Digoo DG-HOSA Smart 433MHz Wireless Household Carbon Monoxide Sensor

[spider7611]

Have a new CO sensor and the Rf Bridge not received code when I push the test buttons.

Only show this if I use the Rfraw 177:

20:16:47 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 023A 0604 0186 3494 3818181819090909081819090819081908181818181819090A 55"}} 20:16:48 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 0258 05E6 01AE 348A 3818181819090909081819090819081908181818181819090A 55"}} 20:16:49 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 03 024E 05DC 348A 28181818190909090818190908190819081818181818190908 55"}} 20:16:49 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 0258 05DC 01AE 348A 3818181819090909081819090819081908181818181819090A 55"}}

Please try the new branch https://github.com/Portisch/RF-Bridge-EFM8BB1/tree/DG-HOSA with command 0xA6!

Hi, I upload the new hex. Now not received any signal in normal mode. When I type this: rfraw AAA655 then the old remote control show codes like this: 17:28:34 CMD: Rfraw AAA655 17:28:34 MQT: stat/sonoff_rf/RESULT = {"RfRaw":"ON"} 17:28:34 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA055"}} 17:33:35 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA6040034334355"}} But from the CO sensor not received anything.

I pushed the branch again. Please try the new hey file:

Use it with rfraw aaa655!

[spider7611]

I tryed it. In normal mode now working again. But after rfraw aaa655 not receiving any code from the CO sensor.

[spider7611]

Only RfRaw 177 show this:

12:01:00 MQT: stat/sonoff_rf/RESULT = {"RfRaw":"ON"} 12:01:00 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA055"}} 12:01:09 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 0230 060E 0190 348A 3818181819090909081819090819081908181818181819090A 55"}} 12:01:22 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 03 0212 0622 3494 28181818190909090818190908190819081818181818190908 55"}} 12:01:23 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 024E 05E6 01A4 3480 3818181819090909081819090819081908181818181819090A 55"}} 12:01:23 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 03 0244 05F0 3480 28181818190909090818190908190819081818181818190908 55"}} 12:01:23 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 024E 05E6 01AE 3480 3818181819090909081819090819081908181818181819090A 55"}} 12:01:24 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 024E 05F0 01A4 3480 3818181819090909081819090819081908181818181819090A 55"}} 12:01:35 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 0226 060E 0190 3494 3818181819090909081819090819081908181818181819090A 55"}} 12:01:36 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 024E 05E6 01A4 348A 3818181819090909081819090819081908181818181819090A 55"}} 12:01:37 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AA B1 04 024E 05E6 01A4 348A 3818181819090909081819090819081908181818181819090A 55"}}

I think it was because of the "small" snyc pulse of 430µs. Please try this again: https://github.com/Portisch/RF-Bridge-EFM8BB1/blob/7a5b0349c2dc49d813d6c99a6820e53bc9f35fee/Keil%208051%20v9.53%20-%20Release/RF-Bridge-EFM8BB1.hex

[spider7611]

Now what I recognized. In normal mode when I press about 4-5 times the test button it give one code: 12:15:49 CMD: Rfraw 0 12:15:49 MQT: stat/sonoff_rf/RESULT = {"RfRaw":"OFF"} 12:16:06 MQT: tele/sonoff_rf/RESULT = {"RfReceived":{"Sync":13510,"Low":540,"High":1570,"Data":"0F3503","RfKey":"None"}} 12:16:33 MQT: tele/sonoff_rf/RESULT = {"RfReceived":{"Sync":13490,"Low":530,"High":1580,"Data":"0F3503","RfKey":"None"}} so this 2 code receive after about 10 push.

[Portisch]

This is maybe a tolerance issue. For 0xA4 it should be this timing: Sync long: 13440µs Sync short: 13440µs / 31 == 433µs

Bit 0/1 short pulse: 433µs Bit 0/1 long pulse: 1299µs

You have: Sync long: 13440µs Sync short: 13440µs / 31 == 433µs

Bit 0/1 short pulse: 590µs Bit 0/1 long pulse: 1510µs

Now the new hex with RfRaw aaa655 receive codes:

12:25:07 CMD: Rfraw AAA655 12:25:07 MQT: stat/sonoff_rf/RESULT = {"RfRaw":"ON"} 12:25:07 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA055"}} 12:25:21 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA604090F350355"}} 12:25:26 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA604090F350355"}} 12:25:32 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA604090F350355"}} 12:25:32 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA604090F350355"}} 12:25:33 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA604090F350355"}} 12:25:34 MQT: tele/sonoff_rf/RESULT = {"RfRaw":{"Data":"AAA604090F350355"}}

[spider7611]

And what now? In normal mode not receive any code from the CO sensor. How will working for me? :)

[Portisch]

Wrong place. Go to https://github.com/arendst/Sonoff-Tasmota

[spider7611]

Sorry but don't understand why must go there? I hoped will work if I upload the new modified hex. Or must do any modification too?

[Portisch]

You have the sniffed 0xA6 RF data and can do what you want with this data on your host. This repo is only about the sniffing - not the decoding or something else.

[spider7611]

Oh ok. Thank Your help! I just want a code from the CO sensor in normal mode when the sensor send an alarm. But I don't know what can I do with this sniffed data, how to put in the Sonoff Rf Bridge to receive it and recognized it?!

[spider7611]

Sorry again, but in normal mode not received always this code: 12:16:33 MQT: tele/sonoff_rf/RESULT = {"RfReceived":{"Sync":13490,"Low":530,"High":1580,"Data":"0F3503","RfKey":"None"}} But I want when I push the test button always receive this code. But now 10x push test button and receive about 2-3 times the code. So this is tasmota firmware problem?

[Portisch]

No, this device do not use the "standard" PT226x protocol.
