Implemented in Latest beta 2023.2 dd18/9/2023 thanks to @gizmocuz.

Thanks @gizmocuz for having implemented that

A simpler method is to use a low pass filter. After a while it becomes equivalent to the average value.

Eg, to get the average over 60 values, loop on this formula each time you get a new value :
Tavg=(59*Tavg+T)/60

I back up this request. It would be very nice to extend the thermostat widget into a custom setpoint widget

It works Thanks for pointing this out

Nobody ?

Hi All !

I'm in need to update a variable on a remote domoticz via json & curl :
- remote domoticz is IP accessible on port 8080
- a dedicated user exists, with "user" rights on a remote domoticz and a few devices authorised
- this user can be successfuly used to update remotely that devices via ...

Very interesting project ! Thanks for sharing [emoji846]

I need to rise a warning in using that kind of flow sensors on a swimming pool filtration circuit. I never managed to keep one of them operating more than a few months. And the breakdowns come after +/- the same amount of M3 pumped through them. I guess they are just not designed to count such a ...

You're right !!

Here is the full code :

function os.capture(cmd, raw)
local f = assert(io.popen(cmd, 'r'))
local s = assert(f:read('*a'))
f:close()
if raw then return s end
s = string.gsub(s, '^%s+', '')
s = string.gsub(s, '%s+$', '')
s = string.gsub(s, '[\n\r]+', ' ')
return s
end ...

I've had the same need in lua, so I wrote the following function :


function getPref(dbName,key)
-- Retourne une valeur depuis les préférences de domoticz
-- Key doit correspondre à l'une des lignes de la table preference
sql='sqlite3 '..dbName..' "select nValue,sValue from Preferences where ...

I back up the point for the icon, it would be nice

Regarding export of data, I had this need for electricity, and choose to export to a MySQL dB. Simply by running an SQL query via an os.execute in a lua script. I think we could do the same here

Suggestion:
The script results in display at the widget with many digitis which are not effective.
Inserting a 'round'-function you can limit to a more meaningful display.

You're right about displaying not meaningful digits. The problem is calculating ET every minutes, or even hours, gives ...

Wow ! That's a big mast

Here is my script to calculate EVP based on weather sensors. Calculations are from Penman Monteith formula and FAO-56 method ( http://edis.ifas.ufl.edu/pdffiles/ae/ae45900.pdf ). The code below is an extraction from my global watering script, so maybe I introduced some syntax bug on the process. If ...

I'm calculating ET from meteo values for watering my garden. I successful store the result in a dummy rain sensor, it does the job quite well

Did you also put an automatic chlorine regulator?
Yes ; I have a full setup filtration+pH+chlorine

Same as for the ph but with another probe?
Yes, an ORP probe connected to a dedicated phidget 1130 card

Same as for the ph but with another probe?
You can have a look at this topic in the ...

I would be curious too about other's experience. Here it's still operating. After having selected the right material for acid piping, it's been rock solid.

If I would make a v2, here are the things I'd change :
- Include water temperature measurement with 18ds20
- Include weighting of chlorine and ...

Hi !

This is the function I use for this usage

function pzem_read(pzem,HC,dev_V,dev_A,dev_W,dev_CP)
--[[Read measures from a pzem in a 3Amps device
and dispatch measures for voltage, current and power in corresponding devices
Input :
pzem : type 3phase current
HC : switch "On"=night time ...

I know you excluded it explicitly, but just in case... I'm using that stuff https://www.aliexpress.com/item/3280974 ... 2e0eVhVncD for the same purpose (detecting the run of a pump), it's been working fine for years now.

Did you put 220v on the pzem while trying ? Mine does not respond without 220v

Edit : I just read again the thread on let's control it and they say the protocol have changed for pzem v3 ; my precompiled firmware won't work with those ones, sorry
