How to control pool heater with Wireless Thermostat

[barkster]

I have a thermocouple that I soldered to back of wireless thermostat and it works great but how can I turn on the pool heater when the temperature is below set point?  I thought it was the Heat CTL node but mine shows nothing for status

[stusviews]

If the thermostat is calling for neither heat nor cooling, then there will be no status showing.

ah

Can someone check my programming, when pool heating variable is set to 1 I want to set thermostat to 89 degrees and turn on pump.  If set temp below temperature then turns on heater.  Every 45 mins I was to run the pump to cycle pool water and get good temperature reading.  The circulation program doesn't seem to be working for me, the pump has been running the whole time.

The first two programs, Heat Pool and Heat Spa, have no trigger. I don't see anything that runs those programs.

[barkster]

I'm using those to turn on with alexa

[barkster]

I'm finding when the thermostat turns heat off it is not turning off the heater, how reliable is "Heat Ctl" and am I using it correctly.  Its like when that changes its not kicking anything off because when it should have been off I right click and chose "run if" and it turned off as it should

 

If
$PoolHeating is 1
And Control '1F.11.34 - Heat Ctl' is switched On

Then
Set 'Pool Equipment / SpaValve' Off
Set 'Pool Equipment / Polaris' Off
Wait 1 minute
Set 'Pool Equipment / FilterPump' On
Set 'Pool Equipment / PoolHeater' On

Else
Set 'Pool Equipment / FilterPump' Off
Set 'Pool Equipment / PoolHeater' Off
Set 'Pool Equipment / Polaris' Off

 

Reading the log it says it turned the thermostat "off" but it is not off when I look at it

[stusviews]

There is nothing in the condition statement that indicates what to do when Heat Ctl is turned off. Else will never run.

 

Add

 

And Control '1F.11.34 - Heat Ctl' is not switched Off

 

to enable Else

[barkster]

yeah that's what I don't get, if Heat Ctl' is switched On and Heating  = 1 are both true then it turn on else it turn off.  I thought that if the if statement wasn't true else always fired.  I mean when I write in c# that's how it works.  Please explain, does it have to do with it being control?

You have a repeat statement line with no code to repeat underneath it.

 

You've been out to C too long

 

The construct works like this.

 

 

Repeat every 45 minutes

...do this

...do that

Repeat 1 time

....do something

....do something else

What you expect is an extremely common logic misconception. For example, suppose I say that if the sun shines, I'll go the to beach. The sun shines and I do go to the beach, then my statement is obviously true. Now consider that the sun doesn't shine and I do go to the beach. Is my statement true or false?

 

My statement is still true. Why? Because I only indicated what I'll do if the sun shines. I did not say anything about what I'd do if the sun does not shine. It doesn't matter in that case if I go to the beach or not. My original statement is false only if the sun shines and I don't go to the beach. What I do if the sun doesn't shine does not affect the truth of the original statement.

 

Your statement, And Control '1F.11.34 - Heat Ctl' is switched On, only instructs what to do when the device is switched On. There is no mention of what to do if the device is not switched on. That's why you need to include a statement about the device not being switched on.
