Controlling boiler from valve position

Setup, Configuration and Use Beginners
1

How would a script or rule look like, if I want the Switch to be off, when all values/numbers are 0, and on when its between 1 and 100?

You can put all the items in a group and use persistence with a rule.

Example:

rule "persistOnEveryChange"
when
  Member of persistOnEveryChange changed
then
  if(triggeringItem.state > 0) {
    triggeringItem.persist
  }
end

Just need to add your switch to be on/off depending on the results.

Great thx, and where do I throw in the On Off thingie

rule "Boiler Start/Stop"
when
  Member of HeaterValve changed
then
  if(BoilerAndCirculation.state > 0) {
    BoilerAndCirculation.persist
  }
end
4 
rule "Boiler Start/Stop"
when
  Member of HeaterValve changed
then
  if(BoilerAndCirculation.state > 0) {
    BoilerAndCirculation.persist
    YourSwitch.sendCommand(ON)
  }
else {
    YourSwitch.sendCommand(OFF)
}
end

I think you will need to use if(triggeringItem.state > 0) and not BoilerAndCirculation.state as this is a switch item not a number.

Maybe like this:

rule "persistOnEveryChange"
when
  Member of persistOnEveryChange changed
then
  if(triggeringItem.state > 0) {
    triggeringItem.persist
    BoilerAndCirculation.sendCommand(ON)
  }
else {
   BoilerAndCirculation.sendCommand(OFF)
}
end
5

Im pretty sure im close, but the switch doesnt trip, only manually in OH Controlpanel, and when I mouseover the group in the rule in visual I get all the states for the group etc…

rule "Boiler Start/Stop"
when
  Member of HeaterValveGroup changed
then
  if(HeaterValveGroup.state > 0) {
    HeaterValveGroup.persist
    BoilerAndCirculation.sendCommand(ON)
  }
else {
   BoilerAndCirculation.sendCommand(OFF)
}
end
6

What do you see in the logs when the rule runs? Open frontail log in a browser if you have frontail.

This is what I got in the log, it only sends OFF

Try this:

rule "Boiler Start/Stop"
when
  Member of HeaterValveGroup changed
then
  if(HeaterValveGroup.state > 0) {
    HeaterValveGroup.persist
    BoilerAndCirculation.sendCommand(ON)
  }
else if (HeaterValveGroup.state <= 0){
   BoilerAndCirculation.sendCommand(OFF)
}
end

Nope, Im thinking, could it be a problem for the Rule, if some valves are 0 and some lets say 80? all valves are independent, and when the shines, all valves upstairs are 0 but basement still 18 or so…
Make sence?

10

Yes, as the rule is checking for all to be at or equal to 0. You may need to split the rule and groups, one for upstairs and one for downstairs if that will work for what you need.

You will need circulation if the valves are open correct?

11

if I stop using group but the items, can i just some kind of if,if,if,if,if,if = then?

12

That would work, but it all depends on if you need circulation when a valve is open, assuming the switch controls the pump. You would also need to know the correct value of each valve that is not 0 for when you want the switch off.

13

The switch just tells the OpenTherm protocol, to make the boiler stop circulating water to the radiators, only hotwater is then maintained :slight_smile:

So the mission is, if any of the Radiator Valves are open, the boiler should kick in, and offcource if all are closed, then kill the boiler…

14

Forgive me if I do not understand, I live in the South part of U.S. so boilers are rare, if any valve is open the boiler should kick in correct?

15

Yes

16

Try removing HeaterValveGroup.persist part from the rule and see if it changes.

17

Hmm its still very stuborn sending the OFF command when theres a Valve change in either direction

18

It may be the trigger and using groups,:thinking: change it to:
when
Member of HeaterValveGroup received update
then

EDIT: How do you have the Group defined, e.g. Group:Number, Group:Number:AVG, etc…?

Since all need to be Zero I think using average would work.

Change group to:

Group:Number:AVG   HeaterValveGroup       "Radiator Ventil Position"        (HeaterValveGroup)

I gotta few things to take care of, best of luck, will check in later. Here’s a link to group info if using AVG didn’t work out.
