    @alex28, Feedback from new people is valuable! New people have a different perspective than those who have been here a long time, and have grown with the platform (or watched it grow up around them). We should never forget that, all of us. Personally, when I am learning some new software or something for the first time, I always try to give my fresh perspective as a new user (assuming it is F/LOSS; I absolutely refuse to commit a single ounce of my time/energy/money otherwise), help to update docs, or whatever (as much as possible). Having said that, this is a tinkering platform. On the bell curve of HA stuff, we are at the far right; the smallest number of people and most difficult, requiring the most knowledge (short of making things from absolute scratch). This is not off the shelf, ready to go stuff. This is building your own custom sensors from modules and components, nearly from scratch. If there is one thing I think we (as a community) can do better, it would be to make this more clear up front. I just looked at my profile page, it says I joined "23 Mar 2016." I'm pretty sure I started reading / studying even before that. But right from the beginning, I fell in deeply in love with what I saw, even if the vast majority of it was all way beyond me at that point. Actually now that I think about it, I have had interest in HA stuff since our first X-10 modules I remember playing with as a child to turn on the outside Christmas lights, and the electric "candle" in the garage... I thought that was just the coolest thing ever! :smiley: Every so many years during my 20s and 30s, I would check back in on the HA situation again but it was always the same story: very over priced devices that could not talk to one another. Until I came across MySensors! We are actually living in wonderful times right now if you are a fledgling hacker; boatloads of information available on the Internet, inexpensive parts, and an explosion in Free / Libre Open Source Software (and increasingly, Hardware!). Eventually I bought some parts, made a couple attempts, got some stuff working, but it was unreliable. I was in over my head. No time to spend on the stuff for months, years at a clip. But I kept reading, and reading... I finally had my first real success with nRF24L01+ just a few days ago (I like to think I give some good tips in that post about initial radio setup and testing, which IMHO should be linked from the Troubleshooting post / page; I would also be happy to adapt to a wiki / doc page or whatever). It has been a very long road for me, but I kept coming back... and the success was very sweet when it finally came! And now I know how to build and maintain my very own custom sensors, and the sky is the limit! By the way, I disagree with those who say nRF24L01+ are not worth it. But maybe I have just had good luck (now that I know how to test, position, etc.). Great, inexpensive little radios. I bought mine right off AliExpress, 2 x 10 pack of them IIRC... One thing that kept me going in the meantime was having some successes along the way. At one point I must confess to giving up and I ordered a bunch of cheap 433mhz stuff. It works great! I still use it. If I hadn't done that though, I may have given up completely. But it was enough to keep the flame of HA alive. The Tasmota / ESPxxxx stuff is similarly much "easier" to get started with, tradeoff being it uses Wi-Fi of course. But MySensors is for when you outgrow those sort of "off the shelf" solutions. And then you use something like OpenHAB (or whatever you prefer) to tie it all together seamlessly. Speaking of OpenHAB, that is another complicated and famously high learning curve thing. Difference is, over there, they are very up front (in forums anyway) about that. They will tell you outright that you are creating a bespoke HA system. It is going to be a lot of work, learning, trial and error, etc. Back to the case of MySensors here, we are talking about tying together many disciplines from radio propagation, to electronics, to programming, etc... One other difference between OpenHAB and MySensors that I personally perceive is that they have a bigger and more active community perhaps. At least on the forums, which are very active and you almost immediately get questions answered (I have come across a number of unanswered questions here while searching around). They are relentless about updating docs (they also make it easier for everyone to do so, more on that below). The MySensors devs are great and have shared this wonderful platform they have made with the world. But by now I think the community, docs, whatever maybe have not kept pace with the growth of the platform and new users? Maybe that is where we should concentrate our collective effort? @Yveaux said in Started with MySensors and about to give up (some feedback): we are currently discussing behind the scenes if/how we can let users edit the documentation pages I'm actually surprised this isn't the norm. Let's remove friction here; many hands make light work! As I alluded to above, they make this super easy at OpenHAB. Every page has a link to "Edit this page on GitHub" where you don't even need to submit a PR or anything. They make it very easy. It would be great if we could move more towards something like this. I bet anyone who cared enough to reply to this thread (and has the time to do so) would probably even pitch in a bit to help out in that department, so the small handful of you devs don't get burnt out trying to keep up with everything yourselves...

