Rule: If wifi not connect set gpioX 0 - possible?

[schmucke]

Hey,

thank you very much for this forum.

i need a rule which set the status off defined gpios if the WiFi Signal is lost.
I watering my garden with a Wemos D1 mini Pro -> 4 relay module -> 24V valve. I control it with Pimatic (pimatic.org) and the MQTT protocol. But, if i lost the WiFi signal i want that the ESP close all valves in the garden (Backup if i lost the signal in the time where the garden ist watering).

Is this possible by a rule?

Thank you very much,

I know this is not what you ask for but cant you make sure that the valves are closed after a certain time period (internally in the ESP Easy)? You can have the valves close after lets say 60 minutes if no "Off" command has been received from the server side?

can u explain me a sample? this is what i need.

i send a on signal remote and need, for the worst case, a backup if no off signal is coming. i think, this is a better solution if my pimatic hangs.

Use the rules and timer.

Thanks, is this possible?

Code: Select all

on givemesomewater do
   gpio,14,0  // open valve
   timerSet 1,300 // 5 minute timer
 endon

on Rules#Timer=1 do
   gpio,14,1 // close valve
   gpio,16,0 // open valve two
   timerset 2,300 
 endon

on Rules#Timer=2 do
   gpio,16,1 //close valve two
 endon
 

But, this is not what i need. I just need a Rule wich detect the remote MQTT change. When it turns the valve on, then it must start a timer which close the valve after a time if the valve is not close by MQTT.

Use MQTT Import for that.

Use MQTT Import for that.

I think, this is not this what i mean. I need a local backup. i just use a raspberry with mosquitto, but, if the system crash i want a local backup at the ESPEASY system.

If the Raspberry cannot connect to the esp to turn off the watering. I need a rule which start a timer local in this moment, where the gpio set to 1. If there come no signal (wifi loss or something), the esp must stop the watering after a specified time. i dont want that my garden is flooting by water in the worst case.

is there a rule what do the following?

Code: Select all

on gpio set to 1 do
 timerSet 1,600
 endon

on Rules#Timer=1 do
 gpio,16,0
 endon

i dont find a rule what is starting by change the gpio.

Thank you.

If you send the watering command as MQTT and fetch it through MQTT Import you can start the timer from there.

I'll try to give you an example... Hold on.

If you need this kind of local control, i think the best way is to send an event to ESP Easy from Pimatic.

The rules could then be like this:

Code: Select all

on givemesomewater do
   gpio,14,0  // open valve
   timerSet 1,300 // 5 minute timer
 endon

on Rules#Timer=1 do
   gpio,14,1 // close valve
endon

From pimatic send this to the .../cmd topic
event,givemesomewater

[Shardan]

It might be possible to use the

Code: Select all

Status <device>, <pin>

command for this too.
Did not test this myself, as far as i have seen in some forum threads this might
give strange results as it is not fully developed.

Rule using MQTT (importer)

Code: Select all

on sniff#cmdMQTT=1 do
  gpio,12,1
  timerSet,1,600 //timer 1 set for 10 minutes
  Publish %sysname%/Valve,Open
  Publish %sysname%/Status,Started watering
endon

on sniff#cmdMQTT=2 do
  timerSet,1,0 //timer 1 set to halt
  Publish %sysname%/Valve,Close
  Publish %sysname%/Status,STOP watering
endon

On Rules#Timer=1 do  
   gpio,12,0 //stop watering
endOn

Rule using HTTP (event)

Code: Select all

On startwatering do 
  gpio,12,1 //start watering 
  timerSet,1,600 //timer 1 set for 10 minutes
endon
 
On stopwatering do 
  timerSet,1,0 //timer 1 set to halt
endon
 
On Rules#Timer=1 do  
   gpio,12,0 //stop watering
endOn

Triggering through this command.

http://<espeasyip>/control?cmd=event,stopwatering

Ok, it works! But, where can i get the state of the Device?

[grovkillen]

Publish or SendToHTTP is what I would do.
