My Project

Hello, Here's a simple schematic of the project [image: 1504521460916-captura-de-pantalla-2017-09-04-a-las-12.34.32-resized.png]

@mfalkvidd Haven't tried that. I'll give it a chance just in case.

@gryzli133 Sorry but i dont know how to debug Domoticz

Nice solution. Also that is a very compact (tested and safe) 220V ac -> 19V DC converter inside... hm...

I would use the pin change interrupts. If you search you can find a neat hack for making PCINT work to wake up the micro from MySensors sleep loop. That gives you many interrupts to use.

Great news! I am on the same path, using MySensors and OpenHAB 1.8. But I am using a commercial MQTT broker - CloudMQTT in order to collect data from two physical sites. I am looking forward to reading more about your progress. Keep up the good work! As we move into autumn and I play less golf, I might enter my own story on this forum.

Would be great to see some photo of hardware you have to get this working?

@gohan said in MyWindSensor: since it isn't a pulse counter sensor but it gives a voltage to read it is probably why it isn't cheap A simple pro-mini can do the same; only costs a few €... Looks like it's full metal, so probably a lot more durable than the plastic ones that tend to agree rapidly in the sun...

I try to change the pin 2 by another but my lcd doesn't works. I don't know if it's possible to change the assignment for the pin lcd. To put in place the lcd I have used a tutorial. I have a look on google but a lot of tutorials have the same pin assignment.

@OliverDog when sending to gateway you cannot trust your multimeter. It's probably around 15mA but only during a fraction of a second, and what you read is some kind of average between that and the very low power consumption in sleep mode.

Hi Thank you for the prompt reply, I will have a look. Thanks T

Have been using this for more than a year, without problems http://s.aliexpress.com/iAJRFfY3 I was using a plain 5V solar cell at first, but later I used a rainproof solar LED light as a housing, after removing everything except the solar cell. http://s.aliexpress.com/MR7RjYb2 The node has an NRF24L01 PA version (with the antenna), and communicates with the GW 6 stories below, sending the solar water heater temperature every minute.

@Newzwaver the wiring is pretty straight forward following the above links for the transistors and display. I will try to post a wiring scheme, but that like can't happen within the next two weeks for time constrains. As for the parts list: Arduino nano I2C display, such as the 20x4 character display described here: https://www.mysensors.org/build/display 1 or 2 transistors, I have used the Maverick PR-022 which meanwhile I learned are made of Semiech's 105GT-2 (datasheet: https://www.rapidonline.com/pdf/61-0442.pdf) 1 or 2 resistors matching your thermistor's nominal resistance (for the above: 1 MOhm) The wiring for each of the thermistors and the display is independent of each other following the above guidelines and you can use either one or two thermistors. The display is optional, too. Hope this helps for now. I will post diagrams when I have a chance...

another nice video :+1:
