script to convert serial to mqtt?
-
Hi,
I am trying to find a working script that translates messages from my serial gateway to mqtt so that they are equivalent (in structure and topics) to a mysensors mqtt-gateway.
The reason I would like this is that I can't use my rfm69h chip on my raspberry pi atm but I can use a serial gateway. As soon as I can use the chip I would like to use the mqtt gateway. And I don't want to set everything up from scratch in home assistant then.
Can anybody recommend a working script for this? I have found a few very old ones and one that's fairly recent, but the ones I found that let me set subscribe and publish topics didn't accept username and passwort for the mqtt broker and the ones that did used a different messaging structure.
Thanks for the help!

I have no experience with Home Assistant, but in Domoticz I can just switch my gateways from one protocol to another. Maybe Home Assistant can do something similar?

I haven't tested it, but this one seems to fit what you need

@electrik perfect, thank you both!

You're welcome. Can you let us know how that program worked?

You could also use node-red for this (and many other useful things)

I've tried this in the past, but couldn't get it to work completely. It worked only one way, as for both send and receive a serial port node was needed, and only one of them could have access to the serial port at a time.

@electrik
I haven't tried the script since using a serial gateway as is in home assistant was problem free and from what I have seen I can seamlessly switch to an mqtt broker in the future.

I am using appdaemon for my automation and I wouldn't want to install node red just for the conversion. Or are there automations that node red can that appdaemon can't?
