General Discussion

@tomkxy @Dwalt thank you for your answers! I read that it's better to use the MQTT than the serial gateway - is that the case? and when yes, why? thanks!

@AWI This code runs continuously for 5 seconds in order to get a stable reading of light using LDR, which is used to set night mode on and off.

I use an ftdi cable https://www.sparkfun.com/products/9873 Be sure to use one that can be switched to 5v. I have one that supports both 3.3V an 5.5V. Once you've hooked up the ftdi to the arduino and your make book, you're good to go

@hek said: @joshmosh said: Would gw.begin(incomingMsg, MY_NODEID, true) turn this node into a working repeater ? Yes, this enables the repeater feature. OK,thank you. This will save me an additional node.. Cheers Josh

Hi, why dont you design your own pcbs? Its quite easy... Greetings Andreas

What does you sketch look like? Do you listen for incoming messages and answer the request when it arrives? The node does not keep any state by itself of the last sent message etc. So you have to save these values yourself and send them upon request.

@raulandresmoch Intresting reading on accuracy & lifetime! of temp sensors. Conclusion: The SHT71 does seem to be generally superior to the DHT22. It is better made, at least as accurate, more precise and responds more quickly to change. It does of course also cost ten times as much. Reliability may justify the higher cost, but I have to be cautious because I have not had the Sensirion device as long as the others. Two of my six DH22 / AM2303 devices have failed. Life expectancy is around one to two years. After 18 months of continuous operation only one of my six DH22 / AM2303 devices (device E) is able to match the performance of my one SHT71. Of course it is possible that I got the one good SHT71, but I do not consider that likely. The DHT22 cer list itemtainly is better than DHT11 and easily justifies its``` extra cost. list item

You cannot leave out any parameters in the middle.

@LastSamurai good idea! Will give it a go!

yeah i'm running a bunch. connect to the bottom pin on the top left side (basically not the vcc pin on the bottom) it take 3v and works great.

Did you ever get this going if so can you share the code? My project is similar have a few temp sensors around and send them to an lcd screen node. Lcd can be a repeater to the gateway for logging on domoticz, also if so what extra code did you add on the temp sensor side?

I update my arduino IDE and the version of MySensors and works fine!, thanks anyway!

@hek Thank for the update, it looks very interesting. I have been working on a ESP/MQTT sketch using the ESPWIFI Gateway and the subpub library. I will try the sketch in the development branch. I'm sure you have workout everything I am having problems with :) Regards, Mike

@sundberg84 Thanks for your answer! Now makes a lot of sense and it works I am able to assign ids :)

@tomm277 Here is an example project along those lines.

@Yveaux For your influx flow you can try this : [{"id":"8347dab9.7cb828","type":"mqtt-broker","broker":"localhost","port":"1883","clientid":""},{"id":"d92d398d.26d2c8","type":"mqtt in","name":"Temperature Bureau","topic":"MySensors/4/1","broker":"8347dab9.7cb828","x":159,"y":103,"z":"183ecd0f.e7c133","wires":[["a929fd06.56d6"]]},{"id":"a929fd06.56d6","type":"function","name":"","func":"var newMsg={};\nnewMsg.payload = new Buffer(\"temp,location=Bureau value=\"+msg.payload,\"binary\");\nreturn newMsg;","outputs":1,"noerr":0,"x":354,"y":103,"z":"183ecd0f.e7c133","wires":[["4b2e850f.b4d17c"]]},{"id":"4b2e850f.b4d17c","type":"http request","name":"","method":"POST","ret":"bin","url":"http://localhost:8086/write?db=test","x":505,"y":103,"z":"183ecd0f.e7c133","wires":[object Object]}]

"Is this the same component? and could I use those in the same way as the regular mosfets?" If you are use a 5 meter strip (300 LED and each LED can consume 60mA in "bright white"), you need a MOSFET with ~18A in theory. The IRLL014 has 2.7A which looks like it is not enough. SOT223 is a small size and if you are a beginner it is hard to solder it on a PCB :wink:
