    • RE: BBQ Temp Controller - Any Interest?

      @wergeld said:

      I have been working on this idea as well. My issue was finding probes that would survive the higher temps and run off a minimal power supply (batteries) - while still being cheap. It is the last item that has prevented me from moving forward. At the prices I have seen for temp probe/IC it is actually cheaper just to get a store bought meat thermometer with a remote display that is locked in. I suppose one could figure out their transmission protocol and port it to some radio receiver to an arduino. I have not even looked at making the grill react to inputs yet but I like that idea.

      To me, this part is what sets this idea apart from others. For example, if you see that your food is cooking too fast, you could remotely turn down your cook temperature to slow it down a bit. Or you could script your controller to adjust the cooking temperature at a certain time or after a particular condition is met.

    • RE: BBQ Temp Controller - Any Interest?

      So here's my initial attempt at putting something together. Fair disclaimer, this was done while staying up all night doing a cook after being awake all day. I think it probably has a good overall structure of what needs to be done, but the content can be improved in almost every area.

      EggCooker20160618.ino

      I see a couple things needing to happen:

      • Get reading from multiple probes
      • Send readings to controller via MySensors formatting
      • Get setting from controller via MySensors API for grill temperature setpoint.
      • Use grill probe reading and grill temp setpoint with PID controller library to control fan

      Hopefully this will get some discussion started. Any inputs on the best way to tackle this?

      Also, how about a good name for this project?

    • RE: BBQ Temp Controller - Any Interest?

      I believe I purchased my probes from AuberIns.com. I see that they have a PID controller that can be used to control the grill temp, and it's fairly priced. What it doesn't do is give you a way to remotely monitor or set parameters, and it only has one probe to measure the grill temp.

      What they do offer is a pre-configured blower with adapters for several different types of smokers. Buying one of these may be better than trying to fab your own.

    • RE: BBQ Temp Controller - Any Interest?

      @hek - glad to see some interest. I'll let this post settle for a couple days and see how much interest there is. I purchased all the components (probes, fan, etc.) some time ago, and never got around to finishing this project.

      One thing I've learned about smoking over the years is consistency in temperature is the key. I started with a home built offset cooker that was near impossible to control. I then built a Stumps-style smoker after seeing them. That was way too big to be practical, so I moved on to a Big Green Egg, which I love.

      Back on topic...I really hope we can get this going.

    • BBQ Temp Controller - Any Interest?

      Re: BBQ Temp Controller Build

      Although my time is very limited, I'd really like to get some more interest in this project and get some working code up for others to contribute to.

      Background: I enjoy smoking different types of meat on my smoker, however it is always a challenge as some cooks can go as long as 12+ hours. When you expect to have guests over mid-afternoon, it means a really long night of monitoring and making minor adjustments to ensure temperatures stay where they should on both the smoker and the meat being cooked.

      Goal: To build a temperature control system for charcoal/wood burning smokers that allows monitoring of the grill temperature as well as 1-2 probes for the internal temperature of the item(s) being cooked. It should be able to be integrated into a controller such as OpenHAB easily using the mysensors API. It should also have the capability to control a small fan which blows into the firebox of the smoker to increase the cooking temperature to a specified value. There are commercial versions of these, but if we are building home automation sensors and switches with arduinos, why stop there? Commercial versions can be found here or here.

      Any takers to help develop this for others to use? I'm far from the best coder, but would love to get some help putting a working package together for others to use. My time is scarce these days, which is the main reason I keep putting off this project. If you're willing to contribute in some way, let me know and I'll post up my progress on the code and we can divide and conquer.

      If there's no interest, I'll keep it on my project list and eventually try to work it out myself.

    • RE: Sending I_CONFIG to set unit of measure on sensor nodes

      Eventually, the repeated requests seem to calm down and it works as expected. What I'm trying to figure out is why the repeated messages occur.

      If I'm reading the code correctly, the only time the 'if(subType == I_CONFIG)' should be invoked is when the request for config units is made from the sensor node. I've confirmed that the sensor node only requests the I_CONFIG units once, and the gateway only receives it once. I can't seem to make sense out of why the gateway replies so many times...

