@jpaulin

Thanks for posting the code!

I had to take a break from the home automation world for a bit. So, it was great timing that you posted. I'm building my MQTT gateway with the w5500. I'm not completely ready to try the rfm69 yet!!!

Thanks again!!!

I am struggling to get the USR-ES1 to work. I am using IDE 1.6.11. (At this point, I am only trying to get the WebServer to work) It looks like all of the libraries are set up correctly, by default, i.e. the #define (#define W5500_ETHERNET_SHIELD) that you mention above is already uncommented. There must be something else that I am missing??? All that I see from the debug window is "server is at 0.0.0.0"

Any chance you would allow me to see your code for your gateway?

Thanks again!

Rob

@jpaulin I see that you are using the W5500 chipset on your Ethernet module... According to the specs of the W5500 chip, it looks like it has a MAC address. Have you tried to get a DHCP address using the native MAC Address of the W5500?

I'm considering going with that USR-ES1 as well. I like the small form factor, but I won't waste my time if it doesn't already have a MAC address. Backup plan is the W550io, which supposedly has MAC address embedded. Same chipset.

Thanks!

@petewill UGH!!!

DOH!!!

I'm a little embarrassed that I did not see all of the previous posts that actually brought up the 9v interconnect voltage, or the actual link to the original site that you mentioned.

I have to say that you have a lot of patience for guys like me that are too impatient to read all of the previous posts and want the answers without working for them. For that, I apologize. Yeah, I was up late... Blah, Blah, Blah! If only I had read from the beginning!

I have learned so much from your content.

Now it's time to study your code and understand how you are able to differentiate the pulses from CO to smoke detection.

BTW... I'm looking to supplement the existing battery powered smoke detectors that are in the halls of my home. I'll be looking closer at the Kiddie brand soon. Any chance you have a model number for your CO, smoke and/or combo detectors?

Again...

Thanks for all that you for the DIY'rs out here!

@petewill Sorry, total newb question... and, it's 4:00 AM here... so, I might be communicating in circles...

I don't understand what the optocoupler is used for in this project, so please help me...

...the interconnect puts out a (12v?) reference signal, and for that signal to be useable by arduino, the voltage needs to be lowered to 3.3 volts? The voltage is lowered by the resistors that are in series? How much voltage is coming out of the resistors? (or what voltage is going into the optocoupler?)

I understand the basic concept of an optocoupler... I guess I'm confused about what kind of signal is coming from the interconnect. (analog or digital?) Is there
actual data coming from the interconnect?

I also understand that an optocoupler is kind of slow? (Based on a quick reference, wiki, of course). I guess I thought that an analog to digital signal convertor would be required to gather the information coming from the interconnect. So, I can't figure out what the optocoupler is doing for this project.

Thanks for putting out great projects and videos! I've learned a ton!

Again, apologies for the stupor of my late night questions, and for me dragging this topic out of the grave.

@cimba007 --- That's great information!

I'll try this out!

Thanks for letting me butt into your topic...

Rob

@cimba007 -- I really didn't know that the Arduino already had a WDT... But, what if it is the Atmega that is locked up? I suspect that my clone Arduinos are susceptible to heat and are unable to reset themselves... (Yeah, a bigger issue that what this topic is about). Thanks for the information!

Rob

Not that I know anything... About anything... Yeah, I'm new here...

What about using a hardware WDT? For instance the freetronics one?

I have sensors up in my attic and have been thinking about using a hardware WDT.

During the summer, it gets really hot up my attic, and I hate going up there.
