Alright, so in 2016 (the 14th of November 2016 started recording into SQL) I created a soil sensor.
I used 3.3V pro mini with regulator removed and powered by Vin pin. Also removed leds from the pro mini.
Connected to a prong inserted into the soil.
Every hour it woke up, measured and sent info to the gateway.
Driven by two AA batteries it showed battery voltage at 3.074V at the start.
In the end of 2024 it showed 2.399 which should be sufficient to get several years more or measurements.
However, one of the batteries had started to leak (cheap battery!).
But it's safe to say this sensor did its job very well with recorded measurements of over 57000 data points!
And to top this I had not the gateway set up some time, but the soil sensor still was on.
So those records are obviously not recorded.

So this little bad boy continued for 8 years with measurements for 6.5 years recorded.
The prong looks like new.

Just thought I'd let you all know this sunshine story

@TimO, cool that you are stil on it, even if it's on the "todo-list".
Kudos and keep up the great work

@TimO , is this binding supported via mysensors MQTT gateway?
In previous bending inormation you had some text indicating that you would implement it. But all that is gone.
So I'm thinking you either implemented it, or aborted that feature

@TimO , did you ever get MQTT to work or do you need someone to test?

I recently managed to build a small irrigation system for my balcony, using mysensors of course!
It was picked up by Sweden's best "smart home"-shop "m.nu" and I had a chance to blog about it.
@hek , I didn't really clean up the code so you actually got credit for it on their facebook page, lol.
Hope you approve or I will make them change it.
Maybe you can see a trade off with the fame and that I also mentioned mysensors.org

Cheers

I was checking back on this bindning and it really has matured!
On GitHub I see that there are some updates referring to MqTT protocol.
Are they available in the JAR that is posted here?
http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.0.0-SNAPSHOT.jar

Kudos on the great work!

After some hours of sleep and refactoring everything, now I think I've managed to get everything working.
I have some problem wrapping my head around "forceTransmit" command and how it works.
Also, millis() is also something I have to learn

Here is the code if anyone finds it interesting.
What it does is measure soil moisture every hour and sends info (normal forkthingie).
Also reading every 30 seconds for temperature and humidity (si7021)
If humidity changes by 1 or temperature by 0.2 it will send info.
If no info has been sent it will force send info every 20 minutes.

3 Relays are there to power water pumps and a LED strip.

i have now semi-learned the use of functions, which is fun
cheers!

Well, it's been a couple of hours now I've been trying to get things to work but now I have to ask for help.
I understand that you can call a function from the loop.
I have combined the sketches: RELAY, SOIL MOISTURE and SI7021 (which is a temperature/humidity sensor).

all parts are working as expected but I want for instance the soil moisture to only be activated and do it's stuff every hour or so.
While the temperature/humidity should be checked every 5 minutes and send info if changed + forced every 30 minutes..
I have gotten it to work, but it's not a nice sketch, and I have problem with the timings.
Because if I call the functions they only work if I add a serial print to see if it's actually counting.
If I comment it out, it will show everything like every 3 seconds..
I understand my sketch is aweful, but it's the best I can do at the moment (still learning).

Someone that could take a look and/or point em in the right direction?
Thanks.

Hey @AWI

I have some trouble using this with MqTT messages.
I can get alarm to go off by sending a payload of '1' to 'InMQTT/62/4/1/0/2' and subsequently turn it off with any other value.

But I can't get the rest of your functions to work!
If I read your code correct, to set a solid color I would have to send several MqTT messages to the children?
Ex, I would have to send 'InMQTT/62/1/1/0/40' and payload ex 'Candle' first.
Then 'InMQTT/62/1/1/0/2' with payload of '1' to turn it on?
I was looking at the serial protocol and do not find what V_Dimmer is for type. (https://www.mysensors.org/download/serial_api_20#variable-types)

Anyways, i cant get it to work properly, maybe you could shed some light (pun not intended ) )?

@Anticimex and @tekka .
I just upgraded my GW (MEGA) and most sensors.
I do not know what you did, but my range is incredible now (and everything works!)
I had good coverage in my apartment before, but if I went outside my front door it started failing (steel security door).
Now, I can not only go outside the door, I can actually go 3 stairs down in my building with AWIs NRF tester.
Same hardware is used and nothing has changed from my part.

Kudos and thank you.

