Hi Everyone,

Has anyone noticed that they no longer receive sensor readings into the Vera Plus? Not sure why and maybe looking to move controllers. Any suggestions on what controller works best without the monthly cost?

@Yveaux

Should have dove deeper when you fist said radio, looks like everything was taken care off except the radio power. Jumped a wire over there and bang worked.

Thanks again for the help.

HI All.

Still having problems and this is my first purchase from PCBway not sure if the code need to be changed for this board but I am using PCB MySensors Gateway Ethernet 3.0 developed by fifisoft57. The radios work on other projects and it is almost like the pins are not correct I traced them and they appear right but......... Has anyone used this board if so did you have any issues? I would say it is my solder job but I did 3 boards one should work.

ANy help would be great.

@Yveaux thanks

Hi Everyone,

I am trying to add a gateway to anther project and this time I am using the W5100 mini and the PCBWAY board designed by FIFIsoft57 (hopefully you see this). The code for the gateway I beleive had to be changed. PLease see my modes below any guidance would be greatly appreciated. This is the PCB MySensors Gateway Ethernet 3.0.

 *
 *
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or receive crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

Hi

Thank you for your reply and I understand that, if you look at the code you will see that pin 3 isn't named/defined in the coed. Unless I am missing something

Thanks

Hi,

I see in the pictures of the connection that the soil sensor is attached to 3.3V, GND and D3 but I can't see where D3 is named. How do you obtain a read from D3 if it isn't named in the code?

Hi All,

I am using the Pete B. Push button concept to turn my kettle on and start boiling and need a little help. When I press the button it will not send the code to turn the kettle on. I used the same wire diagram as Petes ground sample. It is a ground and a simple touch button as I can touch the wires tomorrow to simulate a button and confirmed it’s ground. Has anyone complete code for this and if so can I use it?
Thanks
Tim

Hit post to quick sorry, my plan is to have 4 probes each on a timer. Press the button and put on the steak have Alexa tell you to flip after 2 minutes for rare and the another 2 minutes and she will tell you done with a temp of 125f.....

@alowhum all help greatly appreciated

Hi All,

I am developing a BBQ Sensor that will set a timer for each probe and tell me when to turn it over depending on what I am cooking (i.e 135F = rare, 2 minutes side one and 2 minutes side 2). Any idea if anyone has developed something like this already? I found the smoker files but I am BBQ fellow not a smoker.....

Thanks

Any ideas on how to start? Maybe we can all help.

I figured why wait, this has the temp, hum and 2 relays working not problem. One relay controls my fan for my AV and the other controls my doorbell for my HTD Lync system.

HI

I did get it to work and will post the sketch later today after work. I have it working on the ESP8266 and Arduino.

HI Everyone,

I noticed that I couldn't find a relay working with ESP8266MOD, I was messing with it over the last few days and figured out that the following sketch works. The big fix was in the sketch you use pin 0 for the relay and actually attach it to pin 3. This works great with WEMOS ESP8266.

HI Everyone,

I have my temp/hum sensor in my AV cab and what two computer fans to cool it down. I have tried this and it originally worked with one relay and I got creative and screwed it up. When i tried to get it back to the original version i couldn't as I yes saved over it. I have checked on the forum and see projects like this but they don't appear to work. Can should one give a few pointers?

No matter what i do I still get node 254,. Still most be something I am missing, any ideas?

HI Everyone,

This is the fridge sensor that Bulldog and Pete B put together, I had it working but since the vera update any new mysensors loading always load with the same node id even when i try to change it manually as in the sketch below, any idea what I am doing wrong? The node loads only as 254 node......

Please help.
