@jvdk I agree with the point made by @evb , why would you want to wire connect the ultrasonic node rather than the usual radio connection ? You are adding levels of complexity and power demands for what reason ? My ultrasonic water tank node (pro-mini+rfm69) is now 2 years on the same 2xAA batteries sending in levels every hour (RTC), the only problem encountered - condensation forming a drip on the face of the ultrasonic head during very low temperatures.

This is my temperature-humidity-pressure sensor in a 1151v3wh enclosure. [image: 1614529133148-img_20210228_171133-resized.jpg]

@mfalkvidd Thanks - you are on fire today (that was quick reply)! ;)

Hi, Well progress, and questions ! When I started this with the Teensy3.2, I used a RFM69CW (smaller pcb) device, and ran into the problems as detailed above. As part of the troubleshooting, I part assembled a "EASY PCB" which I have, to enable, hopefully proving a different radio module (RFM69HW) which is my normal radio module, and attempt to "tight fit" a Pro mini to header pins on the board, to "prove" the radio. This was sucessful, as mentioned above. Using this proven radio / assembly, I removed the Pro Mini, and jumpered to the Teensy with dupont cables, which got the radio "working" in the sense that the transport succeeded, it just couldn't find the parent / gateway. I mentioned above the possibility of connecting the reset pin, as I had the origional bare RFM69CW already to go, I soldered another wire to the reset pad, and utilised this at the radio, commenting out the #define MY_IS_RFM69HW . and adding the #define MY_RFM69_RST_PIN 9 . I uploaded this, and it found, and presented to the GW / Controller. BUT subsequent messages were met with "!MCO:SND:NODE NOT REG" as in the log below 300 MCO:BGN:INIT NODE,CP=RRNNT---,VER=2.2.0 300 TSM:INIT 300 TSF:WUR:MS=0 301 TSM:INIT:TSP OK 301 TSM:INIT:STATID=44 301 TSF:SID:OK,ID=44 301 TSM:FPAR 1529 TSF:MSG:SEND,44-44-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK: 1547 TSF:MSG:READ,0-0-44,s=255,c=3,t=8,pt=1,l=1,sg=0:0 1547 TSF:MSG:FPAR OK,ID=0,D=1 3530 TSM:FPAR:OK 3530 TSM:ID 3530 TSM:ID:OK 3530 TSM:UPL 3536 TSF:MSG:SEND,44-44-0-0,s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=OK:1 3747 TSF:MSG:READ,0-0-44,s=255,c=3,t=25,pt=1,l=1,sg=0:1 3747 TSF:MSG:PONG RECV,HP=1 3747 TSM:UPL:OK 3747 TSM:READY:ID=44,PAR=0,DIS=1 4774 TSF:MSG:SEND,44-44-0-0,s=255,c=3,t=15,pt=6,l=2,sg=0,ft=0,st=OK:0100 4985 TSF:MSG:READ,0-0-44,s=255,c=3,t=15,pt=6,l=2,sg=0:0100 6218 !TSF:MSG:SEND,44-44-0-0,s=255,c=0,t=17,pt=0,l=5,sg=0,ft=0,st=NACK:2.2.0 6234 TSF:MSG:SEND,44-44-0-0,s=255,c=3,t=6,pt=1,l=1,sg=0,ft=1,st=OK:0 6459 TSF:MSG:READ,0-0-44,s=255,c=3,t=6,pt=0,l=1,sg=0:M 7492 TSF:MSG:SEND,44-44-0-0,s=255,c=3,t=11,pt=0,l=9,sg=0,ft=0,st=OK:test Node 7502 TSF:MSG:SEND,44-44-0-0,s=255,c=3,t=12,pt=0,l=5,sg=0,ft=0,st=OK:1.0.0 7515 TSF:MSG:SEND,44-44-0-0,s=5,c=0,t=33,pt=0,l=14,sg=0,ft=0,st=OK:Motion RX RSSI 7729 TSF:MSG:READ,0-0-44,s=5,c=0,t=33,pt=0,l=14,sg=0:Motion RX RSS 7729 TSF:MSG:ACK +Ack FMGW *InMsgty :33 MsgComd:0 childID:5 Switch:0.00 7936 TSF:MSG:READ,0-0-44,s=5,c=0,t=33,pt=0,l=14,sg=0:Motion RX RSS 7936 TSF:MSG:ACK +Ack FMGW *InMsgty :33 MsgComd:0 childID:5 Switch:0.00 8141 TSF:MSG:READ,0-0-44,s=5,c=0,t=33,pt=0,l=14,sg=0:Motion RX RSS 8141 TSF:MSG:ACK +Ack FMGW *InMsgty :33 MsgComd:0 childID:5 Switch:0.00 8344 TSF:MSG:READ,0-0-44,s=5,c=0,t=33,pt=0,l=14,sg=0:Motion RX RSS 8345 TSF:MSG:ACK +Ack FMGW *InMsgty :33 MsgComd:0 childID:5 Switch:0.00 8937 TSF:MSG:SEND,44-44-0-0,s=4,c=0,t=1,pt=0,l=9,sg=0,ft=0,st=OK:Prescence 9149 TSF:MSG:READ,0-0-44,s=4,c=0,t=1,pt=0,l=9,sg=0:Prescenc 9149 TSF:MSG:ACK +Ack FMGW *InMsgty :1 MsgComd:0 childID:4 Switch:0.00 10225 TSF:MSG:SEND,44-44-0-0,s=6,c=0,t=30,pt=0,l=16,sg=0,ft=0,st=OK:Motion Battery V 10226 MCO:REG:REQ 10234 TSF:MSG:SEND,44-44-0-0,s=255,c=3,t=26,pt=1,l=1,sg=0,ft=0,st=OK:2 10444 TSF:MSG:READ,0-0-44,s=255,c=3,t=27,pt=1,l=1,sg=0:0 10444 MCO:PIM:NODE REG=0 10445 MCO:BGN:STP 10445 MCO:BGN:INIT OK,TSP=1 Motion 0 10495 !MCO:SND:NODE NOT REG 10647 TSF:MSG:READ,0-0-44,s=255,c=3,t=27,pt=1,l=1,sg=0:0 10647 MCO:PIM:NODE REG=0 RAWbatcount :179 batV :0.74 batP :0 10850 TSF:MSG:READ,0-0-44,s=255,c=3,t=27,pt=1,l=1,sg=0:0 10850 MCO:PIM:NODE REG=0 10857 !MCO:SND:NODE NOT REG 10857 !MCO:SND:NODE NOT REG wait 10000 11258 TSF:MSG:READ,0-0-44,s=255,c=3,t=27,pt=1,l=1,sg=0:0 11258 MCO:PIM:NODE REG=0 Progress of a sort. I noticed however that in the Controller, each child presentation, including the MYSENSORS version was missing the last character. I have seen this sort of thing in entirely different situations with serial coms, baud rates mismatching slightly (due to processor speed dividing ratios), and I knew that out of the box, the teensy runs overclocked at 96Mhz, so I changed the speed of the processor, to 72Mhz, and uploaded, had the same results, Then I selected 48Mhz, and uploaded again, and Eureka, it all works. So in summary, I have wired in the Reset Pad to (in my case) Pin 9, and slowed the Processor to 48Mhz, and all is working.

