IoT Farm: Blog 13 - Bitter Sweet EnOcean Fruit

jkutzsch

There seems to be Irony that my blog #13 comes with bad news.  I was unable to get my Enocean Pi to work with 3 different Raspberry Pis.  Leading me to wonder if I have a bad Hat.  :-(

 

I worked for days on getting it to link with my Raspberry Pi3 that is running my Farm Operations Center but it would never show as recognized.  Looking at other comments there seems to be a problem with Raspberry Pi 3 and this currently so I pulled out 2 different Raspberry Pi 2s to see if that would help.

 

Regardless of the Pi platform the Enocean Pi could not be seen.  There are some very interesting writeups on installing Enocean Pi and they were quite helpful in trying to troubleshoot what was happening but no success.

 

My desire to use the Sensors are still very high and I am considering ordering another Enocean Pi and another set of sensors since once it works I can see adding more inputs easily.

The Reed sensor is what I want to tie into my sliding Fowl doors and allow for me to trigger when it is open.  Energy harvesting and radio communications, a huge plus!

 

I had ordered a float sensor and was looking forward to seeing if I could tie into the Temperature card since data on it showed inputs that might be of use.  Of course having current Temperature around animals is always a plus.

The Float sensor is to be installed into this Watering system.  The bottom bowl has a float controlled water input.  The 5 gallon bucket would be where the float sensor would reside to alert when the water was low.  As you can see below the bucket, I have planned ahead by putting a T.  The capped part of the T will be routed over to my Rabbit Cages to allow each rabbit to have it's own individual water source via the Chicken Nipples I have previously shown.  The blue bowl will be for my G.O.A.Ts.  Depending on how quickly the water is went through I may tie in another 5 gallon bucket as well.  But that requires future monitoring.

Here is the one complete Rabbit cage.  You can see the individual pvc feeder tubes I have in place.  I want to do similar for the water but have them all tied into the bucket system shown above.  On the left hand side you can see the Baby Box with Momma Rabbit perched on top of the box.

 

I am sad that this part of my plans did not work through and look forward to seeing if I can get another Enocean Pi to fully implement the whole plan of the IoT Farm!

    I'm sure you tested quite a lot of combinations, here are some checks I can think of:

     

    * is there a green LED lighting up on the EnOceanPi ?

    * is there no other program hijacking the serial port?

    * serial interface on Pi 2 and earlier is "ttyAMA0"

    * serial interface in Pi 3 could be either "ttyS0" or "ttyAMA0" depending on how you configured the Pi

    * try following commands to sniff EnOcean traffic (replace serial port to your setup). Clicking the PTM210 (big square) button should generate data.

    • sudo stty -F /dev/ttyS0 57600 
    • sudo hexdump -C < /dev/ttyAMA0

     

    So I'd recommend testing with a B+/2 first, as the serial configuration is easier there (no BT interfering and requiring additional config as on Pi 3).

    The Enocean Pi and the switch design kit both had 902 markings, the sensor kit though I didn't see any specifications. 

     

    My problem has been getting the Enocean Pi recognized in any shape or form.  I went through a variety of instructions that showed how to get the Enocean Pi registered with FHEM, even that video walkthrough, and they all emphasized that it would be recognized automatically and add itself in to the config file and you would see it listed on the left hand side.

     

    I found one instruction set though that said he had problems getting auto registered and he explained how to manually place the Enocean Pi into the config file then to click on the various switches and it would start seeing it.  No luck.  I even went through it all with the Enoceam Pi not installed just to see if it showed something different and my results were the same as it was when installed.  It was like it never saw the Hat.

     

    Not sure if there is a way to return this one, or just order a new one, or what the proper path is.  Next time I will be sure to test all of the stuff ahead of time! 

  • My kit had incompatible frequencies as well.

     

    Do you still have the boxes? What frequency or numbers are mentioned there?
