Thanks for the suggestions! I think I will first try the LED stripe way, it's probably the easiest for now.

RE: Receiving but !TSM:UPL:FAIL and no communication? 2.1.1 issue?
@Fabien said in Receiving but !TSM:UPL:FAIL and no communication? 2.1.1 issue?:
In your gateway your don't
#define MY_RFM69_FREQUENCY RF69_433MHZ
. By default it sets to RF69_868MHZOh my god! What an incredible stupid mistake!
I wasted all this time trying to get the NodeMCU to work only because I forgot that setting in my initial Wemos Sketch...
It's finally working now.. haha. Let me know when you're in Austria @Fabien you deserve a beer@Johannes-Hodne thanks for the suggestion but it's finally working now

Thanks a lot for the clarification @mfalkvidd that helps!

RE: why mysensors is based on nrf24?
Why based on nrf24? I came to the party late, but started with RFM69/433 - you are not bound to 2.4ghz in any way, it's just what people used to start with.

RE: why mysensors is based on nrf24?
I'm using RFM69 yes, and it has no problems.
I don't need repeaters at the moment, as far as I know it's software based? -
RE: why mysensors is based on nrf24?
@Reza it depends on the use case I think, peope are using both, both are working. NRF24 is easier to set up and seems to have more support. Just try it

RE: How to use sendBatteryLevel on the controller?
@mfalkvidd Thanks a lot for trying this out! I wondered if it is interpreted or used in a special way by the gateway already.
But in this case I can do that myself.Thanks again!

RE: Security: 433 RFX vs Mysensors security
Thanks for the explanation! I will now rather invest into more Mysensor nodes + RFM69 as it's simply more flexible.
@Nca78 the reason I'm also using mysensors on the temp nodes is that it allows me to use custom sensors (for these types mostly BME280/680).

@nca78 I'm still deciding what to use. Pro Mini if I don't find anything better.
I'm interested in where you buy your BME680 breakout boards, there are not so many around
I think I bought them here: http://www.watterott.com/de/BME680-Breakout
I'm located in Austria

RE: Security: 433 RFX vs Mysensors security
@nca78, unfortunately, I can't make my own boards so I have to use breakout boards.
However, it's not really a problem as I want to stay flexible anyway. -

@mfalkvidd said in Security: 433 RFX vs Mysensors security:
@chbla when combined with encryption, the MySensors signing does a pretty good job of obfuscating what is going on. But since the mere existance of a radio message leaks information, encryption does not solve the problem. Sending fake radio messages at random intervals might be a good way to further obfuscate what is going on, but if an attacker sets up a camera or tracks your phone there will be information leakage again.
Do you have any links to what people use already in terms of encryption?
In any way it's a valid point to say that the likelihood of someone actually monitoring this is quite low.
However, since those chinese 433mhz devices are used so often, it's a bad feeling.
If only they weren't that cheapI wonder how others are doing it, or if most people just ignore that problem?

RE: Security: 433 RFX vs Mysensors security
Yes I have read it, however, it does not address the problem of actually hiding what's going on.

Security: 433 RFX vs Mysensors security
Hi there,
I want to equip parts of house with door/window and PIR sensors.
I initially tought that I will use cheap 433mhz sensors that are integrated with RFXCOM into openhab (which is also the sink for my mysensors network).
They are around 3-4$ per sensor. I would then only use mysensors for things like temperature monitoring, some actors, etc.However, the obvious problem is security. With those cheap 433mhz sensors it is pretty easy to just listen and tell when my basement door or a certain
window is open or not, if someone really wants to (ignoring the chances right now).Mysensors seems to be more secure here, but I assume that there are limitations regarding encryptions.
How do you see this and how do you do it? Any suggestions appreciated..

RE: Low power Distance Sensor - Hardware issues
I need help - I have soldered the whole thing to a prototyping board, and now the Pro Mini keeps resetting.
Does anyone see a problem in the following schematic? (sorry for the drawing, I'm a bit limited here).
As mentioned I'm using a MOSFET, switched on/off via Pin 7.
Mosfet: https://de.aliexpress.com/item/10PCS-IRLB8721-TO220-IRLB8721PBF-TO-220-free-shipping/32714364118.html?spm=a2g0s.9042311.0.0.FjZdIJ
Vreg: https://de.aliexpress.com/item/2pcs-DC-DC-Power-Supply-Converter-Step-Up-Boost-Module-1A-3V-to-5V/32598574742.html?spm=a2g0s.9042311.0.0.IFPbYZ
Lvl Converter: https://de.aliexpress.com/item/Free-shipping-1pcs-4-channel-IIC-I2C-Logic-Level-Converter-Bi-Directional-Module-5V-to-3/32670479389.html?spm=a2g0s.9042311.0.0.OAwsE9It was working fine on the breadboard, but I have verified all the connections.
Right now it seems to reset all the time (2nd LED blinking on the arduino).
The regulator switches on and off with 1hz, the voltage between I+ and I- changes between 1.0V and 2.4V
If I connect GND to the regulator directly, bridging the Mosfet, it works.Any idea?

@qqlapraline good to hear! Thanks for the confirmation

RE: Low power Distance Sensor - Hardware issues
What I mean is, those should be connected to GNDT not GND as in your diagram - right?
GND is permanent ground.I noticed I'm losing current through the trigger pin, the cause is apparently that if disconnected, the system is only on VCC.
Since the trigger bin is set to LOW in my previous sketch, it loses current there.But I found out that if I set the trigger pin to HIGH before sleeping, it's fine. My sketch uses 78ua while sleeping. Using a MOSFET at the moment
to switch.