    • RE: Sending I_CONFIG to set unit of measure on sensor nodes

      It seems as if the problem I'm seeing is more with the controller/gateway than with the node. The gateway is sending out the I_CONFIG units repeatedly (like hundreds of times). The node is only requesting the units once.

      That is why I'm not sure if it is a gateway problem or a controller (rules) problem. I can comment out the following section:

      if(subType == I_CONFIG){
      println("Request config units") 
      sendCommand(Arduino, nodeId + ";" + childId + ";" + msgType + ";" + ack + ";" + subType + ";" + core_Units.state + "\n")
      println("Sent measurement units:" + core_Units.state )
      }
      

      and the sensor node is no longer flooded with responses after it asks for config units. I'm just not sure why this is "flooding" the sensor node with responses.

    • Sending I_CONFIG to set unit of measure on sensor nodes

      I tried asking this on the OpenHAB forums, but I haven't received any feedback. I'm having problems properly sending the I_CONFIG value to my sensors.

      Below is my "Arduino sends to Openhab" rule that I've added the I_CONFIG variable to:

      rule "Arduino sends to Openhab"
      when
      Item Arduino received update
      then
      var String lineBuffer = Arduino.state.toString.split("\n")
      for (String line : lineBuffer) {
      var String[] message = line.split(";")
      var Integer nodeId = new Integer(message.get(0))
      var Integer childId = new Integer(message.get(1))
      var Integer msgType = new Integer(message.get(2))
      var Integer ack = new Integer(message.get(3))
      var Integer subType = new Integer(message.get(4))
      var String msg = message.get(5)
      if(msgType == 1 ){
      if (subType == V_TEMP){ 
      postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), msg)
      println ("Temp item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " temp: " + msg )
      }
      if (subType == V_HUM){
      postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), msg)
      println ("Hum item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " hum: " + msg )
      }
      }
      if(msgType == 3){
      if(subType == I_BATTERY_LEVEL){
      postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), msg)
      println ("Battery level received: " + msg)
      }
      if(subType == I_CONFIG){
      println("Request config units") 
      sendCommand(Arduino, nodeId + ";" + childId + ";" + msgType + ";" + ack + ";" + subType + ";" + core_Units.state + "\n")
      println("Sent measurement units:" + core_Units.state )
      }
      if(subType == I_SKETCH_NAME){
      println("Sketch name: " + msg )
      sketchName=msg
      }
      if(subType == I_SKETCH_VERSION){
      println("Sketch version: " + msg )
      postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), sketchName+" " +msg )
      sketchName=""
      }
      }
      }
      
      end
      

      In it's current state, the sensor node gets repeated responses from the controller/gateway with the units (I or M), based on the value of the item Core_Units.state. I'm trying to figure out why this doesn't just sendCommand one time to the sensor node. The response received by the sensor node seems correct, I just get hundreds of them. Below is the output from my sensor node after requesting the I_CONFIG value from the controller:

      read: 0-0-105 s=255,c=3,t=6,pt=0,l=1,sg=0:I
      

      This appears correct to me. Any thoughts?

    • RE: Low Power Servo Actuator

      Thanks for that info. I'm sure I'm not the first that has thought of it, but I wonder if it would be possible to have the remote actuator "poll" the controller for a status and wait for a response? There would be a delay, but maybe there could be a compromise between battery life and lag in commands being carried out by the actuator.

      I haven't looked, but maybe someone has tried this already...

    • Low Power Servo Actuator

      I have been planning a build for a blind controller along with my openHAB/Arduino serial gateway. I currently have things running the the bench with a USB powered Uno. I was under the impression that this could potentially be accomplished using battery power on a pro mini.

      I just read this post, and now I'm second guessing that this can be done. My plan was to power the arduino with 2AA batteries, and power the servo with 4 AA batteries.

      Am I understanding correctly that having the remote actuator "listening" for commands from my serial gateway will consume batteries quickly? If so, is there any way around this?

