MMM-SensorGateway

sdetweil

@mattileh maybe you could give a few more words about SensorGateway… What do you need to make the module work? what sensors?

Thanks! This was something what I was wishing for to happen. Previously I used influx+grafana setup to get info to MM and it was quite keen setup to corrupt memory cards. I dont need data to be stored anywhere so this was more than good solution to get info from ruuvitags to MM.

@thap Hi!, great to hear that you found the module usefull as well.
Please let me know if there was any problems in replicating the gateway setup or any other changes required to the instructions.

Tried this with 3b/3b+ (python 2.7/3.6), when installing module I get the following error:

I can see the temperature with “ruuvitag -f” in console. If I try to see the status with “sudo service local_blegateway status” I get:

pi@raspberrypi:~ $ sudo service local_blegateway status

Any hints?

@dmd Hi!, Python 2.7.16 is the exact python version I’ve used.

the exec module warning is expected, is there something in the snippet you sent that indicates that something went wrong in the module installation?

btw, how did the service installation itself go? (there is an expected output in the instructions) and can you try running the gateway python script directly? e.g. :

sudo python bleAdvWebSocket.py

and post the results here.

@mattileh I gt exactly the same error as @dmd. When I run bleAdvWebSocket.py manually I get the following:

pi@mirror-pi:~/MagicMirror/modules/MMM-SensorGateway/gateway $ python bleAdvWebSocket.py 
Traceback (most recent call last):
  File "bleAdvWebSocket.py", line 13, in module
    import websocket
ImportError: No module named websocket

There is a lot of install work for this module. Did u guys run the install script per the readme?

mattileh

@stickymongoose Hi! the websocket module is installed in the gateway module installation - can you double check you’ve ran README.md:41

* run `npm install` in module's directory to install websocket and exec modules.

also the local run of advSocket needs root access so please run it with the snippet above (e.g. with sudo in front, or from root user)

Jo-Rien

Is there a fix to the before mentioned errors?

mattileh

@Jo-Rien I’m not quite sure yet what are the problems, as sdetweil mentioned the module has quite extensive setup part elaborated in the readme.md. and also that one issue I’d like to see answered if the sudo fixed it.

I could probably try to do a “clean install” during July’s time and update the instructions if found something.
