Re: Domoticz 17592 . Waterflow devices not triggered if flow = 0
Posted: Saturday 04 April 2026 22:51
OK thanks, I will see what I can do to turn around this bug. But for me, if it's not a bug, it's a bad regression.
i used to use espeasy also for a watermeter.
at first i tried to calculate the flow also until i found out that the pulscounter not only counts pulses, total but also time.
this time can be used to represent the flow/minute
this is the script i used but of course i do not know anymore which devices i specified(besides the pulsecounter).
it also collects the total value again in case there was an outage and the esp was reset.
i did this by initiating a mqtt broadcast so domoticz sends out the total through mqtt which is collected by espeasy
I migrated everything to a new watermeter using esphome.
that one is way better than the one i used with espeasy since it sends out everything over MQTT so no more dummy devices.
Code: Select all
on Pulsecounter#Count=1 do // When Pulse is detected
if [Watermeter#Total] != 0 // and watermeter was not reset
TaskValueSet 3,2,60000/[Pulsecounter#Time] // set Water#Flow
timerSet,1,16
TaskValueSet 3,1,[Pulsecounter#Total]

if [Watermeter#Flow] > [Watermeter#MaxFlow]
TaskValueSet 3,3,[Watermeter#Flow] // copy Flow to MaxFlow