@Anticimex , eh, no apologies needed. I'm thankful mysensors is opensource and actually FREE!
Cool that you found a bug and if I helped, I'm glad

@Anticimex I not sure I follow you and perhaps I am doing it wrong
I power my arduinos via their usb jacket, 5V/2.1A
If I'm using the NRF plate it has its own dedicated regulator hence its getting 3xAAA 4.5V.
Otherwise I am using 2xAA which is around 3.3V connected to VCC/GND of the radio module and GND is also connected to the arduino.

@Anticimex
I power either with 3xAAA (4.5V) if I'm using the plate.
If I'm using only capacitor I power with 2xAA (3.3V).
Tried both versions with same results. Only difference is Arduino/MEGA.
All batteries fresh and also checked with voltmeter

@tekka that was my next goal

I just built an UNO with an ethernet shield and low and behold its working with 47uF capacitor.
Conclusion:
MEGA does not work with NRF plate adapter nor 47uF capacitor.
UNO works with 47uF capacitor only (not with plate).

All nodes are reporting in (mixed 2.0 and 2.1).
I use @AWI quality meter with NRF plate board to test as well and it is OK.

So same NRF hardware yields different results on UNO and MEGA for me.

@Anticimex maybe I was not clear enough or used the wrong words?
I still understand that the problem is not with signing.
I pointed out that using signing provokes the error.
The error is still an underlying issue weather it be my hardware or it be NRF module code in mysensors 2.1.

Well so I deleted whole Arduino to make sure I got everything fresh.
Installed arduino and mysensors 2.0 via library manager and also mysensors HW arduino manager in preferences.

Updated my gateway and all nodes work with signing ON.
The nodes are a mixture now with mysensors 2.0 as well as 2.1.

I updated library to 2.1 in my GW and instantly I have failed messages with Signing ON.

To make sure, I powered the GW from one source and NRF separately from external source (5v computer usb)
No changes. I tried different NRF as well as NRF PA with big antenna.
I even tried different antennas (used to other applications). With mysensors 2.0 they work, with 2.1 fails.

I took a node and powered it similar with external power source (3x1.5v AAA) for the NRF but it would still give me fails.

When I go back to mysensors 2.0 everything works great again.

I guess I'll stick with 2.0 and wait and see if other people upgrade their stuff and use signing might see the same problem with their hardware.

@Anticimex I understand that the problem is not with signing itself.
I also understand that with longer messages with low power things it gets extra difficult.

What I am saying is mysensors 2.1 did something and my hardware can't cope with it.

I have tried socket adapters for NRF modules.
I have tried giving them external power.
I tried without socket adapters.
Giving external power as well.
I have tried 47uF capacitator.

Mind you, I have tried several different hardware pieces as well just to make sure.

I will redo everything above again just to make sure and report back.

@tekka Im not saying it doesn't work, but it doesn't work

I have spent some hours yesterday and today testing different possibilities.
However, as soon as I enable soft signing it just my nodes get no reply or partial reply sometimes.

If I disable softsigning in GW, everything works perfect.

I would guess that the problem could be with my hardware as everything except my ethernetshield is china clones.
But since I had used everything and everything worked without a flaw (with signing) and the only thing I did was update library via arduino, and uploaded the same sketch (without editing it) to the GW.
I would beg to differ that something is not broken with mysensors 2.1. Or atleast maybe compability has been lowered.
Or mysensors 2.1 changed something in the use of the NRF chips (the + as well as PA with big antenna!).

I uninstalled arduino completely, but had some problems installing 2.0 as it complained about some stuff about my arduino mega. But when I installed 2.1 it worked with mega which is also weird.

It is no biggie that signing doesn't work for me, but It bugs me that this should be simple and it isn't.

To sum up:
My NRF works without signing. It even works behind steel heat radiators across my flat (yes, did that for testing purposes!)
Switch on signing and I can barely connect to my GW.

@Anticimex

I had built the NRF tester and had perfect coverage with no drops in my apartment before (with signing!) from any of my NRFs.

To test further I even put one of those plateboards for testing NRF to my gateway. Added external power from another source.
Did the same to my NRF tester but still it fails.
Have put them close and also gone around in my apartment to eliminate distance signal error, still the same.
So only difference is mysensors 2.1.
However, since no one else is complaining then maybe the problem IS with my setup.
Or could also be that no one else has updated

I'm using Arduino 1.6.11, maybe I should install 1.8.1?

