Welcome.
First you need to have enabled the Rules feature on the Tools/ Advanced page:
- Screenshot - 01_05_2021 , 16_38_07.png (10.31 KiB) Viewed 6887 times
(Tolerant last parameter is optional, both Rules checkboxes should be on)
After that you can enter a new rule in the Rules tab.
Code: Select all
on BME280#Humidity do
if %eventvalue1% <> %v1%
if %eventvalue% < 20 // A bit dry, turn humidifier on
sendtohttp,192.x.x.x,80,/cm?cmnd=Power%20ON // Turn relay on
endif
if %eventvalue1% > 30 // Humid enough, humidifier off
sendtohttp,192.x.x.x,80,/cm?cmnd=Power%20OFF // Turn relay off
endif
endif
let,1,%eventvalue1% // Save last checked value
endon
I've assumed a BME280 sensor in this example, and the 20 and 30 used are just somewhat randomly selected values.

humidity information is taken from a soil moisture sensor. I already have the active rule option, because I have another rule. I attach print screen with sensors.
Thanks for the help

Please attach files or screenshots in this forum, not on external, usually unreliable, image storage. After a while they won't be available anymore, so we can't see what was going on.
And rules can be added in a [ code ] [ /code ] tag (without the spaces, I added these so it will show here)

Sending data to Domoticz is (much) easier by using a Controller, preferably the Domoticz MQTT controller, but you will need a MQTT server too (Mosquitto is often used in combination with Domoticz). Domoticz HTTP will do fine too.

You can extend the current rule with what I posted before (cleaned it up a bit), that would then be like this:
Code: Select all
on Soil#Analog do // Values are passed via %eventvalue1%..%eventvalue4%, and %eventvalue% is an alias for %eventvalue1%
SendToHTTP,192.168.0.115,8080,/json.htm?param=udevice&type=command&idx=26&nvalue=%eventvalue1%
if %eventvalue% < 1 // A bit dry, turn water pump on
SendToHTTP,192.x.x.x,80,/cm?cmnd=Power%20ON // Turn Tasmota relay on
endif
if %eventvalue1% > 3 // Wet enough, water pump off
SendToHTTP,192.x.x.x,80,/cm?cmnd=Power%20OFF // Turn Tasmota relay off
endif
endon
NB: Each Rules set can contain multiple rules, a new rule starts with 'on <event> do', and ends with 'endon'

Hello again,
the rule made by you works very well. in this way thank you once again.
because the water pressure does not allow I would like to make 2 zones (zone 1 and zone 2) each zone controlled by a 1 relay, but not to run simultaneously. Can you help me change my rule so that
SendToHTTP, 192.x.x.ZZZ, 80, / cm? Cmnd = Power% 20ON // Turn Tasmota relay on
endif
to send the same order to another IP 192.x.x. YYY , but with a delay of 30 minutes?
Thank you,

That should be doable, just to be sure: The seconds relay should be turned on 30 min. after the first is turned on, and also off again 30 minutes after the first is turned off?
Code: Select all
on Soil#Analog do // Values are passed via %eventvalue1%..%eventvalue4%, and %eventvalue% is an alias for %eventvalue1%
SendToHTTP,192.168.0.115,8080,/json.htm?param=udevice&type=command&idx=26&nvalue=%eventvalue1%
if %eventvalue% < 1 // A bit dry, turn water pump on
SendToHTTP,192.x.x.x,80,/cm?cmnd=Power%20ON // Turn Tasmota relay on
TimerSet,1,1800 // Timer in seconds, 30m * 60 sec.
endif
if %eventvalue1% > 3 // Wet enough, water pump off
SendToHTTP,192.x.x.x,80,/cm?cmnd=Power%20OFF // Turn Tasmota relay off
TimerSet,2,1800 // Timer in seconds, 30m * 60 sec.
endif
endon
on rules#timer=1 do
SendToHTTP,192.x.x.yyy,80,/cm?cmnd=Power%20ON // Turn second Tasmota relay on
endon
on rules#timer=2 do
SendToHTTP,192.x.x.yyy,80,/cm?cmnd=Power%20OFF // Turn second Tasmota relay off
endon
Another solution could be to start the second pump after the first one stops, and run it for the same amount of time, if you need that, just ask.

Hello,
Thank you for your effort. I eventually used variant number 1. in the meantime I discovered that in "domoticz" I can make rules. I used the rule there, which I find easier.
thanks again for your help.
for the delay I used the delay option.
