Domoticz full integration

[AWI]

In the quest for Domoticz full integration, I have been doing some prototyping in Python. Domoticz has very capable JSON support and virtual device types so we can do without "full integration" .
My python script is built around a 'dictionary' based Database with a hardcoded MySensor-Domoticz translation. The script is running stable with 20+ sensor/actuators and limited cpu load on raspberry pi (15%).

What is next:

• dynamic sensor inclusion i.s.o. fixed nodes.
• more sensor types and support for combined devices (e.g. Temp, Hum, Baro)
• (sqlite i.s.o. python dictionary)

dependencies: requests, json

anybody interested?

You can find the attempt at: Domoticz-MySensors
all suggestions welcome..

@AWI

That would be awesome!

@AWI That would be pretty awesome!
If I can help anyhow, just say so.

Currently I'm running Domoticz with custom-built gateway on MEGA, but could probably start switching whole thing to MySensors as whole setup use nRF24L01 :-)

How can I help? Or is it ready for tests?

[AWI]

@andriej It is ready for test. Just edit the your setup in the header and adapt "Sensor_DB" to your setup. Nothing really fancy.

[andriej]

@AWI I'm after first test and that's what I get just after running the code:

# python mysensors-dom.py
2015-01-17 02:59:41 Start
('Wrong/No input from MySensors gateway', ValueError('No JSON object could be decoded',))
('Wrong/No input from MySensors gateway', ValueError('No JSON object could be decoded',))
('Wrong/No input from MySensors gateway', ValueError('No JSON object could be decoded',))
0;0;3;0;14;Gateway startup complete.
('Wrong/No input from MySensors gateway', ValueError('No JSON object could be decoded',))

Are these desired messages?
What I'm supposed to do later on?

[andriej]

I've managed to get it to work.
First issue - since always I've reported temperature and humidity altogether (from DHT sensors).
Currently I can't specify one IDX for two values and I can't see in code where I could put two values to report in Domoticz at once.
They use to be reported in one URL.

[AWI]

Good to see you are taking the jump... What you see in the first test is are generic error messages which can be generated in many place. There is a "catch-all" exception handler on the main loop, I suggest you take out the word "ValueError". After that the script will come to a halt and indicate where it went wrong.

I am 'almost' in the next major update. I hope to upload today .

Good luck!

[AWI]

@hek I am almost done with the python -Domoticz "full integration" but strugling with a few message types. The code for Vera is a good source for information but it is hard to determine the role of the controller in the construction/routing of the network. For now I assumed only node numbering and keeping track of the sensors. Is the controller supposed to do something with the relay nodes? what is the function of the I_CHILDREN message?

[hek]

Just skip it. It's deprecated and will be removed.

[AWI]

@andriej I will be posting a new version tomorrow which adds maximum functionality for Domoticz (from my view): combined sensors (trick), node numbering, inclusion and an external database in JSON. I will keep it running tonight to test the stability. ...

[AWI]

Major update (but still very beta...,) supports:

• dynamic sensor inclusion i.s.o. fixed nodes.
• more sensor types and support for combined domoticz devices (e.g. Temp, Hum, Baro)
• external JSON database

The python script is built around a 'dictionary' based Database with the MySensor-Domoticz translation. The script is running stable with 20+ sensor/actuators and limited cpu load on raspberry pi (15%).

Known issues:

• You need to edit the JSON database yourself if you need combined Domoticz devices eg. (Temp/Hum/Baro). Not difficult
• Need to create Switch types yourself in Domoticz , then assign these in the database
• Usage/power not supported yet (need a "multiple value" trick..)

You can find the attempt at: Domoticz-MySensors with a small instruction in the first few lines

all suggestions welcome..

@AWI, great work!

You should probably post something over at Domoticz forum as well.

Domoticz:

Starting with a native implementation, thanks to Ad for providing the RF interfaces.

Maybe best (for domoticz) to continue on the forum,
i need serial logs of all possible combinations and meaning

node-id;child-sensor-id;message-type;ack;sub-type;payload

we developers probably have to do some special tricks to get some nice sensors

for instance, it would be nice if there where subtypes for:

• Temp+Hum
• Temp+Hum+Baro
• Kwh+Watt
• Wind+Gust+Direction

I can not watch this forum, if you want to contribute, plz use the domoticz forum

@Rob-Peters

Hi, great to see you here! I'll send you my contact details if you have any specific questions.
@AWI seems to have implemented most of the logic necessary.

[andriej]

In latest release of Domoticz I can see first implementations of MySensors!
Maybe it's worth a shot for someone to register on Domoticz forum and help their team out?

[AWI]

@andriej Hi, GizMoCuz is working on it (2 reply's before) asked for serial log of all possible combinations. I am trying to help out, but some help and priority setting is more than welcome.

[epierre]

Hello,

I've answered to Rob sending some of my logs and a link to my interface, I guess seeing a link between values and JSON will help a bit ;-).

@hek we've not settled about gas values, no ?

[hek]

@epierre
Sort of... But I will probably not change anything in 1.4.

[GizMoCuz]

Posted a new beta of domoticz.
Lots have been changed

If anyone can supply me with serial log messages of:
S_LIGHT_LEVEL
S_WATT
S_KWH

That would be helpfull

With regards,
Rob