So I took the plunge and sent the same sketch as I had when using mysensors 2.0 to my Arduino Mega with w5100 ethernet shield.
It is the MQTT sketch.

After this I could not use any nodes with signing.

LOGS as follow.

Anyone else with the same problem (ping @Anticimex )?
I downgraded my arduino boards to 1.6.11 as per instructions in some other posts.
I also ran the signing sketch again (software backend) on my nodes, but to no avail.

//Nicklas

@mfalkvidd , quite OT, but how do you power these?
I have them as well and when I calculate how much amp they should draw it is quite much!
However, when I check what they actually draw is quite low. Around 3-4A on full bright white.
Do not really know what I should aim for because you can find nice 5A or less quite easily while above this you would have to go with big ugly power supplys.
And it's a shame they work in 5V only as 12V would be much better for me (and get more A out of as well from smaller power supplys)

@joshmosh I use MySensors V2 and took a sample every 30 seconds over a few days simulating almost 28000 transmits.
I've come down to have roughly 0.08V decrease for all these transmits which is very close to what @mfalkvidd has.

@TON-RIJNAARD , here is my sketch! I think I use signing as well, so if you don't use it just remove

Just stumbled across this binding great work!
Until now I have used MQTT binding and MQTT gateway.
Will try this later on.
However, is there a reason why this binding is not part as downloadable from within OH2?
Cheers

@Michael_K ,

If we go from the front to the back this is what is needed:

1 Node: For example a door bell.
This node sends information to a gateway.
2 The gateway takes the message from the node and sends this to a controller. For instance Openhab or Domotics. This can be done in several ways. MqTT being one.
3 Controller: takes the information and displays it to you.

So in my case, I hardcode Node ID and CHILD ID (the complete door bell is a NODE whereas CHILD IDs may be the button pressed and maybe temperature reading at the same time).
This sends to Gate way that takes the information and creates a MqTT message.
What this message is, please read the instructions on this site.

@Michael_K ,

I think you mean you want to use the Gateway WITH MqTT
https://www.mysensors.org/build/mqtt_gateway

This works very well and I'm using it myself.
I have the MqTT broker on a raspberry pi.
And the gateway is an arduino with W5100 ethernet board.

@siod and @LastSamurai
Connect the REED Switch with one leg to GND and the other leg to PIN2.
And then you put a 1MOhm resistor between VCC and PIN2.

@joshmosh , actually there is so many variables that it is impossible to check and the term "milage may vary" is spot on.
All batteries are not the same.
Temperature.
Arduino.
Time between readings (some batteries prefer small current over time and some handle bursts better).
etc

I've set to report moisture every 30 seconds and obviously the voltage report from an arduino is not 100%. And with that said, it is probably not 100% consistent neither as it could differ between readings as well.
The only real way to tell is know starting point via multimeter and then check after a month what has happened.
For me, doing a check, I've come down to 0.08V per 76000 readings.
I did the estimation based on about 8500 readings and extrapolated it to 76000 reports based on @mfalkvidd information.

For me, this is enough and I'm sure my sensor will survive for a long time and can now program it to take more reasonable moisture readings. Example, 1reading/h for the plots that dries the fastest (in direct sunlight) and less when they are in the shade.
In the spring the balcony will have several sensors with automatic watering

@AWI OMG there is so many options when you look at it!
I think it all boils down to design (size) or money.
Normal AA roughly 0.3EUR/pc are quite large but OK power but cheap
CR123 roughly 2.5EUR/pc are quite small and OK power but expensive
Coin cell roughly 1EUR/pc and they are the smallest but not packing a good punch while being semi cheap/expensive.

Obviously I have to build one node with each and put them in flowerpots around the flat to see in in action

And to top it off, I know there is a company in USA that has created a new battery that will double 'Ah' in same size batteries. They should launch this month i think, but think they will go for cellphone makers in the beginning.

@mfalkvidd that is really awesome!

Did you set any Brown Out Fuses?
From what I gather the arduino pro mini will stop working at 2.8V and you have to set other fuses for it to reach the lower voltages.

I did a quick test with one flowerpot and from what I see my power consumption will be around 0.2V per year. It's more than double of what you're getting. But still low enough as changing 2 AA over 1-2 years is OK in my book if I'm not changing the fuses

EDIT: Actually, calculating with your numbers of updates I get around 0.6V consumption per year for my setup and that is far from your low power consumption.
I think I will have to go through this thread once more to try to find why the difference is so big and what you have done. I see 2 potential culprits. One is the arduino mini pro (china clone without power LED and voltage regulator) or maybe it could be my mysensors 2.0 version vs your 1.6.

