OK,
I have a sauna unit that is not connected to the house but in my garden.
The infrared sauna has a control panel and control box.
To switch on the sauna I have to push a momentary power button once.
One push is on and other push is off.
Then I have to push two other momentary buttons to switch on two rows of lamps at full power.
Those switches can not be pushed at once!
I like to know when the sauna is at a certain setpoint and send an email or tweet or what ever you like to use
once only.
I hacked the control panel and found the connections for the 3 seperate switches.
I made a debug version with a ESP201 to control three relays to perform the push button actions with delay of one second each and remote control works fine by using the following ESPEasy output options.
Short pulses from
http://www.esp8266.nu/index.php/GPIO
To send a pulse to a certain pin:
http://<ESP IP address>/control?cmd=Pulse,<pin>,<state>,<duration>
Example to send an active high pulse on GPIO 2 for 500 mSeconds:
http://<ESP IP address>/control?cmd=Pulse,2,1,500
There is no return signal YET but there are leds in the control panel which light up when each function is activated.
So I might use three opto couplers to measure the LED outputs and feed these into the ESP201 to know their EXACT status too in DMZ.
Now in DMZ "virtual sensors" have NO WORKING notification function.
This idea was proposed by Martinus and I had to give it a try in code form as a simple work around.
So in in a lua script or blocky you might get a work around.
First make in DMZ setup, more options, user variables a integer variable of your choice.
In this example I used "saunatempok" and set it to 0 as standard value..........sauna_temp_ok would have been a better description...
Further I have a button called "Sauna aan" which is an virtual ON/OFF button which switch on two relays by .
I made also a virtual thermostat setpoint called "Thermostaat sauna". Hacked off in the right handside of the picture.
and finaly we have the ESP EASY or EASY ESP DS18B20 sensor that in DMZ is a virtual temperature sensor "Temp sauna".
Now we set "Sauna aan = 1" (sauna = switched on) and my sauna heaters are switched on.
We only get an email confirmation if we meet certain values which are fitted in the AND function.
So the function just waits if the sauna temp passed the thermostat set point.
As the variable is zero and all other functiosn are valid we send an email that we have reach the desired temp.
Together with sending the email we set the variable to 1 which prevents a resend of the email as the function is not valid anymore.
As soon as we switch off the sauna by "Sauna aan = 0" we also reset the variable for a next session.
EDIT: in the blocky I had to change "Sauna aan = 0" to "Sauna aan = ON" or "Sauna aan = OFF"
Normally in programming 0 = OFF and 1 = ON but in this Blocky it is not.
After the change the fucntion is working fine.