@Bartosz-Nowak there is a long thread on this forum on the nrf52840. You could have a look there how to get things working

@monte said in Favorite hand solderable radio chip?: @NeverDie so is it directly compatible with nordic's protocol? Can it be used as drop-in replacement for nrf24? From MyConfig.h (obviously the assumed vendor is wrong :) ) There are some settings also to fix the ACK that is reversed compared to NRF24. /** @defgroup RF24SettingGrpPub RF24 @ingroup TransportSettingGrpPub @brief These options are specific to the RF24 family of wireless transport modules.

Thank you all, the last offering is ideal. As it happens, it also covers the device I wish to use, for physical size and program storage capacity. Teensy' 3.2 Many thanks, look as I might I couldn't find it.

Thank you so much. I did not found any schematic for those boards. And the diode and polyfuse are not on the sparkfun design. The diode let me crazy when trying to verify and trace the signal with multimeter. I take a long time before understanding why my multimeter some times say connected, sometime say not connected. And this night, I tell myself : it's a diode :) Thank you again !

@ricvice You have reached the 'interesting' point now. You have the hardware, you sort of know what you want, but need to learn how to do it. We have all been there! So start with a clear idea of the system. Where are the displays going to be etc. Then try to make it work. Start off with simple sketches that do things like measure analog voltage (see battery powered sketch) This will be useful for the wind speed. Then look at the 'build' section at the top of this page for temp sensor. Again, try it and see how it goes. Gradually things will become clearer and you will be able to try and combine sketches into one that does it all for you. Small steps go a long way with this. You will need to make a gateway and choose a controller to use mysensors and display data, but you can easily see graphs etc so it could be worth it for you. A simple raspberry pi 3 and a pro mini would do for controller and gateway. If you get stuck or can't figure something out then post on here with your code and someone will help you. IF you don't want to go the mysensors route then the arduino forum would be a better place to ask as this is really only for mysensors related discussions.

Sorry for not giving news. So I've done lot of tests, triple check everything and still found "nothing" I test with deepSleep sketch from lowpowerlab, and still have high current. I finally receive new rfm69 and change it. And it's ok now !!! I have 25uA when sleeping !!! Don't know why, but with new one, it's ok :) Thank you again for your help and your ideas

Hello, You can use this solution. I use this with attiny84 and attiny84A, for temperature sensor and opening sensor. http://domotique-diy.overblog.com/

Here is my code for doing something equivalent. You seem to have the pinMode line missing in setup() // Initialize motion message MyMessage msg(CHILD_ID, V_TRIPPED); void setup() { pinMode(MOTION_SENSOR_PIN, INPUT_PULLUP); // sets the motion sensor digital pin as input } void presentation() { // Present locally attached sensors here // Send the sketch version information to the gateway and Controller sendSketchInfo("Motion Sensor", "1.1"); // Register all sensors to gw (they will be created as child devices) present(CHILD_ID, S_MOTION); } boolean pinstate = false; void loop() { boolean newstate = (digitalRead(MOTION_SENSOR_PIN) == HIGH); if (newstate != pinstate) { if (newstate == true) { send(msg.set("1")); Serial.println("Motion Started"); pinstate = newstate; } else { send(msg.set("0")); Serial.println("Motion Stopped"); pinstate = newstate; } } }

@Vertorix said in Vertorix - Easily Create your Own Mesh Network with Sensors and Controllers: Hi I have created a new IOT project which allows the user to easily create a mesh network of sensors and control End devices. All programming of devices is done in the open source Arduino IDE, and there are already libraries and examples available. It's really easy to make your own network because all the mesh network side is automated. There is no stuffing around with complex wireless libraries, you just take your sensor readings and send them. You can use Node-red to create Dashboards and forward messages to MQTT etc. See Documentation here: link text The VT1100 in sleep mode consumes 7uA, so can run on battery for years. [image: VT1100Side.jpg] I'm trying to gauge interest in the project. If there is enough interest I will sell the devices cheaply. Thanks! thanks my issue has been fixed.

@JohanH - thanks for your reply! I also hope and think people who build commercial products have knowledge of this :) But as a hobbyist, there are two ways to go - either you dont have to care or go bare minimum, if something happens its your own fault, or you can try to make is as safe as possible. My idea was never to make this thread a information source for a commercial product. I wanted to try to make my own products as safe as possible since I have children around. With that in mind, i want to be on the safe side of things so some things i use from here might be exaggerated. But my PCB (HLK-PM01 breakout) is working great, and I feel safe. I have had it outdoors (under roof covered in IP5* box, -20 to +30 aprox) and its been working for me for a couple of years now. Better than I had before, when i just stripped an old fake samsung charger. /Andreas

I know it's a bit late reply xd. You could watch Ben Eater on YouTube. He has build a breadboard computer and explains how it works. He explains it great.

Hi, By the PCB silk I was wrongly thinking that the module could be on of "RFM69" or "RFM69H" or "RFM69W" and "RFM69HW". Now if I understood correctly the diagram, the module can only be either the "RFM69W" (low power 13dBm) or the "RFM69HW" (high power 20dBm). Since this module has the "H" marked it should be "RFM69HW" and that is confirmed by the other side of it, because it has the two additional black ICs. Thanks!
