On RPI 2 with Wheezy i have a problem in the wiki

Python-to-bluetooth

Next, Install Python3 and the required Python3 libraries that let Python script talk to Bluetooth.

Can you share the error message?

Dunno why, but on my OrangePi myflora works only when i run hcitool lescan before script
so i modifed script that it runs hcitool lescan for few seconds, then all works
(also changed hcitool lescan to run without sudo)
i know that its quite dirty but it works... for me
here is my modifed script

Seems that on my Pi2 with the Domoticz image, the command isn't pip3 but pip-3.2

So close now but But I still recieve Error:

I downloaded the new and updated miflora_poller.py from https://github.com/open-homeautomation/ ... ant-sensor but still recive the same error
I found my ID using : sudo hcitool lescan)
C4:7C:8D:62:0C:81 Flower care

I edit demo.py with this but when I run it I get the following errors:

How can I connect to the sensor and watch RSSI with scan on? 

Thank you

[madrian]

I am triying:

Code: Select all

@orangepizero:~/bluetoothctl
[bluetooth]# scan on

And I see many Servicedata Value lines....how I can filter out only RSSI?

I solved this by manually update to python 3.4

[micksel]

I can see in the python script that the battery parameter is also sent when updating the values.

Like: domoticzrequest("http://" + domoticzserver + "/json.htm?type=command&param=udevice&idx=" + idx_temp + "&nvalue=0&svalue=" + val_temp + "&battery=" + val_bat)

How can I see this value in domotics?

Right under the Devices tab Check the little green battery icon, and in that row.

Feeling like an idiot, thanks.

Dear All,

I bought a MiFlora Plant pin and followed the wiki.

I run domoticz on a raspberry 3

I discovered my device with the command

Code: Select all

sudo hcitool lescan

it showed C4:7C:8D:63:62:1E Flower care

I used the domoticz.py from the wiki
I updated this value in domoticz.py and when I now run

Code: Select all

pi@raspberrypi_V3:~ $ /usr/bin/python3 /home/pi/dev-domoticz/scripts/python/miflora/domoticz.py

I get the following response:

1: Varen (weet ik niet)
connect: Device or resource busy (16) (many times)

Anyone any idea why this is happening? I tried already for a couple of hours but no other results. Do I need to change something else?
It is a bit a pity that I can't read the values of the flower pin into domoticz

[micksel]

I got that error message when I still was connected with my Phone. Is that the case for you?

[bertbigb]

That was exactly the case, now it is working fine. Thanks for your reaction

[LouiS22]

Got a firmware upgrade, new version is 2.9.4. I've upgraded, python script is still working (those who wonder).

[ilpier]

There is no way for Windows?

[micksel]

There is no way for Windows?

python exit for windows but not sure about all the moduls, maybe easier just to emulate a Linux system on win

Hi,

I have a raspberry PI 3 with bluetooth, MQTT and Domoticz installed.
I can read through the lua script all my plant pins. So far so good.
What I would like is to send the values from the plantpins over MQTT to another domoticz system running on Synology.
From the PI, i tested and i can send messages to the other domoticz system on Synology
Can anyone help me to point out how to do or what to change in the script to make this possible?

Thanks for your help.

[pvm]

You can also make a slave Domoticz and have Domoticz sent these values over to the other one