@AWI in the first part it states:
"Primary cells such as lithium-metal and alkaline retain the stored energy best, and can be kept in storage for several years."
So you are correct and between Alkaline and Lithium-metal maybe the latter would be best.
I have no experience with coin cells and will do some testing with them as soon as I can.
Since this is the battery article, would you please tell me what you use and how you use it. What you expected and if the batteries lived up to your expectations. Would be cool to know as you've had more experience then me (and many like me)!

Good article/site on why Alkaline is the best way to go for Mysensors nodes
http://batteryuniversity.com/learn/article/elevating_self_discharge

@siod , I had the same problem.
I actually ordered a original NRF 24 mini and this seemed to solve some of my problems.
i think another problem I'm having is that my batteries has a huge self discharge (old 3.7v 18650)

On a side note.. I'm with @sling .
Loose the pullups and set them LOW´.
I have a 1MOhm resistor between VCC and PIN 2 and PIN 3 (also 2 switches).
Using the pullup HIGH draws around 130uA versus LOW it draws between 7 to 10uA!

@hek , I've read that post several times
Since it was so outdated (2 years) I naturally assumed the 'battery powering article' was a newer way to do it (especially since mys2.0).
Also, the post you linked to is attributed if you use no voltage regulator.
And in the article this is also one of the things you are recommended to remove, hence making it even more confusing as to why the article describes another way than the post.

@gloob thanks!
One would think running with no resistors and not using a separate PIN would be better.

@hek or @mfalkvidd , any comments as to why the original sketch is preferred over the other 'way' in this article?

Another battery related question that I really do not understand.
Are there different versions on how to read battery consumption?

I see some sketches uses:

long readVcc() {
  long result;
  // Read 1.1V reference against AVcc
  ADMUX = _BV(REFS0) | _BV(MUX3) | _BV(MUX2) | _BV(MUX1);
  delay(2); // Wait for Vref to settle
  noInterrupts ();
  // start the conversion
  ADCSRA |= _BV (ADSC) | _BV (ADIE);
  set_sleep_mode (SLEEP_MODE_ADC);    // sleep during sample
  interrupts ();
  sleep_mode (); 
  // reading should be done, but better make sure
  // maybe the timer interrupt fired 
  while (bit_is_set(ADCSRA,ADSC));
  result = ADCL;
  result |= ADCH<<8;
  result = 1126400L / result; // Back-calculate AVcc in mV```

However some (like the original one in this thread) uses:

 int sensorValue = analogRead(BATTERY_SENSE_PIN);

Is it due to different libraries or maybe it is the same but just programming wise different?

@Yveaux and @mfalkvidd thanks!
It's not important for me, just curious to know why

Hello,

I use Sleep on one of my nodes and then wake up to report to GW.
It is set to sleep 3600000 which should equivalent to 1 hour (10006060).
However, I can see that this is not the case.
My node wakes up, but about every 1hour 9 minutes instead to report.
I'm using a arduino pro mini (chinese) so obviously this could be the culprit.
Just wondering if anyone else has seen this

@parachutesj you have to modify the pro mini. Remove the power led according to instructions!

@Martin-Tellblom , how is your project going!
Did you manage to get longer lasting nodes?

I have one reed magnetic switch. It seems this only draws 7-10ua in sleep mode and upwards 17ma when sending.
However, it still drains my batteries very quick which I find odd.
It wakes up once every hour to send and that should not be much..
Could be that my rechargable battery is bad so I'll try to replace it with 2AA instead of one 3,7v.

@mfalkvidd , it was too late at night for me.
I had it at current but it didn't show anything. So without thinking I put it at voltage.
And the problem with not showing anything when I had it at current was I had blown the internal multimeter fuse some days ago.
Ehrmm.. yes. move along, nothing to see here

@mfalkvidd that's what I thought! I see that I'm getting 3.4V in the multimeter but my pro mini nor nano will start up (I have not removed the LEDs so they should light up).
If I use more V (6.8V) I put in via RAW on the PRO mini, and I can see teh voltage, but the same thing, it's not starting up, hmmm I wonder what rookie mistake I'm doing!

