Any plan to implement Ethernet GW?

Don't forget to use the correct ip address of your gateway in your network.

drock1985

It works! Found my motion sensor with ease. Will start adding lights now shortly

Thanks again, loving this.

EDIT: Quick question: To autostart this, would I just use the normal Home-Assistant instructions in the virtualenv, or is there another method to do it?

:thumbsup:

When you have time, can you run git log and tell me the top commit message, so I know which version you are using.

Regarding autostart, no I don't think you can use the normal instructions together with the virtualenv. You could write a script, that changes to the virtualenv and starts hass, and run that script at login or similar.

If you don't have another production install of home assistant on the computer, you can skip the virtualenv alltogether and just do:

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

or if you want to install as root:

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

This way you should be able to autostart the usual way, per instructions on the web.

But then if you want to test an update from me, you have to make sure you uninstall everything correctly and manually remove ~/.homeassistant/lib before you install again.

    Add mysensors tcp ethernet gateway

    * Replace CONF_PORT with CONF_DEVICE and ATTR_PORT with ATTR_DEVICE.
    * Add tcp_port in config.
    * Use fork pymysensors repo, temporarily.
    * Try to guess if tcp or serial gateway is configured, by validating
        device name as an ip address. If successful setup tcp gateway, if it
        fails, setup serial gateway.
    * Update device_state_attributes to show correct device, ethernet or
        serial.

Sorry, I forgot I've only updated the pymysensors project, so you checking the home-assistant git log is no use. Well, I think your're running the lastest version anyway, since you got it working just now. Everything should be ok.

Let me know if you experience any problems.

If everything seems ok for you after some time of testing, I don't see why we can't release this very soon. My limited testing after the lastest update, show no problems.

Dave Dan

Hey @martinhjelmare,

I finally got this working.

I'm doing tests with a couple of multi-sensors (Temp, Hum, Light & motion). The discovery worked very well, no issue at all after following all the above steps.

What I'm not seeing wotking are the updates. I always see the same values. I'm checking messages with MYSController and I see the GW is receiving the events and updates but I can't see new values showing in the portal.

Still testing ...

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.

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.
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?

Any plan to implement Ethernet GW?
