Tuya Siren Notes

Template
{"NAME":"Tuya Siren","GPIO":[255,107,255,108,255,255,0,0,255,255,255,255,255],"FLAG":0,"BASE":54}

You must activate the template before using any of the tuya commands below.


Recommended rules for tasmota:
rule1 on system#boot backlog tuyasend4 102,0; tuyasend2 103,300; TuyaSend1 117,0 endon
rule1 1
tuyamcu 11,104

This will set the default alarm length (5min), music (0), volume (0 high), and assign relay1 (power1) to the alarm activation.

The alarm length and music doesn't appear to be retained during power cycles.

hmmm spoke too soon, after cycling the power, no sound comes out of it, no matter what commands i send to it, even if i start from the rule1 setting and repeat what i did first time, changing power from off to on does nothing

Hi, did you fix it ?
I just flashed a MCU Product ID: {"p":"ymf4oruxqx0xlogp","v":"1.0.2","m":0} in 9.3.1 with no sound at all...

Hi, I'm having the same issue. I got rhe same Product ID: {"p":"ymf4oruxqx0xlogp","v":"1.0.2","m":0} and flash it with tuya convert then firmware upgrade to tasmota 9.4.0. There is no sound emited after snding tuyasend command in the console I see the led flashing if TuyaSend4 104,1 enter in the console sending TuyaSend4 104,0 will turn off the flashing led but no sound. are there any solution on making this device work as expect. BTW. I having 2 of the same device and both of then having the same issue no sound.

I have it working without knowing what is the problem. the only thing I did after everything fails is configure mqtt setting on my device to connect to my mqtt server after it restart everything is working like magic. so I'm not sure that this is the real cause of all problem i have or not.

Yes !
You're right !!!
After setting up the MQTT broker, the TuyaSend commands are working.

Good news !

Hi @patrickdk77
I just got a NEDIS siren, and converted it, and tried out your template, it almost works!
This is great work, thanks!
My only problem is that it looses the selected alarm sound after a reboot.
I've changed the rule to:
rule1 on system#boot backlog tuyasend4 102,11; tuyasend2 103,300; TuyaSend1 117,0 endon
But it still uses alarm sound 0 (which is a doorbell).

I have no idea what you are doing, but it's great :-D
I wonder if it can be converted to ESPHome somehow...

It can be, just use the esphome tuya module.

I never published any more details on exactly how to set these up with exact instructions cause I killed two of them in the process of making this and didn't bother to buy a 3rd one. So I don't have a way currently to verify my instructions would work if I made them.

These things do not support rechargeable lithium batteries. using 4.2volts fries these things, so you have to stick to the 3.0v batteries.

I assume this is due to the voltage regulator cannot handle 8.4v, but only supports 6v.

Hey @patrickdk77
Tell me about it, burning items because you want to tinker :-D
When you write eg. "55 aa 03 07 00 05 68 01 00 01 01 79" is that the codes sent via the UART?

Yes as documented at:
