RFlink transmit not working

[markusg1234]

The problem

I can't seem to get rflink to transmit a 433Mz signal. A failed to call service message pops up on the dashboard. Errors occur in log.

This is the first time I have tried to transmit so I might be missing something.

I have no issues with receiving from rflink.

What is version of Home Assistant Core has the issue?

core-2021.8.3

What was the last working version of Home Assistant Core?

unknown

What type of installation are you running?

Home Assistant OS

Integration causing the issue

rflink

Link to integration documentation on our website

https://www.home-assistant.io/integrations/rflink/

Example YAML snippet

switch:
  - platform: rflink
    devices:
      ev1527_04518f_0e:
        name: "test"

binary_sensor:  
    - platform: rflink
      devices:
        ev1527_04518f_0e:      
          name: "Remote Left"

Anything in the logs that might be useful for us?

Hey there @javicalle, mind taking a look at this issue as it has been labeled with an integration (rflink) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

Hi, could you include your RFLink configuration? There are 2 connections types (USB or TCP), if yours is TCP, could you explain how are you exposing the serial interface over TCP.

Regards.

[markusg1234]

Hi, I am using TCP with esp-link v3.0.14

Under the uC console I can see received signals that also Home Assistant detects.

I don't see any logs for when I change this switch to on. All that happens is a failed to call service message pops up. switch:

• platform: rflink devices: ev1527_04518f_0e: name: "test"

Regards.

I have no experience with those kinds of connections, but I think I have read about similar problems. Your case reminds me of this one, but I don't know if it is the same type of configuration as in your case:

• https://github.com/home-assistant/core/issues/43906#issuecomment-775410789

In some cases I have read that it must be configured as 'raw', but it depends on how the connection is configured. Can you check if this may be your problem?

[markusg1234]

Hi, The way I have it set up is mentioned in the documentation on page http://www.home-assistant.io/intergrations/rflink/ using the serial bridge esp-link with a ESP8266 Arduino Mega 2560. I was planning to have the receiver away from the server.

I tried decided to try a direct serial connection to home assistant server and both receive and transmit works correctly which was great to see it work.

On changing back to TCP I saw it work about 1 in 20 on TCP.

Not sure what the issue could be, I'm thinking of now moving the location to where the server is for direct serial connection.

[javicalle]

Hi, when you talk about a "direct serial connection", do you mean a connection via USB cable? Or a TCP (with host and port configuration)?

It seems clear that the RFLink hub is working properly. Could it be a distance problem? Have you tried the same configuration but closer to your HA?

If the problem were in the timeout, you would have the errors in HA but the devices would react to the signals. If the devices are not reacting, I think it must be more of a connectivity issue, either due to range or due to some other cause.

[markusg1234]

Hi,

Sorry I did mean a usb connection works correctly.

I think it is some other cause for TCP not to work one way as I am monitoring the signal to HA which is working but the signal from HA to the RFLink hub is not.

I can see this with the comms monitor built into esp-link.
