you do need to install the noBle node:

Settings/Manage Palettes/Install
then search for node-red-contrib-noble
and install it

Please write in english !
Emme do you have a simple lua script that sends a notification when battery (user variable) goes < 10 ?
I'm trying to write it with no success...
I had the idea to send a notification when <10 and another one when <5
For both of us (2 tags in the house) in one single script. Is this possible or do I need to write a script for each person ?
Thanks

[emme]

mmh you can do that.... I had it once, but then I delete it

as soon as both thatteries has the same unique prefix (like BattNut_) you can have a script that checks every day and send a message

but I would also suggest you NOT to claim battery as it drawn it quickly

..at least create a device for battery and add a notification on it...

[pimseb]

Too bad you deleted it. I've spend last evening trying to make it work with no luck...
If I do a battery check one time a week will it drain the battery quickly ?

[emme]

what did'n work?... the battery check or the notification script?
if you provide me the device names I can write it back in few hours

[pimseb]

Here is the script I tried to make but it was only for testing purposes and only for one device. We have in fact 2 nuts : one with user variable batterie_pim and the other one with user variable batterie_ben
It doesn't work so don't use it...

Code: Select all

commandArray = {}
if (uservariables_lastupdate['batterie_pim']) then
if (uservariables['batterie_pim']>"5") and (uservariables['batterie_pim']<"12") then
commandArray['SendNotification']='Le niveau de la batterie du tag de pim est faible '
  elseif (uservariables['batterie_pim']<="5")  then
commandArray['SendNotification']='Le niveau de la batterie du tag de pim est extrêmement bas ! Il faut changer la batterie'
  end 
end  
return commandArray

If you can make it working with both tags.... Thx

I'm more familiar with dzVents:

Code: Select all

local lowTrigger = 5
local highTrigger = 12
return {
	on = {
		variables = { 'batterie_*' },
	logging = {
        level = domoticz.LOG_FORCE,
        marker = '[BLE Battery Service]'
        }
    },
	execute = function(dz, devVar)
	    local actValue = tonumber(devVar.value)
        if actValue > lowTrigger and actValue < highTrigger then
            dz.notify('Battery Service','Le niveau de la batterie du tag de pim '..devVar.name..' est faible ')
        elseif actValue <= lowTrigger then 
            dz.notify('Battery Service','Le niveau de la batterie du tag de pim '..devVar.name..' est extrêmement bas ! Il faut changer la batterie')
        end 
    end
}

this should works for any variable whose name start with 'batterie_'

Grazie mille
It works like a charm. I wish I would have to knowledge to write such scripts.
Where could I start ? Better to learn lua or dzVents ? Is there a tutorial somewhere ?

[emme]

I did not even know LUA!!!

I took 3 month to understand LUA for domoticz related issues.... you you would not take longer

at the end thay are just if.. then.. else... end statements...
start with this script and "unpack" it to understand what it is doing....

then I create a pushbutton named TEST that trigger a script for... well.. test purpose

dzVents is LUA program language in a json string... so it has few statements to well understand but after that it is quite easy!

Danny made a great work even on the tutorial!!!
