PH and Temp controller

Re: PH and Temp controller with arduino

Hi everyone... couple of months ago i started working on a PH controller and temp controller. I finally got it working including in Pimatic.

You can find the whole how-to, part-list and combined sketch in here.

PH and Temp controller for Pimatic with mysensors (how-to)

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@Knightan I believe that your problem may be related to this block of code. See my thoughts as comments.... if (message.type == V_STATUS) { //This is true for all messages received // Change relay state state_1 = message.getBool(); //This sets state for state_1 to the received value. digitalWrite(LED_PIN_Channel_1, state_1?RELAY_1_ON:RELAY_1_OFF); // Store state in eeprom saveState(CHILD_ID_5, state_1); // Write some debug info Serial.print("Incoming change for sensor: STATE 1"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } if (message.type == V_STATUS) { // Change relay state state_2 = message.getBool(); //This sets state for state_2 to the received value. digitalWrite(LED_PIN_Channel_2, state_2?RELAY_2_ON:RELAY_2_OFF); // Store state in eeprom saveState(CHILD_ID_6, state_2); // Write some debug info Serial.print("Incoming change for sensor: STATE 2"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } It seems to me that state_1 = message.getBool(); AND state_2 = message.getBool(). So they both get set to the incoming value. I think you need to not set both to the same value and instead differentiate them to unique values. I could be wrong as I have not had chance to do anything related to mysensors for a long time now - I also don't use Domoticz. Have a look at the code on this page, it might help you a lot.... https://www.mysensors.org/build/relay

I think the comments you make are good. I do have a question about the removing the regulator. I assume you mean the 5V to 3.3V regulator. I connect to the 5V and I see lot of variation in moisture readings due to the variation in the output of the power supply (solar panel/stepdown). I have a calibration routine for that. The voltage can go as high as 4.2V, which I believe may be bad if I connect the power supply to 3.3V. Of course, this is not a concern if using two 1.5V batteries. With batteries, the moisture reading would be more consistent over a day. Lot of advantages there. I just don't like changing batteries and I really hate it when they leak. I have every reason to believe that my power supply will last 10 years and I am fortunate to live in a place with consistent sunshine . Someone replicating my project will have to take this into consideration. My design easily accommodates a different power supply. And my power supply could be used in other projects. Resistive vs Capacitive sensor. I'm glad you report good results. This gives people options. Water moisture: I've had good experience with "spraying" the Arduino with clear electronic coating and sealing the enclosure with liquid tape. -OSD

@OldSurferDude I use this. https://www.homedepot.com/p/Orbit-Solenoid-for-Battery-Operated-Timer-57861/203151515 Instead of having to hold the valve open, i can just pulse it. I use a simple motor controller to pulse it and when i need to close it, pulse it in "reverse". That way I could use a battery and if it only opens once or twice a day it's only a half a second or so of draw off the battery.

That is a well documented project. Much appreciated
