I bought these wireless/radio switches by mistake: QIACHIP – interrupteur de commande à distance numérique sans fil, relais 1/2/3 voies AC 220V RF, panneau de ventilateur de plafond, interrupteur de commande pour ampoule | AliExpress
(I thought that those will work on RF433MHz). I decided to test if all modules work before closing my order and found that remote controllers of 2-relay modules are seen by my Sonoff RF / SRFB.
It can track all 4 buttons, here’s what I see my console window:
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“raw”:“1DA601720410003DA4”,“delay”:7590,“val_Tlow”:370,“val_Thigh”:1040,“value”:15780} - B
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“raw”:“1DEC0168041A003DA8”,“delay”:7660,“val_Tlow”:360,“val_Thigh”:1050,“value”:15784} - A
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“raw”:“1DF6015E0424003DA2”,“delay”:7670,“val_Tlow”:350,“val_Thigh”:1060,“value”:15778} - OFF
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“raw”:“1DEC01720410003DA1”,“delay”:7660,“val_Tlow”:370,“val_Thigh”:1040,“value”:15777} - SLEEP
So I think that those 2-relay modules work on 433MHz and I should be able to control relays, correct?
But I tried different requests (according to RF gateways (433mhz/315mhz) | OpenMQTTGateway v1.4.0) and didn’t get any result at all:
mosquitto_pub -t homeassistant/OpenMQTTGateway_SRFB/commands/MQTTtoSRFB -m ‘{“value”:15784}’
mosquitto_pub -t homeassistant/OpenMQTTGateway_SRFB/commands/MQTTtoSRFB/Tlow_350/Thigh_1080/Tsyn_8640 -m ‘{“delay”:8640,“val_Tlow”:350,“val_Thigh”:1080,“value”:15784}’
mosquitto_pub -t homeassistant/OpenMQTTGateway_SRFB/commands/MQTTtoSRFB/Raw -m ‘{“raw”:“1DEC0168041A003DA8”}’
I can see these messages in subscriber while submitting those commands:
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“value”:15784}
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“delay”:8640,“val_Tlow”:350,“val_Thigh”:1080,“value”:15784}
homeassistant/OpenMQTTGateway_SRFB/SRFBtoMQTT {“raw”:“1DEC03FC0190003DA8”,“delay”:7660,“val_Tlow”:1020,“val_Thigh”:400,“value”:15784}
and so on.
Can anyone help me with this? Do I submit commands correctly? I have never did this before, only received messages from water leakage and PIR sensors. Am I doing all right?
I understand that since there’s nothing mentioned about RF 433MHz in product description then those may work on some propriatery protocol (I see nothing on MQTT while testing single-relay modules), but I do see messages from 2-relay modules remote controllers! I unpacked the box and I see there’s some module onboard that controls those 2 relays, Qiachip FD-136S, but unfortunately I can’t find anything about that module.
Here’s some pictures:
Any idea is highly appreciated! Thanks!
PS: I ordered another RF relay, this one looks correct: https://www.aliexpress.com/item/32828221778.html
