probably a stupid question, but I'm assuming I have to enter the full path to the script in crontab, ie: /pi/domoticz/scripts/python/python3 domoticz.py?

[Itschi]

Yes, you need to enter the full path.

I think

Thanks, that was it!

great work all!

I updated my python to 3. installed request.
have the correct mac and with hcitool scan I see Flower Care.

[trixwood]

the second try looks like it has trouble reading it... it retries... and succeeded

The first try probably related to bad error handling... I usually have issues with new ones...

https://github.com/open-homeautomation/miflora/issues/7

btw conductivity appears to be soil fertility...

My version of the domoticz script... (you have to sleep between readings different devices, or else you get the transport errors...

https://github.com/Tristan79/miflora

If all else fails you could try the mtqq version...:

And some nice background:

[trixwood]

Also note that moisture is in procents % not soil moisture cb... that is a whole other unit...

And soil fertility should be above 500, for blocky or lua use (according to their app)

connect error: Transport endpoint is not connected (107)

if the sensor is more then 4-5 meters from a pi3 (internal) bluetooth, it seems it's really struggling... to get a reading...
Is that what you experienced?

I'm getting abnormal value sometimes, all of this more than 1000-2000, my sensors (8 pcs) located less than 1 meter and one about 3 meters from my RPi3. And notification: "Domoticz: Battery Low: Adenium obesum (Level: Low)", as example. In next request everything is ok.

With 6 really close by I get no (transport) retry errors, now with 11, usually it has to retry with 2 or 3... but much wider apart (in circle range of 5 meters of the pi) Still all value's correct read and bridged to domoticz, no spikes, but I will monitor
And I noticed one of the lux sensors was constant at 47094... (112630 in the app itself)... I think that's broken...

Will update in a couple of weeks about connectivity when I have 21 all around the house

No more plant dehydration and starvation Poor little buggers, suffered long enough.

I also have abnormal value's, still think there are a lot of bugs in the code...

LOL, that's a forest you live in

[trixwood]

Well yeah if you put them all together it would, but spread out in a room. It does what plants do best, be part of the scenery. You hardly notice them...

Uhm, I patched the false readings...

The bad readings I got where:

fertility 26231
moisture 136
temperature 4804.2
lux 61149

consistently... so I was lazy and patch the domoticz scripts... let it max retry 3 times if temperatures are over 200 degree celcius...

Should remove any spikes...

Greate work! Thx.

[corbin]

fertility 26231
moisture 136
temperature 4804.2
lux 61149

so when you got 1 elevated reading, all the others readings were elevated at the same time?

Yes, and all others

[corbin]

Yes, and all others

thanks, I had seen the high readings, but haven't had time to investigate. I've modified the script to exit on a temp reading over 200 as trixwood did.

Also, I'm having a hard time keeping the fertility/conductivity over 500, can anyone offer some advice on this?
