Is it possible to have smartmeter2mqtt running in Home Assistant using NodeRed?

[alexboss]

Hi guys, sorry to come back with this again. This is following my successful installation as described on #21 (comment)

I ordered and received a SlimmeLezer+ from @zuidwijk which works perfectly fine out of the box. Unfortunately, the wifi signal often breaks and it messes up the real-time curves of electricity consumption (which I'll need in winter time to precisely monitor consumption when the heating will be switched on and the heat pumps working).

So, I'm back with the SlimmeLezer P1 and smartmeter2mqtt.

As explained in the past, I made it work using an intermediate computer to run smartmeter2mqtt and then publish to the mqtt of home assistant installed on raspberry pi.

Now my idea is: instead of having smarmeter2mqtt on an intermediate computer, why not having it on the raspberry pi where home assistant is installed and having it running through NodeRed ?

So I installed NodeRed and configured it with these NPM packages:

• [email protected] + serialport
  And system packages:
• python3, make, g++ and linux-headers

See

Now, I'm trying to start smartmeter2mqtt through the NodeRed interface using the exec component, unfortunately, it's like the parameters are never taken into consideration and consequently can't have it running.

I always get the feedback: Port or socket required instead of getting 1.7.0-beta.9 for instance.

Would you have an idea if theoretically it could work this way, and if so, how to pass input parameters to smartmeter2mqtt through NodeRed ?

Thank you and best regards.
