Any plan to implement Ethernet GW?

[martinhjelmare]

@Dave-Dan

Do you mean that the sensors are not showing the latest values in the gui?

If the last value from a sensor is the same as the previous value, a state change won't happen. So the value will be reported as being as old as the previous value. Could this explain what you see?

[Dave Dan]

actually, I just got it working ...

yes, I was referrring to that. The way I have built the sensor is that everytime a movement is detected is sending all sensors statuses to the GW. This sensors are designed to be plugged (no battery powered) so no concern on power consumption.

I restarted the server and now updates are working.

What I'm seeing in the log is constantly this message:
16-03-14 10:39:53 INFO (Thread-9) [mysensors.mysensors] Permission denied when writing to /home/pi/dev/home-assistant/path/mysensors3.json

If I'm not wrong this is the persistence.

Apart of this I now see updates coming in ...

[martinhjelmare]

Good!

The path to the persistence file must exist, not the file itself, but the directory tree above, and hass should have write permission to it.

I usually put the file in the same directory as configuration.yml.

[Dave Dan]

Ok, couple of things that I'm seeing now.

1. Everytime I restart the server the MySensor nodes are no longer in the system. I have to restart them to get them in again. All of them are in the persistence file.

2. Now i can only have 1 node added.
   While in the persistence file I see multiple nodes, once I add one of them I can't add anymore. No error if fired (at least not that I've seen).

[martinhjelmare]

@Dave-Dan

Can you attach the persistence file here and post your config, and I'll take a look?

[Dave Dan]

Sure!

Consistence file:

{"156": {"sketch_version": null, "children": {}, "battery_level": 0, "sketch_name": null, "type": 17, "sensor_id": 156}, "102": {"sketch_version": null, "children": {}, "battery_level": 0, "sketch_name": null, "type": 17, "sensor_id": 102}}

the Configuration is very light. Actually is the by default config and i just added this to test MySensors:

mysensors:
  gateways:
    - device: 192.168.1.X
      persistence_file: '/home/pi/.homeassistant/MSPersistence.json'
      tcp_port: 5003
  debug: true
  persistence: true
  version: '1.5'

let me know if you need anything else.

[martinhjelmare]

In the persistence file I can see two issues.

Sketch name is null for both nodes.
Both nodes don't have any children.

Are you using a non default example sketch, if so can you post it?

[Dave Dan]

hey Martin,

that's correct, those are the 2 items I saw that was little curious about.

The sketch I'm using, while custom, is a mix of different sketches that can be found in the MySensors page.

As you'll see below, each node (which are identical) have all the information (Sketch name, version, etc). And all of them have 4 childs:
- Ambient Humidity
- Ambient Temperature
- Ambient Light
- Movement (Motion Sensor Trip).

But I might have something wrong so ... happy to learn! :)

Hey @martinhjelmare

Does the above reply to @drock1985 means that I can do a basic installation as per https://home-assistant.io/

pip3 install homeassistant
hass --open-ui

followed by

sudo pip3 install "https://github.com/MartinHjelmare/home-assistant/archive/mysensors-tcp-gateway.zip"

and will have a valid testing env without going into all the above steps of creating a virtualenv??

If so I'd rather more this avenue because I can clean up everything with a new installation, install the zip and have a new testing env in minutes :)

[martinhjelmare]

@Dave-Dan

I can't see any big issues with your sketch, just one small:

I guess this is a typo:

#defin TEMP_CORRECTION 2

Since your sketch looks ok, I think something must have gone wrong with the communication between node and gateway. Have you been monitoring the comm, with a serial monitor, on the node side for example, to make sure all messages are sent ok?

[martinhjelmare]

@Dave-Dan

The zip file you install from my github account, is the mysensors tcp gateway branch of home-assistant. So you shouldn't install home-assistant first, if you're going to install my branch.

If you don't have any other version of home-assistant that you wish to keep, on the same computer, you can install my branch directly. You just have to make sure you uninstall it and remove ~/.homeassistant/lib before installing an update from me, if I commit some updates.

Yeah, setting up a dev machine can be a hassle the first time, and not so useful if you're not developing with it.

[Dave Dan]

@martinhjelmare

thanks for the hint ... definetly a typo :$

Yes, I'm monitoring the GW with MYSController as my GW is ethernet and I see all messages showing with no issue. But, I'll be happy to review again. :)

[martinhjelmare]

@Dave-Dan

Yes, please start from the beginning:

Remove the persistence file
Start hass
Wait until you see that hass has (:smile:) connected to the gateway
Start a node
Start the next node

If you can post the serial log from that here, and also the log from hass, that would be great.

[drock1985]

@martinhjelmare

Haven't had any issues with the sensors I have on my Dev unit; so far so good.

Are you thinking of releasing the ethernet GW code in this weeks update?

[Andrew Sanjanwala]

@martinhjelmare

Though I'm eager to try, I can't actually launch the Ethernet Gateway branch in a Windows environment. The best error I can provide is the generic failed to create process on calling hass. Platform is Windows Home Server 2011 running Python 3.5.1. All previous and current release branches of home assistant launch without error.

Any thoughts or other steps I can take to debug it further?

[martinhjelmare]

@drock1985

Good to hear. Have you tried connecting more than one node to the gateway at the same time?

Unfortunately I don't think it will make this release, cause I won't have time until Sunday, and the release might be finished before that. I will add some updates this weekend that you are welcome to try. After that we should be ready for release.

[martinhjelmare]

@Andrew-Sanjanwala

My experience with python on Windows is very limited. How do you normally start home assistant?

[Andrew Sanjanwala]

@martinhjelmare

I typically launch either using hass or hass --open-ui from an administrative powershell session. No-go in either of these two cases.

[martinhjelmare]

@Andrew-Sanjanwala

Did you install directly from my github branch using pip?

[Andrew Sanjanwala]

Alright, false alarm. Root issue in my case was a faulty environment and/or operator that resulted in binaries being compiled for the wrong platform.

Once corrected, it compiled and launched your branch and connected to the gateway without incident. Next up is experimenting with the nodes and actuators. I'll see if the persistence file can be written to.
