Best controller for HVAC control ?

frishrash last edited by

Hi all
I'm looking for a controller that allows controlling HVAC and showing/responding to soil moisture levels.

For HVAC, I have Arduino device capable of sending the right IR codes for my HVAC.
I'd like the controller to have an interface allowing me to power on/off, set mode (heat/cool/dehumid/...), control fan speed, target temperature, flaps, sleep mode, ionizer.

For soil moisture level, simple reading should suffice, however it should support multiple moist sensors connected to a single Arduino device.

Any suggestions for most suitable controller ? ideally with built-in user interface that supports the level of HVAC control I want out of the box

Thanks!

So, now I replay with 255:255:3;0;4;1 instead of 255;255;3;0;4;0 and when I get the request 1;10;2;0;3;1.4.1 Yes I think node-id 0 should not be used.

@Vladut-Grecu said: That remote had a wireless thingy.. W Indeed it was RF based remote control, but it was for X10 protocol and it wasn't compatible with my existing system. There's somewhat painful way to hook x10 to Vera via Raspberry running Mochad driver, but I'm getting rid of x10 altogether.

Here is the sketch if anyone can help out. #include <SPI.h> #include <MySensor.h> #define CHILD_ID_LIGHT 0 #define LIGHT_SENSOR_ANALOG_PIN 1 #define NODE_ID 9 int BATTERY_SENSE_PIN = A2; // select the input pin for the battery sense point unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) MySensor gw; MyMessage msg(CHILD_ID_LIGHT, V_LIGHT_LEVEL); int lastLightLevel; int oldBatteryPcnt = 0; void setup() { // use the 1.1 V internal reference //analogReference(INTERNAL); gw.begin(NULL, NODE_ID, false); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Soil_Moist_Sensor_grb", "1.15"); // Register all sensors to gateway (they will be created as child devices) gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL); } void loop() { int lightLevel = (1023-analogRead(LIGHT_SENSOR_ANALOG_PIN))/10.23; Serial.println(lightLevel); if (lightLevel != lastLightLevel) { gw.send(msg.set(lightLevel)); lastLightLevel = lightLevel; } // get the battery Voltage int sensorValue = analogRead(BATTERY_SENSE_PIN); Serial.println(sensorValue); // 1M, 470K divider across battery and using internal ADC ref of 1.1V // Sense point is bypassed with 0.1 uF cap to reduce noise at that point // ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts // 3.44/1023 = Volts per bit = 0.003363075 - changed without ref volt float batteryV = sensorValue * 0.00305734; int batteryPcnt = sensorValue / 10; Serial.print("Battery Voltage: "); Serial.print(batteryV); Serial.println(" V"); Serial.print("Battery percent: "); Serial.print(batteryPcnt); Serial.println(" %"); if (oldBatteryPcnt != batteryPcnt) { // Power up radio after sleep gw.sendBatteryLevel(batteryPcnt); oldBatteryPcnt = batteryPcnt; } gw.sleep(SLEEP_TIME); }

Do some debug on the node and on gateway and check if data is actually sent from the node and received by gateway. Also use wait instead of sleep if you are using it as a repeater and relay actuator.

@dzairo Can't help you with the project as it's way over my pay grade, but it sounds interesting. Good Luck!

Automatic node ID's are now also supported! There is a step-by-step install guide here: https://github.com/tsathishkumar/MySController-rs/issues/30 You can easily run this alongside Domoticz. Burn an image for the Mozilla Gateway onto an SD card. Follow the guide above to install MySController-rs. Install Domoticz at port 8081 and 444 (instead of 8080 and 443, as the Mozilla Gateway is already at those ports).