Sorry, where do you measure the power when it is in sleep mode? ie, where do you put your multimeter probes.

@EasyIoT , how are your sensors doing, its been 2 years
And also, @m26872 , the node 105. Is it alive?

Regarding ACK flag in MQTT.
If a sensor sends data to the gateway, and it requests an ACK.
It is the gateway that responds with an ACK, not the controller.

How do one utilize the ACK flag in MQTT?
Or rather, how do one get the ACK to display in a MQTT message?

void receive(const MyMessage &message) {
int value = debouncer.read();
//We only expect one type of message from controller. But we better check anyway.
 if (message.isAck()) {
    Serial.println("This is an ack from gateway");
 }
}

Should I write a codesnippet like the above but one that sends a message back to the gateway, that the ACK was received?
And also, if an ACK was not received that the sensor should try to send the message again.

@Martin-Tellblom , I'm in this mess as well. Just ordered a new Multimeter off aliexpress

@sundberg84 , have you tried other batteries? I bough some ultrafire 3.7V 8800mAh and will try these.
They were cheap so no loss if they do not work out..

@AWI what is the board between the nano and the radio?
Something available via aliexpress?

I really do not need this as I live in a small flat.. but I NEED THIS!

@Anticimex yes. But since his neighbours nodes aren't signed (or with wrong signation), the repeater will not forward them to his gateway.
Or am I totally wrong?

@Reza
From what I understand the GateWay will add all nodes even if you do not want them to. But not to the controller if you have "inclusion option" on the GateWay.
There is a possibility that if you use the "inclusion option" maybe it will pick up all sensors not already added (ie your neighbour) if they are sending while inclusion is looking for new sensors.
If you want to stop this you will have to use whitelisting on MAC adress. But this requires you to reprogram GateWay everytime you want to add new sensor (or maybe it is possibility to have same MAC for all?).
And of course you will have to program a MAC adress for all sensors/per sensor the first time as well.
I thought this problem would be solved with only using Signing, but because of backwards compability the creators did not enable this in the GateWay.
If you only would want signing, you could make all nodes connect via a repeater node.
Because between repeater nodes and regular nodes signing is enabled and no other nodes is accepted which aren't signed with correct signing
And if you use Whitelisting only between GateWay and repeater node, you are set.

Note: I could be wrong

@scalz said:

@Reza
Finally, the inclusion mode. That's mostly the feature you need, because it could help you to block new nodes. I think this is a feature that the controller has to implement. I don't use inclusion mode in mysensors (not tried yet),
but in the controller I'm using (jeedom), it works well. There is one inclusion button (I don't advice you to use jeedom, it's french! and not 2.0 full compliant). As you can see this is possible to have a working inclusion button in controller

You have to use whitelisting to block nodes. 'Signing' in GateWay does not work as it accepts non signed nodes. Signing primarily is used for nodes receiving info.

@mfalkvidd thanks!

I actually found the problem while messing around with different settings.
I changed 'uint16_t' to regular 'int' and it started working!
Now, both should have worked (I guess by doing a quick google on uint16_t).
So as to why how what.. im perplexed.
Thanks for looking at the code

Hello,

The sketch itself is working alright and reads/sends the information.
The humidity/Temp waits until the threshold is reached before sending the message.
But my Lyx sends it really random and not accompanied by the threshold I've set.
Are the tags wrong?

Also, since I am a newb, in the sketch there is this row:
SPIFlash flash(8, 0x1F65);
What does it do?
I figured it sets the I2C adress for the SI7021 chip?
However, since I have not set any I2C adress for the BH1750, is this done within the library "#include <BH1750.h>"?

I just checked my sensors and I'm using 470µF.
Shows to go you really should check what you grab from a bag of capacitors

@Anticimex

ahh, so basically the gateway will always accept everything, but nodes will not if signing is enabled.

Maybe it's a longshot, but I was worried that if someone knows my MQTT pathways they would be able to
1: Use a node and send information (ex MQTT/MyActuator/TurnON)
2: The gateway picks it up and converts to MQTT information and publish to MQTT broker
3: My actuator subscribes to this special channel and gets the "TurnON"
And then for example turns on my lights or whatever.

While I was writing this I realize more and more that the above is pretty far fetched
Also, I have separated MySensors channel from other channels so they should be safe.

But to be on the safe side and there seems not to be any apparent drawbacks, I will use Whitelisting as well.
Thank you for the help @Anticimex !

