what type of boiler are u talking about? and u mean "Duty Cycle (%)=( Active Run Time / Total Time)*100"? u need a total run time on a given time period or u want to see the time it was On between a Off/On/Off cycle?
what do u want to use this for?

nobody knows how to read an O2 sensor with raspberry?

i've repaired the broken rounding function in global_data. now it works like i intended (i think)

i have a gasification wood boiler and i will like to attach an O2 sensor to it to measure the flue gases and to use the raspberry pi to control the primary and secondary air so that the burning of the wood to be the most efficient i can make it. now the primary and secondary air are set (by feeling ...

i can't make your idea work and any attempt of trying to use helpOnOff as a trigger for the scripts ended in failure. the logic is needed to making this work escapes me for the moment. nothing i've tried doesn't seems to make it go well. at some point i thought i made it work, the action was ...

sometime i need a little bit of time for the physical contacts of the relays that are controlled from domoticz to move since the physical movement is not so fast as a command on a computer. or for example i have an actuator that his motor can be moved in both ways. if it moves in 1 way and i give ...

the real switches are hidden on the normal use. i need them on the user that is allowed (me :D) to test on them, work on them, change on them, work on them, change on them, test on them ... that is why protect them with a password will be useless or a pain in the brain. can u develop a little on the ...

hello everyone. i've made myself a little script that will make 2 switches mirror each other, no matter which one i push and in what state it is, the other one will mirror. (not like the slave device for a switch). so let say i have a switch that will control some real device. i want to activate ...

i tryied to calibrate them with the help of that button.i did like this: put all the sensores together in a glass with ice and water and adjusted them all to show the same value. all great. then i remove them from the water and let them all side by side to read the room temperature and the ...

It does not work because you probably don't have execute=function(domoticz,timer) in your script but something else for example "item" instead of "timer". If you use "item" then you should also use "item.trigger". It has to match. u are right :D. is working now

You could do it the other way around: local dt = time_Of_The_Timer timer = { 'every dt minutes' } was so easy, i feel a little bit ashamed now :oops: :D for me worked: dt = 2 timer = {'every '..dt..' minutes'} and also the Kedi's version. the local dt=domoticz.utils.stringSplit(timer.trigger," ")[2 ...

english is not primary language so i'm sure the title is not suggestive and the explanation will be a struggle :D i want to take the value that i set for a timer into a variable inside the script, something like: timer = { 'every x minutes' } ... local dt = time_Of_The_Timer -- (x). i know i can do ...

did u solve your problem? if u use a 10 min trigger u will miss every 1 min that the switch is on, like previously said, so the time between On cycles will only be 9 min. if u necessarily need a 10 min cycle, here's the simplest idea i can came up with: return { on = { timer = { 'every 1 minutes ...

this is my variant of a script that will set the flow temperature depending on the exterior temperature and the inside desired temperature: -- This script will set the flow temperature of a heating system based on the external temperature and the -- internal temperature of the room.This is done with ...

i also made a PID algorithm to keep a constant temperature for who want it. return { on = { timer = { 'every 2 minutes' }, -- Triggers the script every 1 minute devices = { -- Triggers when the listed devices or variables change -- 'Auto_TempAdjustment', -- Device 'Auto_TempAdjustment' -- 'Setare ...

can someone explain how the trend is set in domoticz? after how many readings is the trend set? or is set after a time and the value of the temperature? how dose domoticz set the trend for a sensore temperature?
i have a sensore that is updated every 10 seconds and the trend is changing very slow.

none of this is helpful. this is the full picture: i have a script that run every 2 minute (or 1 min, or 3, 10 ..) to control an actuator witch move a mixing valve to keep a constant temperature when a pump switch is on and a auto-manual selector is in auto state. when i turn off one of those 2, the ...

i need to pause or sleep or delay somehow a script for 120 seconds. someone can help me telling me how to do it? i need a switch to turn on , a variable to get value 'true', then i need the script to wait for 120 seconds for the physical action to take place, then the var to take the 'false' value ...

keep in mind that u may need to modify this part for your needs and the system u have: -- Check temperature difference and perform valve adjustments if diff >= 30 then moveValveDown(valvePosition, move_down, 100) elseif diff < 30 and diff >= 20 then moveValveDown(valvePosition, move_down, 80) elseif ...

The same script to keep a constant flow temperature, a little cleaner and easier to follow and modify: return { on = { timer = { 'every 2 minutes' }, -- Triggers the script every 1 minute devices = { 'Auto_TempAdjustment', -- Device 'Selector to switch between 'Auto' and 'Manual' for the temperature ...
