Watermeter through GPIO and TCRT5000

[sincze]

Can someone write me a step guide to install, Isrcounter.
My script for water is working only i want to make it more accurate

It was a bit hidden I have to agree

I attached the tcrt through espeasy to domoticz. I experience a weird consistenr ~6% higher reading in domoticz than the real consumption. Consistent enough to make me wonder if it's really the reflection meter edge that could cause it. Any thoughts?

Did you connect directly to EspEasy or also used a resistor (pull down).
I know that having this sensor exposed to external light (lightning) will increase the usage as well.
So I covered mine. I am not using the Espeasy though and have been running the tcrt5000 for 2 years now.
It works like a Swiss clock.

Turned out that the esp module was faulty and generated lots of bogus counts. Probably a broken lead somewhere which was really difficult to track down.

commandArray = {}

print('> Monitoring water consumption')

-- Water usage
-- Retrieve value from water meter device:
sWaterUsage = otherdevices_svalues['Water']

-- To have a better readable format, divide number by 1000:
sWaterUsagePrint = tonumber(sWaterUsage / 1000);

-- calculation is done with the unmodified water value
sWaterUsage = tonumber(sWaterUsage);

print(">> Utilities: Water usage until now is " .. sWaterUsagePrint .. " ");

if (devicechanged['GPIO_WATER'] == 'Close')
then
sWaterUsageTot = (sWaterUsage + 1)

print(">> Utilities: Water usage is now " .. sWaterUsageTot .. " ");
commandArray['UpdateDevice'] = '164|0|'..sWaterUsageTot..''
end

return commandArray

I changed the code in red. This function is designed for it. When using a test and production environment you don't need to update the IP address.
