These libraries look really great! I’m wondering if you’ve considered porting any for use with the Particle Photon (or Spark)?
I love the photon and the whole cloud infrastructure built around it, and it would be nice to have other integration options for smartthings.
Thanks for the quick reply. I now have the parsed message displaying on my LCD
Thanks for the feedback, Robert. I have not looked at the Photon/Spark platform. This project grew from our desire to make using the Arduino ThingShield easier for everyone. It has since grown to include LAN connected devices. My son is pondering expanding it to additional platforms (e.g. RaspberryPi, Linux, MS Windows, etc…) Mostly just concepts at this time, with no active programming currently. We’ll keep the Particle platform in mind should these efforts progress beyond the drawing board stage.
Anyone know if there is a way to change a single DS18B20 temp probe and subsequent tile to report in Celsius. I have lots working nicely in F… thanks…
Nigel,
The DS18B20 ST_Anything class does support both Fahrenheit and Celsius reporting, assuming you have only one DS18B20 attached to an Arduino pin (i.e. not daisy chained together.) In the constructor arguments within your sketch’s setup() routine, simply set the “In_C” field to “true” instead of “false”.
// For Example: st::PS_DS18B20_Temperature sensor1("temperature1", 120, 0, PIN_TEMPERATURE, true);
//
// st::PS_DS18B20_Temperature() constructor requires the following arguments
// - String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType tile name
// - long interval - REQUIRED - the polling interval in seconds
// - long offset - REQUIRED - the polling interval offset in seconds - used to prevent all polling sensors from executing at the same time
// - byte pin - REQUIRED - the Arduino Pin to be used for the One-Wire DS18B20 sensor conenction
// - bool In_C - OPTIONAL - true = Report Celsius, false = Report Farenheit (Farentheit is the default)
// - byte resolution - OPTIONAL - DS18B20 sensor resolution in bits. 9, 10, 11, or 12. Defaults to 10 for decent accuracy and performance
// - byte num_sensors - OPTIONAL - number of OneWire DS18B20 sensors attached to OneWire bus - Defaults to 1@renesis would you mind creating another project post on the community with details on what you did to accomplish this? There have been several posts over the years on integrating dumb doorbells using reed switches, vibration sensors, etc but your approach is interesting. I could never get mine to work and would be interested in learning more details about it. Suggesting a separate thread so we keep this one on topic.
Thank you in advance!
Hey @ritchierich,
I’m actually using a reed switch (wired) to trip the transistors.
I started trying to get it to just signal off the doorbell switch, but the coil in the doorbell lets too much current leak through to trigger it without adding a relay. The transistors turn on the ESP-01 to send the signal to ST which turns off again a few seconds.
Main benefit is no batteries (vs using a wireless sensor), and very little standby current.
If you (or anyone else) are still interested in the full circuit, i can certainly create a project post.
Thanks. I knew i had seen it somewhere. I have a single probe with 2 sensors connected to the same pin. Named …1 and …2 and one set to false and one to true. This gives me a C tile and F tile on my app.
@ogiewon Hello Dan! I have just started to begin trying to use your fantastic code to control an ESP-8266. I have uploaded the sketch ST_Anything_Multiples_ESP01WiFi.ino to the board and have set up the device in the SmartThings app, but I keep getting an error saying, “Child device creation failed. Please make sure that the ‘null’ is installed and published.” Any help would be appreciated. Thanks!
V There’s is a bug introduced by ST in the last month or so causing the error you’re seeing. Just delete the parent device and recreate it, remembering to configure its settings via your phone app. Afterwards, the child devices should be created.
If you manually delete a child device, the problem will return. It actually clears itself up after about 24 hours…
OR
It could be that you tried renaming the devices in the Arduino sketch. Are you starting with an unaltered version of my example sketch? Of course, you you have to edit the network section to work with your router.
Awesome Awesome Awesome, so many thanks for this project! Can’t tell you how many hours I invested into trying to get ESP8266 sensors integrated into ST!
I’m having a slight issue with adding contact sensors. When I first install this, usually neither show up. If I then add the first contact sensor, recompile and flash, then add the second, recompile and flash, I can get them added one by one. Any thoughts?

}You really shouldn’t have to add them one at a time. Maybe some sort of race condition on the ST Cloud Servers? You can always just press the REFRESH tile on the parent device. This causes all of the devices to send a status update to ST. Any missing children will be created. Also, sometimes you need to refresh the ST app to pick up the new children. On iOS, I just drag down on the device page until I see the spinning wheel icon appear, then let go. This causes the app to refresh its data.
Thanks Dan!
Another question. I noticed after I unplug my ESP8266 that my temperature data remains at the last value. I’m planning to use this device as a fridge/freezer monitor, so if my board stops working I’d rather the values go stale, rather than remain at their last value.
Any thoughts on this? Maybe some time of keep alive?
Matt,
That is how all ST devices work, unfortunately. You can very easily install a community developed SmartApp called “Device Monitor” which will notify you if any of your devices stop updating values for an extended period of time versus normal.
Check it out here. I use it and it works very well!
