Diagrams for Newbie

[Jon]

I managed to get here from the original Uber Sensor Indestructable.  I read through and thought that would be really good as the original author noted, it would be better if the two gateways were made into one.  I'm a complete starter in Arduino but have a good background in computing.  So I've gone out and bought all the bits and then found this site with a better design.  Now the ask, does anyone have more simple diagrams similar to those in the original article as the ones on github.com/computourist/RFM69-MQTT- client are quite hard to follow for a newbie.

Thanks in advance.

Ok, so no takers. Could anyone post photos of their gateways or end nodes?

Ok, here is a picture of my general node setup with Dht22 and photoresistor.

And here are some pics of my gateway setup.
It uses an Arduino Uno, Ethernet shield and the RFM69HW shield I built.
You will see two level shifting modules used to shift between the 3.3V of the RFM69hw and the 5V of the Arduino Uno.

Hmmm, as a former newbie & now maybe as a sophomore (Greek for wise fool), I sympathize. The Uber Home Automation was inspiring & detailed about the possibilities, but the implementation had author admitted limitations, some of which were addressed in comments which were sometimes, but hard to follow what was latest, best practice. The Uber author created this home automation proboard where more reliable builds have been offered, esp. as you mentioned, CompuTourist's (CT). I believe his descriptions are reasonably clear, but maybe do not have all the details a newbie needs. That takes a lot more time, thought & effort. I think CT's schematics are about as simple a picture of circuits as can be, but again it took me awhile to be able to translate schematics into building a circuit. Maybe it'd help to have a pic of a bread boarded circuit where pieces & connections are spread out & easier to see. Bread board circuits don't necessarily translate into more compact builds but still can help. I'll consider this future posts.

At homeautomation.proboards.com/thread/62/success-home-automation-arduinos-rfm69s ("Success Posts"), in a progressing way & especially responding to requests, I'm trying to provide a more detailed narrative of setting up a Home Automation wireless network. You might take a look at that.

You need to get OpenHAB needed components running on some computer device (Raspberry Pi or PC with Linux or a Windows PC). Some of the Uber Home Automation stuff might help with a Linux install. I use Windows 7 instead. I have detailed notes on a Windows install, hope to refine & post them at homeautomation.proboards.com/thread/62/success-home-automation-arduinos-rfm69s

Assembly-wise you might start buying parts for two initial nodes: CompuTourist's Gateway node & DHT End Node. See my "Success Posts" about a minimal soldering build of the Gateway node. My adapted schematic there shows the parts I used. I also gave a picture of my assembled Gateway. If you successfully do this: OpenHAB components installed on computer, Gateway assembled & powered, personalize & install the Gateway arduino sketch, & have the Gateway & OpenHAB computer connected to your home network ... then the Gateway's MQTT connection LED should light, indicating the Gateway is connected to the Computer's OpenHAB components and you've made a good start.

Then maybe (with more at my "Success Posts" or other posts) you'll be more ready to build your first DHT End Node. You might start on that as I did: Experiment with building CompuTourist's DHT End Node schematic as a solderless bread board circuit that makes connections to a (switched to 3.3 volts) Buono Uno's sockets. If you are real careful with power connections (3.3 volts & 5 volts & grounds), you shouldn't hurt much with mistakes. Otherwise keep trying to match what the schematic shows you.  One of the DHT End Node settings is a debug mode which shows some results on the Arduino serial monitor.

Hope this helps some.
