@TheoL Absolutely you can use it in a presentation. It might be useful (or not) to know that node 105 is a refrigerator/freezer combo, node 102 and 103 are in the same refrigerator/freezer, and node 100 is a chest freezer I have an external thermostat on and I use it as a refrigerator.
I have a refrigerator that has been acting funny lately. I have been watching it display non-normal temperatures for the last couple of weeks. I suspected that the thermostat in the refrigerator is going out. Thanks to mysensors, I am able to monitor the performance of several refrigerators and saw the problem early. I ordered the part I thought was at fault, moved all the vital items out of the refer, and waited (just for fun) for it to fail.
It went out Friday night. I replaced the thermostat tonight. Thanks again to Mysensors for saving 400+ dollars in meat I had in there.

NRF24L01+PA+LNA
Boots33, I completely agree. I have recently decided to rebuild my gateway and I am very pleased this thread came up so I can use the AMS1117. Any idea what the NRF24L01+PA+LNA has the potential to draw? I have looked through the data sheets but I have not came up with a definitive answer.
Although my mysensors network works very well, I am always looking for a way to improve it. I learn something new almost every day from this forum so thanks for your input.
Thank you. I'm not sure how I missed that.

AMS1117
I have nodes running off the LE33 and NRF24L01+PA+LNA shielded that are running on "HIGH" power. I have not had any problems with them although in theory they should not work.
I'm glad you cited the AMS1117. I will give them a try. It looks like they have a max output of 800mA. Is that correct?
I'm not sure the difference in those two but check out the store page:
https://www.mysensors.org/store/#regulators
The LE33 does work with the NRF24L01+PA+LNA but I think the XC6206P332MR would be even better. The LE33 has a maximum output of 100 mA and the XC6206P332MR has a maximum output of 250mA.
My experience is that it will work if you change myconfig.h to low power setting for the radio.
However, for best results I would suggest using a different power source and a LE33 or other regulator to provide significant power for the antenna. The nano only outputs 40mA.
There are a lot of threads that address this question if you dig. I am fairly new here but I use a 5 volt 2 amp power supply when I use the nano with the NRF24L01+PA+LNA. I wire the nano directly off the power supply and use a regular between the power supply and the radio.
Has anyone already done a gateway sketch for the ENC28J60 for Mysensors 2.0? I did not see one in the github.
I am just trying to save a little time.
Thanks.
First off, excellent design. Great job!
I have had one of these running for a while. I did not want mine to react to light levels because I did not want it to close during a thunderstorm, etc. and lock the chickens out. That being said, I have mine close 20 minutes after sunset and open 20 minutes after sunrise. The first couple of nights some of the chickens were locked out because they came home to late. I had to manually let them in. After a couple of days they learned quickly (despite not being very smart creatures) and they head to the house early before the door closes. After that, my camera alerts me to any movement in the house. I have only had one false alarm in a couple of months.
I have a pretty strong outdoor pen and I have still had multiple black snakes, one raccoon, and one possum get in. The raccoon ate a chicken and one snake bit one. After installing the door I have not had one injured chicken.
Mine is pretty low tech. I used a single push button and mysensored a relay board that turns a dc motor with a 3d printed gear that raises/lowers the door. I have had zero problems with it since installed. Thanks Hek!
The one big thing I learned, Transient Voltage Suppressor. I used a larger dc motor due to the weight of my door and every time the door opened it scrambled the Arduino with electric interference. Took me forever to figure out what the problem was and how to fix it.
Now if I can just figure out how to mysensor it to let me know when a chicken lays an egg.....
Yes, it runs fine on the newest Vera versions. I run it on a Lite and an Edge.
