1426,1071,719,1074,1074,1426,733,1074,1074,1428,719,1075,1073,1426,13154,2184,1072,1064,1057,

Hi Martin, I am struggling at the exact same issue; Just added six remote controlled blind to my home and now I am at the point to control them from a Pi or similar. I am blocked with scanning already... I used a scanner on RPi (https://github.com/omerl13/raspberrypi-rf-dooya-controller) and a series on available and self-written programs on EPS8266, but could not get a consistent picture of the signal send. I will continue with my research and post any outcomes here.

joetriskaide commented 3 years ago

Hi @martin072 I was successful in getting my blinds controlled from an ESP8266. I assumed that the remote I use would be more or less the same as the one you use. Looking at your oszi-image, I can see remarkable differences in the timing of the bits. A look at the first few pulses (1076,1426,13207,2188,1072,1062,1057,1073,719,) unveils a few of them: I assume the big gap of duration 13207µs is the gap between two repetitions of of the signal. A new one starts with 2188, 1072. My timings are different: ~4700/~1600 respectively. Another difference is the relation of the "1"-time vs. "0"-time. Your first data pulse (as I assume) is 2188 on and 1072 off. The pulses I see in my remote are either 350 on/750 off or vice versa, i..e the pulses are about 2:1 in length while yours are about 1:1 in length. Same is true for 1062 on/1057 off) while 1073 on/719 off has another on/of time relation. I wrote an interim sketch for an ESP8266 to understand my Dooya remote and simply replay the timings which came out of https://test.sui.li/oszi/Sketchbook/SimpleRcScanner.ino. You can use the picture at https://test.sui.li/oszi/ to find repeating pulse patterns (in our case it would be good enough of look for timings >10000 for example) and use this very simple sketch to send a copy of block fo the pattern out. (in your example above, I would try the numbers ,13207,2188,1072,1062,1057,1073,719,1428,720,1090,1075,1428,1073,1072,718,1077,1074,1090,1074,1074,1076,1071,1428,1070,1071,735,1076,1425,1070,720,1075,1076,1426,732,1074,1076,1426,719,1073,1074,1429,13200) If you are interested, I will polish my existing sketch a bit and upload it to a repository. Let me know.

martin072 commented 3 years ago

Hi @joetriskaide

Thanks for that. If I have some time this weekend, I will try the sketch.. I just realised the 2 uploads are from the same button, just two recordings as such. I am struggling a bit how to convert this to the protocol definition. The 2702 is a 16 Channel remote maybe that's why it differs so much.

If there is anything I can supply to help, please let me know, I would love to get this thing working on the library (so I can use it with Tasmota)

joetriskaide commented 3 years ago

Hi @martin072 , I managed to get the Dooya 1603 remote (is a 5-channel remote) working in Tasmota. What strikes me is that whatever I read for Dooya-remotes differs from what I see in you received timings. I am even not sure the pattern can be mapped at all to rc-switch. What I understood from rc-switch is that the lib works on the assumption there are 2 pulses: one for a "1", one for a "0" and the pulses are usually a high state followed by a low state. the length of high vs. low state defines whether a "1" is transmitted or a "0", i.e. in my remote there is a "short, 340µs" high state followed by a "long, 680µs" low state defining a "1" to be transmitted Looking at the number you scanned, I can see more than two long/short and short/long patterns: There are patterns where the high state is as long as the low state (1062,1057), follow by a long-short pulse followed by another long-short pulse, where the "high" state is remarkable longer as in the previous pulse. I am new to rc-switch, but to my best knowledge, that is not the way the rc-switch lib works. They assume a fixed pattern for "1" and a fixed pattern for "0", not so much of a change like in your scan. Having said that, there is the notion of triState which I haven't looked at because there wasn't any need for me and somebody with more knowledge on triStates chimes in help you with your remote.
