General Discussion

@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":[[]]}]

"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:

@Newzwaver Start here for methods on sniffing the code.

Thanks Sparkman. I searched the forum for the banner message, didn't realize that it had been discussed before without mentioning the contents of the message. Sorry about that.

The nice thing about the MQTT Client Gateway form 1.4 was, that it was the controller too. :) If I need a controller, I will use node-red with the serial gateway. MQTT is then handled by node-red. :)

Use a LoRa transceiver if you want really long range on an ISM band. You can't legally use an FRS/GMRS for sensor data. It's reserved for voice communication.

Magnetic switch or tilt switch (ball or mercury) would be a safe bet. Other possibilities would be a mechanical switch either at the top or bottom (that reacts to the weight of the mail). A light sensor / resistor (which obviously wouldn't work at night) or perhaps some sort of IR beam (not very battery friendly I imagine). Personally I have been using tilt switches for a couple of years. Very jumpy though when it comes to debouncing. Never tried with a capacitor as a simple hardware debouncer but rather just run the tripped message every loop and then sleep at the end of the loop, first for 10min and then until the next interrupt. Domoticz sets the sensor as "off" automatically after a time. A bit hacky but it works it seems. Reading the tilt switch state and getting it right every time became too frustrating. Speaking of debouncers, I was almost desperate enough to look into debouncer ICs like the Maxim MAX6816/MAX6817. Almost. A bigger concern is perhaps radio range. Despite earlier trials that seemed to indicate that the range was ok (and activating ACK), I had to set up a repeater node (with a pa+lna no less, the normal module wouldn't work!) and manually make sure the mailbox node always sends through the repeater. I was planning to set the repeater up eventually anyway, this just forced my hand.

I looked through the areas you suggested but I didn't see any reference to the letters used in the following line of data or how the data is laid out. 0;0;3;0;9;read: 0-0-0 s=0,c=1,t=23,pt=2,l=2,sg=0:455 0;0;1;0;23;455 I did figure out that the last number at the end of the line was the data being sent. Can I assume that you can't use the data directly from the gateway, It has to be connected into a VERA box?

@Cliff-Karlsson said: mys.sleep(BUTTON_PIN-2, CHANGE, 0); Change to wakeUpReason = mys.sleep(BUTTON_PIN-2, CHANGE, SLEEP_TIME); See documentation on wakeUpReason if you only want to send battery value at wakeup.

@Tommy-Sharp the gateway is like the RFXTRX, it has no memory by design.