    • OpenHAB setup

      As a disclaimer, I'm not a programmer by any means, but I'm learning. I have OpenHAB setup and working and haven't touched the setup in about a year. I'm using MySensors with two sensor nodes currently. They are both powered (not battery) and only capturing temp and humidity values and sending to my serial gateway via NF radios.

      Hardware is currently RPi and Arduino UNO GW, and Nano sensors. I would like to expand my setup and include some additional sensors. I'd like advice on moving forward.

      1. I had problems getting the sensors working initially. I had to set the Node ID's manually, which I believe is a limitation of OpenHAB. I also could not for the life of me get the measurement units to work in °F. I had to somehow manually set each node to send in °F as opposed to °C. I would like to have this work correctly if possible from the get-go.

      2. I would like to battery power my arduino sensors. I plan to replace my current hardware with Arduino Pro Mini 3v (8MHz) with the low power mods done. The gateway will likely be run on a Nano instead of the UNO. My current goal is to have four types of sensors: (1) Temp/Humidity, (2) Servo - Blinds, (3) Door, (4) Light Level. I hope to have these all be able to run for an extended period of time on battery power only. The servo for blinds will probably be the most difficult to do this, however I have some ideas.

      3. I would also like to be able to integrate other wireless technologies. I currently have an Aeon Labs Z-Stick 2 for Z-Wave devices (although I don't have any Z-Wave devices to test/use currently), and I have my eyes on a couple Zigbee devices that I would like to be able to incorporate. What is the best way to do this?

      Any advice on how to move forward would be appreciated. It looks like there isn't a whole lot of activity in this forum, but many people who are using OpenHAB with MySensors. I'd love to get feedback before re-inventing something that is already done.

    • RE: set Metric on gw?

      Glad you got yours working. I tried changing the code on mine to see if it would respond, but it didn't. I may have hard coded the sensors to imperial though. I believe mine is catching the I_CONFIG variable, because I would get an output on the console when the sensor started up where I had a println command. Hopefully it was just my syntax that was wrong.

      On another note, can you trigger a "sendCommand" with xxx;255;3;0;6;<I or M> at any time, or can it only be in response to the request from the sensor node?

    • RE: set Metric on gw?

      I was able to see the request come into the gw on mine, however I'm not sure how the reply should be structured given the sensor node is 101.

      @Chester good point, but I was restarting the arduino and still couldn't get this to work correctly. Also, the missing "end" was just missed out of the paste here, it was in my code.

    • RE: Sending serial commands to sensors

      @Jan-Gatzke I'm not sure that I understand what you mean. Maybe you're referring to the + after status? If so, I think you may be right, but I would assume that will only affect what is printed in the console, and not what is sent to the remote sensor. In the example above, I believe that 101;255;3;0;6;I\n would be sent if the switch was on, and 101;255;3;0;6;M\n would be sent if the switch was off.

      I believe that most of my problem is trying to figure out what should be sent to the remote sensor to enable this. In the above case, my remote sensor is ID 101. Ideally, I'd like to send the message to all sensors, and not just a certain node ID. Would that be 255;255;3;0;6;I\n?

      At one point, I thought I had this working, but it wasn't repeatable.

    • RE: BBQ Temp Controller Build

      @5546dug That's an interesting build. I've come across several using a PID controller similar to that, however they have mostly been on electric smokers. My original intent was to do a PWM fan that could be speed controlled, but it was very hard (impossible) for me to find a blower type fan that was PWM-capable. My very initial testing showed that an on/off model would work as well but I haven't tried this on the Big Green Egg yet.

      My main concern is being able to feed a temp from my phone back to the arduino controlling this, and being reliable if for some reason wireless connectivity was lost from the arduino. I don't think this should be too hard, but will probably take some trial and error on my part.

    • RE: BBQ Temp Controller Build

      @BulldogLowell
      That looks like an interesting project as well. This originally started very similar to that one, and I was planning on using a local LCD on it for the display. I quickly realized that the local LCD would not give me the "warm fuzzy" that checking this remotely would give me. When I started going towards a web interface design, I then realized that I really didn't need the local LCD at all.

      I'm not at all good with the programming piece, but I've gotten by so far. We'll see how this works out.

    • BBQ Temp Controller Build

      I'm in the process of building a BBQ temp controller, and was trying to figure out the best way to remotely monitor/control it. After coming across this website a month or so ago, I'm now running OpenHAB on a RPi2 and have a couple temp sensors deployed around my house.

      This project is a little more involved, and I'm sure I'm going to run into roadblocks along the way. My goal is to have a sitemap in OpenHAB that will allow me to set and monitor my desired grill temp, which will control a small fan on my BBQ using a PID algorithm, as well as display the temps of the meat probes so I can know how things are going.

      I currently have the sitemap setup in OpenHAB, and have had the code working for the thermocouple temp probes that I will be using for the grill and meat temps. Today I will start trying to get the two to work together, based on the MySensors Serial API. I'll be using the NRF24L01+ radio modules for this. I'll post my code periodically, and hopefully will have some chime in on how to make it work or improve it.

    • RE: Sending serial commands to sensors

      I'm making slow progress on this however I'm still running into a wall. I have the following rule setup:

      rule "Test Rule"
      when
      		Item Units received update
      then
      		var String status
      		if(Units.state == ON)
      			status = "I"
      		else
      			status = "M"
      		sendCommand(Arduino, "101;255;3;0;6;" + status + "\n")
      		println("Updated Sensor Units to " + status +)
      

      I'm attempting to tell the serial monitor to report the temperature in imperial units (Fahrenheit) as opposed to the default metric units (Celsius). The rule seems to be running successfully, but I'm getting the following error:

      2015-05-12 16:57:52.733 [ERROR] [o.o.c.s.ScriptExecutionThread ] - Error during the execution of rule 'Test Rule': Index: 1, Size: 1
      

      I can't seem to find any reference to this error. I don't see anything on the serial monitor of the arduino nano after flipping the switch on my sitemap when using the humidity sketch from the mysensors main site.

    • Sending serial commands to sensors

      I'm having trouble sending serial commands from openhab to my sensor nodes. The first thing I'm attempting is to change the units on the my sensors humidity sketch from Celsius to Fahrenheit. I wrote a crude rule that seemed to be successfully sent to the arduino, but I saw nothing on the serial monitor of the arduino sensor and saw no changes in the temperatures reported. How can I further troubleshoot this?

    • RE: Tweaking sensor configs

      So I still haven't quite figured this out. There doesn't seem to be any information out there on this feature, at least not that I can find. I believe I've successfully transmitted "101;255;3;0;6;I\n" from my gateway, which from what I understand should set the sensor node to Imperial units. While watching the serial monitor on the sensor node, I did not see anything received and the units did not change. There is a possibility that my code did not transmit that code successfully, however the rule associated with the command was triggered successfully and I'm not sure of any way to verify.

      I know what I could easily modify the code on the sensor node to change the units, however I like the idea of being able to control multiple sensor nodes centrally. I also like the fact that the sensor code was written to include this functionality, and I'd like to take advantage of the well written code published by mysensors...

      Any help would be greatly appreciated.

      1. My temperatures are showing in Celsius instead of Fahrenheit.

      I know that I could go hack up the arduino sensor code to have it display in either, but I can see that it is incorporated into the sensor code to determine if the controller is configured for Celsius or Fahrenheit. I also see in the serial protocol that there is an internal message type for configs (I_CONFIG) that is used for sending either metric or imperial unit of measurement. I have a very vague understanding of the rules on the openhab end, however I think it is a mapping that needs to happen there. Confirmation and any examples would be great. I would also like to poll other things such as battery life, etc, so understanding this would be great.

      1. How do you push data TO the sensor node?

      I have two projects lined up right now that would require both pushing data to and receiving data from a sensor node. Is this also in the rules configuration on openHAB that the mappings/instructions would be configured? Anyone have examples they could share?

    • RE: [Tutorial] openHAB with serial gateway

      Thanks @TimO. I got everything running in /opt (@9600, but I can change that later), and am receiving humidity/temp stats from my one sensor module running on a nano with DHT22 connected. I need to go through and do some major cleanup now, and also figure out how to convert to from F to C for the temp. It seems like the stock code has provisions for that, however I haven't quite figured out how to enable the change yet.

      Thanks for the help - I look forward to implementing more of these sensors.

    • RE: [Tutorial] openHAB with serial gateway

      Not having much linux experience, I'm struggling with getting my serial gateway communicating with openHAB. If I install 1.7.0 in the /opt directory (entirely) this works, however I don't know how to get 1.7.0 installed after having installed 1.6.2 via apt-get - I tried replacing the files in each directory with the updated 1.7.0 files but 1.6.2 runtime is still starting automatically on boot in the openhab.log file.

      I'm also reading that 1.7.0 may not be necessary for this to work, however with 1.6.2 running my USB port is not recognized in openhab - is that possibly due to the port speed being set at 115200 like @Jan-Gatzke mentioned above?

      @Jan-Gatzke

      I am using openHAB 1.6.1 with this rule. Works without problems. You need to compile the gateway with 9600 baud in config.h because openHAB 1.6 has a fixed baud value for the serial communication.

      @Tango2 Here is a tutorial for that. Hope that helps 🙂

      I'm getting closer....

      I have my r-pi2 now, and I'm building openhab on there. I also got my dupont cables I ordered to connect my nRF24L01's up. I now have the r-pi and arduino uno (gateway) connected and wired up.

      Part of the problem I was having before must have been with VMWare ESXI, because now openhab sees my Arduino, however it only sees it on ttyACM0, not ttyUSB99 like it should based on the tutorial above. Should I change the syslink to ttyACM99? The tutorial doesn't specify, and my linux skills are far from good enough to know this off hand.

      I appreciate the help and look forward to setting some of these sensors up!

      EDIT: I did change the demo.items from the link that kunall posted above to reflect ttyACM0, and received the "0;0;3;0;14;Gateway startup complete." message, so I'm making progress, however I'd like to get the static assignment working for stability down the road.

    • RE: openHAB serial communication to Arduino

      Thanks kunall. That's exactly what I was looking for.

      Being new at just about all of this, I'm still having problems. Things seem to be a little different on Ubuntu, so I'm having to adapt on the fly. Currently, dmesg shows my usb devices as "/dev/ttyACM0". I adjusted the rules file to match the corresponding values in dmesg on my machine. I believe the rules file is not working correctly, as I don't have a ttyUSB99 listed. I tried changing the symlink in the rule to ttyACM99 to see if that would make a difference, but it didn't seem to.

      I also tried updating my demo.items file to point to the ttyACM0 that is being detected, however that doesn't seem to work either. I get the following error in my openhab.log file:

      Could not open serial port /dev/ttyACM0@115200: Serial port '/dev/ttyACM0@115200" could not be found.   Available ports are:
      
       at
      

      I'm also seeing this error just before the above error, but can't figure out why the syntax is showing as it is below:

      2015-04-28 13:14:54.004 [ERROR] [i.internal.GenericItemProvider] - Binding configuration of type 'serial' of item ‘Arduino‘ could not be parsed correctly.
      

      This is also after updating to 1.7.0-SNAPSHOT from 1.6.2. Am I missing something simple?

    • openHAB serial communication to Arduino

      I'm just getting into home automation with arduinos, and am planning an openHAB controller with a couple arduino sensor nodes. I currently have openHAB running on ubuntu on a VM, and only have one arduino UNO at the moment (nano on the way).

      I've loaded the gateway sketch onto the UNO and am getting serial output (0;0;3;0;9;check wires) on the serial monitor of the IDE, which I assume is normal since there is no RF board installed on the UNO yet.

      Where I'm having trouble is figuring out how to pass this data over to openHAB. If I understand correctly, the serial connection would work, but I'm having trouble configuring the openHAB side of things if that is the case. I've uploaded the serial binding to the addons folder. What am I missing?