@Anticimex great!

So flashed my gateway and 1 node.
How do you know it "works"?
In my gateway and node sketch I have included:
#define MY_SIGNING_SOFT
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7
#define MY_SIGNING_REQUEST_SIGNATURES

Reading the document I would expect that all other nodes that isn't "signing" the information would be disregarded by the gateway.
But in my case they can send info to the gateway and it will forward it via MQTT (as I have the ethernet w5100 gateway with MQTTclient).

Using serial monitor on the gateway this is what is seen when a signed node is reporting:
0;255;3;0;9;TSF:MSG:READ,4-4-0,s=0,c=3,t=16,pt=0,l=0,sg=1:
0;255;3;0;9;TSF:MSG:SEND,0-0-4-4,s=255,c=3,t=17,pt=6,l=25,sg=1,ft=0,st=OK:5D7FA0C430E8A0363FEBA8E73BDBBD2755DFC7A53E8D1B394F
0;255;3;0;9;TSF:MSG:READ,4-4-0,s=0,c=1,t=16,pt=2,l=2,sg=1:0
0;255;3;0;9;Sending message on topic: Broker/1/0/1/0/16
0;255;3;0;9;TSF:SANCHK:OK

A node that isn't signed:
0;255;3;0;9;TSF:MSG:READ,2-2-255,s=255,c=3,t=7,pt=0,l=0,sg=0:
0;255;3;0;9;TSF:MSG:BC
0;255;3;0;9;TSF:MSG:FPAR REQ,ID=2
0;255;3;0;9;TSF:CHKUPL:OK
0;255;3;0;9;TSF:MSG:GWL OK
0;255;3;0;9;!TSF:MSG:SEND,0-0-2-2,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0
0;255;3;0;9;TSF:MSG:READ,1-1-255,s=255,c=3,t=7,pt=0,l=0,sg=0:
0;255;3;0;9;TSF:MSG:BC
0;255;3;0;9;TSF:MSG:FPAR REQ,ID=1
0;255;3;0;9;TSF:CHKUPL:OK
0;255;3;0;9;TSF:MSG:GWL OK
0;255;3;0;9;TSF:MSG:SEND,0-0-1-1,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=OK:0
0;255;3;0;9;TSF:SANCHK:OK

To me it looks like it's ignoring the node because no temperature is received and shown in serial monitor.
But it still reports everything via MQTT.

Am I doing something wrong?

Hello,

Before I do anything stupid
I followed the documents but want to clarify so...
I used SecurityPersonalizer.ino and uploaded it to a node.
The results were just a bunch of "FFFFFFFFFFFFFFFFFFFFFFFFF".
I defined my own MY_HMAC_KEY, MY_SOFT_HMAC_KEY, MY_SOFT_SERIAL and MY_AES_KEY with different values.
Uploaded it to a node and it saved it in EEPROM (I ran the original sketch to find out what was saved)

1: Do I use the same SecurityPersonalizer.ino to my gateway and all nodes so they all have same keys?
Or do I have to change any key?

Thanks!

@FotoFieber

How do you mean it is a problem? Everything works, just needed to know what the extra was
I too use NODE RED, but just listening on MQTT and then putting the info into mysql databases.

@hek
Thank you! I have used search, but it is difficult when you do not know what you are searching for And all information about 2.0 is overwhelming at the time being for me.

Quick question.
I have built GatewayW5100MQTTClient according to mysensors.
It works and relays my nodes.
However, my old gateway with MqTT delivered the messages with my selected prefix and then node/child number + variable/sensor.
Ex MyMQTT/1/1/S_TEMP
Now the new gateway with MqTT delivers node and child and more like this:
MyMQTT/1/1/x/x/x where X is some number.
It does not display S_TEMP.
And what are the extra "numbers"?

And it also displays when the node starts up some MqTT messages that are empty ex:
MyMQTT/1/255/3/0/1 with no information.
I do not know what publishes these..

For relevance, the sketches I upload are the ones in the new mysensors library, ex Atmospheric Pressure Sensor.

@mfalkvidd , I think there has been many discussions on how these sensors corrodes over time.
I can see that this node sleeps between the readings and thus reduces corrosion as it only is powered during reading.
However, some threads I've read suggests that you alternate the power, as well, between readings.
Something you might implement in the code?
Also, do you have an estimate on the duration usage on the batteries for one of your plants?
Cheers!