Thanks Dan, two more questions regarding DHT22 setup:
Can you clarify what the “120, 10” are used for in the line of code below for the DHT22?
static st::PS_TemperatureHumidity sensor2(F(“temphumid”), 120, 10, PIN_TEMPERATUREHUMIDITY, st::PS_TemperatureHumidity::DHT22)
Is it possible to setup multiple DHT22 sensors? It appears that PS_TemperatureHumidity.h automatically names the children temperture1 and humidity1. Would I have to create an additional PS_TemperatureHumidity.h for each DHT22?
On question 2 I have 5 DHT21’s in my home/outside.
You just have to define additional PINs etc… like this:
#define PIN_TEMPERATUREHUMIDITY_1 23
#define PIN_TEMPERATUREHUMIDITY_2 25
#define PIN_TEMPERATUREHUMIDITY_3 27
#define PIN_TEMPERATUREHUMIDITY_4 29
#define PIN_TEMPERATUREHUMIDITY_5 33
and then the sensors of course you are using DHT22:
static st::PS_TemperatureHumidity sensor1(F(“temphumid1”), 60, 40, PIN_TEMPERATUREHUMIDITY_1, st::PS_TemperatureHumidity::DHT21,“temperature1”,“humidity1”);
static st::PS_TemperatureHumidity sensor2(F(“temphumid2”), 60, 50, PIN_TEMPERATUREHUMIDITY_2, st::PS_TemperatureHumidity::DHT21,“temperature2”,“humidity2”);
static st::PS_TemperatureHumidity sensor3(F(“temphumid3”), 60, 50, PIN_TEMPERATUREHUMIDITY_3, st::PS_TemperatureHumidity::DHT21,“temperature3”,“humidity3”);
static st::PS_TemperatureHumidity sensor4(F(“temphumid4”), 60, 50, PIN_TEMPERATUREHUMIDITY_4, st::PS_TemperatureHumidity::DHT21,“temperature4”,“humidity4”);
static st::PS_TemperatureHumidity sensor5(F(“temphumid5”), 60, 50, PIN_TEMPERATUREHUMIDITY_5, st::PS_TemperatureHumidity::DHT21,“temperature5”,“humidity5”);
Finally don’t forget the addSensor section:
st::Everything::addSensor(&sensor1);
st::Everything::addSensor(&sensor2);
st::Everything::addSensor(&sensor3);
st::Everything::addSensor(&sensor4);
st::Everything::addSensor(&sensor5);
The child objects are created in the main sensor list and you can rename them to whatever you want them called with settings for each child object.
Thanks David. Do you know what the “60, 50” nomenclature is for?
At the top of each device’s class .h and .cpp file you will find a detailed explanation of what each of the arguments is used for. The comments/documentation for the DHT Temperature & Humidity sensors is below.
So, the “60, 50” nomenclature means that the device will be scanned every 60 seconds, with a “50” second offset from the top of a 60 second window of time.
For multiple sensors, I would probably go with 120 seconds for the poling interval. For the offset, I would set the first one to be 5 seconds, the second one to be 10 seconds, and so on (i.e. 5, 10, 15, 20, 25, 30, etc…). This prevents trying to collect and transfer all the data at once. It also provides a more balanced workload for the ST cloud to handle. No reason to slam it all at once.
// Create an instance of this class in your sketch's global variable section
// For Example: st::PS_TemperatureHumidity sensor2("temphumid1", 120, 7, PIN_TEMPERATUREHUMIDITY, st::PS_TemperatureHumidity::DHT22, "temperature1", "humidity1", false);
//
// st::PS_TemperatureHumidity() constructor requires the following arguments

// - String strHumid - OPTIONAL - name of humidity sensor to send to ST Cloud (defaults to "humidity")
// - bool In_C - OPTIONAL - true = Report Celsius, false = Report Farenheit (Farentheit is the default)hi, thank you for this code. My project is to control my garage by wiring my garage remote to a relay (my garage opener has a fancy control panel that I can’t simply wire the relay into). I previously tried using a raspberry pi with webiopi, but that was very flaky. Your code, along with the ESP8266-12e works very well.
I have a problem, though. The relay seems to engage for approximately 10 or more seconds no matter what I set the onTime and offTime to when calling the relaySwitch constructor. I even changed the value in the relayswitch.h header file with no effect.
Please note that my relay board is a normally on type so I set the reverse logic variable to true when calling the constructor. Also, I only have two relays connected at this time, nothing else.
#define PIN_TIMEDRELAY_1 D5 //SmartThings Capability "Relay Switch"
#define PIN_TIMEDRELAY_2 D6 //SmartThings Capability "Relay Switch"
static st::S_TimedRelay sensor1(F("relaySwitch1"), PIN_TIMEDRELAY_1, LOW, true, 1, 1, 1);
static st::S_TimedRelay sensor2(F("relaySwitch2"), PIN_TIMEDRELAY_2, LOW, true, 1, 1, 1);Happy to try to help troubleshooting. Can you please post your entire sketch either here, or in a private message? That will help me to debug your actual code.
I have never seen the TimedRelay device not work as designed. The only thing that I can think which would mess up the timing is if there was a lot of extra code added to you loop() function in the sketch. Any delays or looping code inside of loop() will screw up all of the timing.
