433mhz, infrared IR to and from MQTT on ESP8266

AhmadK · March 7, 2019, 8:43pm

I don’t quite get what you mean. You can use either Mega (with Ethernet shield) OR ESP.
As a user of both RFLink@Mega and OMG@Arduino/ESP, I’d say that the easiest/cheapest/fastest way to have a play would be something like Wemos d1 mini - currently it is working as the main 433toMQTT bridge in my HA setup, and it does the job very well.
However, it’s better to check if a software of your choice supports your RF device as not all of them are standard and you might end up having 50-50 chance

I think what I meant was, RFLink seems to require an arduino board, and can use an ESP8266 for wifi connectivity.
Other solutions seem to just use an ESP8266 for same (or similar) function.

I’ve got a few boards lying around to play with though, so I’ll see how I go

RFLink works on Arduino MEGA only.
You connect the MEGA to RPi with a USB cable to get the information in HA, that the way it works

If you go OMG way though, your bridge needs to be connected to a network somehow anyway.
It can be Arduino UNO/MEGA/etc + a Ethernet shield.
It can be ESP8266 alone.
But I don’t think you can use Arduino with ESP as a network interface.

Hope it makes more sense.

For info OMG can be used on Sonoff RF Bridge with pilight, extending consequently the list of compatible protocols, here is how :

Hi, I’ve just found OpenMQTTGateway, is looks like a nice way of working with 433Mhz devices.

Is there a way I can get it to talk to my MQTT server using TLS?

Using Tasmota I use the fingerprint method here:

Can I do something similar using OpenMQTTGateway?

Thanks

Hi @Codec303

Unfortunately not yet

Codec303 · July 19, 2019, 5:34pm

Ah OK, thanks for letting me know. I think I may be able to find some sort of workaround

@1technophile

Hi, hoping you could assist with a Sonoff RF Bridge?

Flashed RFBRIDGE_OpenMQTTGateway_V092.zip

Messed around a whole lot until I finally found that the default device name is OpenMQTTGateway_SRFB and not the default OpenMQTTGateway.

Got binary sensors working,

binary_sensor:
  - platform: mqtt
    name: "OpenMQTTGateway"
    state_topic: "home/OpenMQTTGateway_SRFB/LWT"
    payload_on: "online"
    payload_off: "offline"
    device_class: "connectivity"

  - platform: mqtt
    name: "Door RF"
    state_topic: "home/OpenMQTTGateway_SRFB/SRFBtoMQTT"
    value_template: "{{ value_json.value}}"
    json_attributes_topic: '["protocol"]'
    payload_on: "13655790"
    payload_off: "13655783"
    device_class: opening

  - platform: mqtt
    name: "Button RF"
    state_topic: "home/OpenMQTTGateway_SRFB/SRFBtoMQTT"
    value_template: "{{ value_json.value}}"
    json_attributes_topic: '["protocol"]'
    payload_on: "3624197"
    off_delay: "1"
    
  - platform: mqtt
    name: "Motion RF"
    state_topic: "home/OpenMQTTGateway_SRFB/SRFBtoMQTT"
    value_template: "{{ value_json.value}}"
    json_attributes_topic: '["protocol"]'
    payload_on: "15906678"
    device_class: Motion
    off_delay: "10"

Regular sensors,

sensor:
  - platform: mqtt 
    name: "Wifi OpenGateway 8266" 
    state_topic: "home/OpenMQTTGateway_SRFB/SYStoMQTT"
    value_template: "{{ value_json.rssi}}"
    json_attributes_topic: "home/OpenMQTTGateway_SRFB/SYStoMQTT"

  - platform: mqtt
    name: "OpenGateway input"
    state_topic: "home/OpenMQTTGateway_SRFB/SRFBtoMQTT"
    value_template: "{{ value_json.value}}"
    json_attributes_topic: "home/OpenMQTTGateway_SRFB/SYStoMQTT"

And lastly, a switch.

switch:
  - platform: mqtt
    name: "test send"
    state_topic: "home/OpenMQTTGateway_SRFB/MQTTtoSRFB"
    command_topic: "home/OpenMQTTGateway_SRFB/commands/MQTTtoSRFB"
    payload_on: "3624197"
    payload_off: "3624197"
    optimistic: false
    retain: false

The problems.

