Hardware

@nagelc Thaaaanks! Your answer is valuable to anyone.

@LastSamurai, Very nice project you have here! Thank you for taking the time to post/share your work! At first I thought it might be exactly what I was looking for, but reading through everything now I am not so sure. I have been studying various ways (Wi-Fi, 433/315 Mhz RF, MySensors) to implement controlling RGB lights and I initially thought Wi-Fi (while readily available, easy, and cheap) might be too "slow" in response time, which got me thinking to use MySensors (with NRF24) instead, which led me to this thread (among others). Something concerned me though, I see in your GitHub for this project you stated: Project frozen/final - This project is done from my side. It has been working for years but I switched to another solution so I won't update this anymore. and on your OpenHardware page: Update2: They have been running for about 2 years now mostly without problems. The only disadvantage is that my Mysensors network overall is quite "slow" (~1s reaction time). I am currently experimenting with Wifi RGBWW controllers (H801) so there wont be to many more updates to this project Which made me want to ask you what you are using now? It seems to me that those MagicHome type Wi-Fi (or RF) RGB controllers would be pretty hard to beat price wise, I don't think I could implement similar functionality (including packaging, etc.) for the same amount of money, and that's before even counting my time. Also I am still struggling with reliability of my MySensors network in general, but I hope to be able to still solve this as it seems that many others have been able to (but that is a different subject altogether).

@secantscope I understand - It is a few years since I looked into this and then the only conclusion I could make was to take a meter and interface with usb. It would be more work and my needs case didn't warrant that at the time. I am sorry I could not be of more help in this, but it just seems to be the way things have been for a while. Maybe in the future things will change. As @nagelc suggested a lesser sensor could be used and you could calibrate it yourself. Seems little other options really. (Now I said that you just wait for a killer posting with just the thing you want linked) !!! ;)

Thanks a lot for sharing your experience I had reached a similar conclusion I tried to put in the oven the modules that failed, but only a few were "fixed" I have already successfully used another type of modules mounted in China at a lower price than the individual components, and I assumed that they could reach that price because they manufactured millions of modules But in the case of the GY-521 it seems to be of very poor quality, it struck me that I did not find any comments on forums about these bad modules I am evaluating redoing my PCB to directly mount the original MPU6050 Thanks again for your help

@Beeblebrox666 you can use them just like any other strip, with the limitation that not all leds can be controlled individually.

@tbowmo said in Laundry sensors: Just need to make something durable so that the sensor isn't destroyed if someone decides to overfill the basket, and force the drawer in. You just need to put it recessed inside an enclosure, it doesn't need a very wide aperture. For using above the table except if you have a low ceiling it won't do the job properly, in theory it's up to 2m but with daylight I couldn't detect non-reflective things further than 1m. If you have a relatively dark room you can measure further but it must be dark with a very reflective surface to really reach the claimed 2m. There's a VL53L1X with twice the range that is more expensive (close to 10$ with shipping it seems) and that will likely use way more power. I've never tried it, but I think I will soon as I really want to buy one now :D

@ashokgowtham No, there is no available parameters like RSSI in NRF24. I've just done repeating tests like opening/closing a switch with ack enable in the same conditions for the different throughputs. And after three weeks of use, i can confirm that I've no errors at all at 2Mbps. As i said this throughput improve transmissions with a lot of wifi interferences around.

Radar doesn't go through metal, so aluminium foil should already do the trick

Switch to tantalum if you have space, much better for battery powered as a decoupling cap, low leakage. Choose a cap with voltage 3x to 4x of input voltage.

I have now been running the gateway for more than half a year, and unfortunately the gateway runs regularly (about once every 2 weeks), so I am going to replace the gateway for a W5100 ethernet adapter. I used it in a second gateway, and this gateway is stable, I haven't had any crashes in about 4 months.

@ayo I have this problem too, I can't get the radio modules work, the modules are nRF24L01 and I have tested with two arduino nano and two Arduino mega2560, but there is no result. The transmitter and receiver can not contact each other.

A really impressive project based with DIN interface. Do you also integrate in DIN format the system to put a mysensors controller as well such as a RPi , etc... ?

@yveaux In my outdoor tempsensor everything was working for a while. And to avoid any problems with the initial setup I put a Nano on a breadboard with only the nrf24 connected. The first setup could have had some issues that I don’t know of, but strange that my test setup have the same problems? That should have avoided any hidden problems to test everything again in a new setup. And Arduino runs on 5V and nrf24 on 3.3V. Is there any other way to check the function of a nrf24? Maybe some other sketch that is not mysensor but able to verify the nrf24 works. I need to try to narrow down the problem because it seems strange that all 4 are broken.

@sweetpants :+1: Thanks for the positive feedback.

@neverdie ASR6501 M0 with sx1262

IIrc, in the USA, the frequency hopping would make the 27dbm legal. Otherwise not. In answer to your question, the higher priced module above claims to do fec. Although I think it's normally done at the phy layer, which they aren't . Maybe if you turned off crc and did promiscuous Rx....
