General Discussion

@mfalkvidd that's helped me a lot to better understand what is happening during send! Thanks!

I use a reed switch on my gates - when they are in contact the gate is closed. You could put more at the open points for fully open but I only cared about closed or not. I assumed for 20 secs after they started opening they are opening else they are open. When I close the gate I assume closing until the reed switch shows closed - of course opening the gate during closing will reopen (I also have IR to detect car so gate will not close onto a car).

Another way to get multiple frequencies is to use network based gateways. Check out these projects: https://www.openhardware.io/view/457/Easy-Peasy-Amplified-MySensors-Serial-Gateway https://www.openhardware.io/view/394/Minimalist-LoRa-Ra-01-Shield-for-WeMos-D1-Mini https://www.openhardware.io/view/390/Minimalist-RFM69HCW-Shield-for-Wemos-D1-Mini I have serial gateways for NRF24 and RFM 69, but added a LoRa RA-01 Wemos-D1-Mini with no issues.

Getting closer.. I received a much better 'radar' sensor (the directional one). The only downside is that it has a bright green LED that turns on whenever it detects motion.

@skywatch @mfalkvidd Thank you for your comments. I am using Moteino R4 and RFM69 connected to hardware SPI pins. I tried the same pin with softSPI, but I could not get success. Now I have altered the ADE7763 Arduino library to update SPI settings on every call. And added code to update the only flag on ADE7763 interrupt(like we have in RFM69_new library). Seems all look somewhat ok. I think for RFM69 we use a default clock speed. for ADE7763: SPI_CLOCK_DIV4 Are you using pull up resistors on the CS lines to each device - that might be worth a try too.... Yes, I have

@mfalkvidd Thanks! That is almost the same as my readings. @scalz I have been working few years with ZigBee modules from TI (CC2530). I had dozens of different setups with integrated and also external antenna. RF values was not "just datasheet numbers", if there was written 20dBm output, it was there. But fully agree, that here is the problem mainly caused by non-optimized antenna... So there is a huge space to increase the range of modules... And one more update, whch I think can be very important for all others. My setup is running on OpenHab2 installed on OrangePi Zero with SerialGateway connected over UART. Just now I had realised, that OrangePi makes huge RF noise. If I will run setup normally, receiving sensitivity is very poor. Once I start setup without SD card inside of the system (OrangePi will not start up), Arduino gateway is receiving perfectly. I have just putted SerialGateway to the 50cm long cables, far from OrangePi and usable range is more than twice longer than before. Thans for your time guys. Appreciated. :clap:

I haven't bought anything lately, but saw a good discussion here: https://hackaday.com/2018/09/18/ask-hackaday-hows-that-capacitor-shortage-going/

@neverdie said in Recommendation for PCB fab?: Anyone try this? Sounds like a promising alternative: https://hackaday.com/2018/09/18/get-your-pcbs-made-at-the-mall/ Good idea but it's not really solving much, it's keeping the most annoying parts: using chemicals (can't do it in an appartment building), making the vias by hand.

It seems that I could fix the issue by making the pin 15, LOW at boot time as it triggers the SD BOOT option in ESP8266: void setup() { pinMode(15, OUTPUT); digitalWrite(15,LOW); }

@neverdie said in Windows PopCom tool shows which USB serial ports are available: it must be hidden in plain sight Indeed :-D [image: 1536926095348-c387d1dd-f8f9-4a25-b4de-5e478f88b67d-image-resized.png]

@tbowmo Thx for clarification. As I only use serial GW's, I didn't notice the difference until now.

@ivan-fontanals yes you got it right. The controller can communicate with all MySensors nodes through the gateway. https://www.mysensors.org/about/network has an overview of how the different parts fit together. If anything is unclear, just post a question and we'll try to help.

Would this help? https://forum.mysensors.org/topic/6502/how-to-use-softwareserial-library

High sensitivity: down to -148 dBm. From the datasheet. There probably needs to be some margin, but my experience with Sigfox shows that -130 is quite reliable. After that, packets start go missing. I would guess LoRa is similar.

@neverdie I mean the game. They have everything "nuke" and "atomic".

@jkandasa the gateway is stateless, it has no concept of queue.

@neverdie yes that is the plan

@neverdie yes. Same in latest esp8266 board versions in Arduino IDE.

Hi @mfalkvidd, Problem is, when your code can't compile because you are one (or several) bytes short of ram, nothing else matters. As to readability, I assume you know about that rarely used compiler feature called 'comments'? I hear they use zero Arduino RAM and even less ROM memory. :flushed:. Ok, I'm just being cheeky, so don't flame me, it just seemed a good opportunity for a reminder to everybody. Point being we are all guilty of not using enough comments in our code. You said you are worried about readability and maintainability - it's just like code backups, it's a problem only because we only worry about them 'after' a drive crash, or in the case of comments, two years later when we are trying to remember what the hell this weird code does.. THE REALITY: If we are really worried, we would add liberal comments and do regular backups - otherwise I say we're not really 'that' worried. Cheers, Paul

@pierrot10 1 mm of rain over 1 square meter is 1 liter of water. Correct! One liter makes 358 tips so one tip is then 2,7932 milliliters that is correct. But rainfall mm/hr is 2,7932 * nbr of tips only if the area of the funnel is 1 square meter. Your funnel is only 55 square centimeters so you will only collect 55/10000 of the rain that falls on the whole square meter. The example you are using at the top of your post does not have the size of the funnel anywhere in the code.