The sensor for input, used to keep showing data/codes. Now it disappears instantly, usually too quickly to highlight or copy. Mostly it’s just blank.
The switch seems to send. There’s a flicker on the RF LED on the Sonoff, but the receiving device doesn’t change/do anything. Tried with a RGB controller and a doorbell. (I can capture the remote codes via MQTTlens
Can’t read anything from serial monitor. Just prints rows of ⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮
I was using the Arduino IDE on 115200.
Getting false readings on the motion sensor now. Shows motion, but there’s no movement in the room.

I had a nodemcu, and cheap rf kit previously. Same issue with the input sensor, and couldn’t send, but no false positives, and could read get data from serial monitor. Was thinking maybe my transmitter hardware was faulty, so I got the Sonoff today, but now I still can’t send…

Using Home assistant 0.96.5 and OpenMQTTGateway v0.9.2 as mentioned above.

Any ideas on how to resolve these?

Thanks in advance!

Hi,

I suppose you see this behaviour on HA isn’t it? Could you check what is happening on the mqtt broker side and post the results?

Could you indicate the receiving device type/model?

For the sonoff rf bridge the speed has to be set to 19200

Could you post what you are seeing on the mqtt broker ?

derikj · August 7, 2019, 6:58pm

Hi,

Yes, it’s on Home Assistant, and using this broker, which mainly just shows connections.

Logbook also doesn’t show the code, just a blank space.

Do now have serial monitor so when pressing the doorbell button:

MQTTlens for button as well.

  "delay": 5200,
  "val_Tlow": 190,
  "val_Thigh": 520,
  "value": 3624197
}

And then serial monitor when I activate the switch to send same signal as received above.

Hey I got a callback 
MQTTtoSRFB prts
[RFBRIDGE] Sending MESSAGE '%s' %d time(s)


⸮⸮%@⸮7MU

And MQTTlens for switch too.

Could you indicate the receiving device type/model?

Doorbell is a “local” SA brand. Ellies. Not a super lot of info.
RGB Controller is one of these

If I can receive the codes, I should be able to send them as well, or is there something regarding RF I’m missing?

For the sonoff rf bridge the speed has to be set to 19200

This is working now, thanks!

I’ll keep an eye on the false readings issue. Hasn’t happened again today.

Does any of this help narrow down the issue with sending? From the serial monitor log is does seem like something’s going wrong.

Thanks again!

Regarding the sensor it seems to be related to HA configuration, did you tried this configuration

Regarding MQTTtoSRFB did you uncommented simpleReceiving in your configuration (user_config.h) indeed your yaml definition correspond to simpleReceiving and per default OMG expect json.
You can either uncomment simpleReceiving or modify your yaml to make HA send json.

derikj · August 7, 2019, 8:18pm

Hi,

I did try those, but get errors relating to json_attributes needing to be updated to
json_attributes_topic. If I change my sensor from “value” to any of those others, (version/uptime/etc) it works, and displays without disappearing.

MQTTtoSRFB - I didn’t un-comment anything. Just flashed the pre-compiled .bin file.
What was the default set to on RFBRIDGE_OpenMQTTGateway_V092.zip?

Thanks!

1technophile · August 8, 2019, 8:21pm

Hi,

Does the value disappearing event correspond to an mqtt publication ?
You could subscribe to all the subjects to see that. Or maybe use mqtt explorer.
I m suspecting that simplePublishing overwrite the values of jsonPublishing.

1technophile · August 10, 2019, 8:09am

For info I have removed simplePublishing from binaries file, you can try to upload again if you want to see if it was due to that.

derikj · August 10, 2019, 2:55pm

Hi, thanks. I’ve managed with Tasmota for now, but I’ll try this on my other setup. Which bin was modified?

1technophile · August 10, 2019, 3:42pm

All were modified. Indeed there is no need of simplePublishing per default.

Something happened to the images at the site/blog. May you check, plz?

Thanks for pointing that, issue corrected!

Eeeeeediot · June 29, 2020, 2:20pm

Hi,

just installed your project @1technophile and almost got it working!

The following code allows me to sync the HA switch to the button presses on my remote. However, the actual HA switch immediatly reverts to off when i try and switch it on. I does actually turn on my outlet/plug but the state is wrong. The state moves to the ON position if i press my remote.

Any ideas?