    It's kind of a hassle wasting 5 minutes, 2 - 3 times per day waiting on the gate to open, and the LONG wait for it to close just to make sure nobody sneaked in... :blush: Looking at fitting a cantilevered sliding gate here so it traverses the -20 ice and snow (no bottom rail), but will be opening and closing it manually as it's way faster.. Plenty of manufacturers of gates depending on your locale, most of the kit here seems to be rebranded turkish, italian or chinese origin, but as sliding gates are usually driven by a fixed motor on a castellated rail they are slower than the hinged manual gates I already have. ;) And no remotes to fumble for...

    @alex28 yes exactly, it may look exagerated but this is how it works. Same if you would replace the original wifi antenna on a commercial product. Like I said many times above, development boards (like OP design) can maybe fit in the "subassemblies" group, so mostly for development purposes only. CE is less strict regarding the process. That's a while I looked at this, way before debating..Personally, I completely don't mind what people do, that's not my business. I just mentioned regulations as infos for those who are interested to know more. that's all. more links here: https://www.sparkfun.com/tutorials/398 https://forums.adafruit.com/viewtopic.php?t=113747

    @jocke4u I run 2 RF gateways and it's not a problem. When you 'migrate' a node to a new gateway make sure to run the mysensors clear eeprom sketch first to get rid of the old routing table or you might have issues.

    @GLAB No worries, was in a similar situation.. My perspective was on what the Node could be made to provide, not what could be done within Domoticz to address the requirement - eg Had heard of Dummy counters but had no experience nor understood their purpose, nor had ever used scripts. I had been sending a logical ON/OFF as well as a cumulative total from the Node and hit the same hair-pulling scenario as yourself. Now only the ON/OFF is sent and the short script makes the transposition within Domoticz to a dummy meter (I think kWhr) using the internal clock in Domoticz. Have fun ;)

    @NeverDie I can give my thoughts here, and we can move it later to another thread if necessary. The bigger selling points, at least for me: Every project is a self contained directory, even the boards configuration, bootloaders, libraries, code and build procedure I have a project template for mysensors (mainly a platform.ini) that I copy for each node that I create. I can manage everything with my known tools (vim, make, git, etc) I like to play with arduino and electronics, but have other interests (Family, friends and 3 small kids...) so I usually have little time to spent in my hobbies. Platformio allows me to just have all the configuration in code and know 6 months ahead that I can do a "make clean && make upload" for a particular node without issues, even if I lost my PC, as everything is in my gitlab account. Also the FW of my 3dprinter must be complied and uploaded with platformio (marlin 2.0) so I can have only one tool for both hobbies.

    I'd have a look at Candle. Lots of people are building it, and it's based on MySensors.

    @tbowmo Agreed, creating a Slack when there has been an IRC channel since Mar 18 2014 was probably not a great idea.

    @Yveaux Thanks for the pointer, I will take a good look at that. What I need is something light that won't have a growing variable. I thought of using an array as the best option, but I will vertainly look at what you have found. Thank you!

    @jamzm what are you looking for in particular? I use a ProMini with the Door/Window/Button switch. The sketch is modified to always sleep and wake up on change. (https://www.mysensors.org/build/binary), with a reed switch (https://www.aliexpress.com/item/32468849883.html?spm=a2g0s.9042311.0.0.27424c4dYn4UwZ) The sensor is powered with two AAA batteries. The case is actually from a real door/alarm system from aliexpress which I first wanted to hack but then decided to strip the electrnics out and build it myself. I use a NC reed switch to save additional power (when door is closed mainly). If you are interested more in the other part of my answer, I use OpenHAB as a controller. I have extensive rules to react base on an "uncontrolled" opening of a door or window. This could be anything from turning lights on to send an email to your phone, triggering an external security company or enabling your sprinkler ;-)

    Reporting back: Testing some cheap aliexpress 3mm red or yellow through-hole LED's, I found they required around 10ua to have decent visibility. Other LEDs that I got from amazon required several hundred microamps to be equally visible. However, running this 25 cent CREE green LED at 1ua at around 2.5v was sufficient to be dimly visible: https://www.mouser.com/ProductDetail/941-C503BGASCB0F0792 Even 500na was enough, though at less than that it becomes dodgy. Part of the credit goes to narrowly focused optics. Also, 10ms was enough. So, 1ua at 1Hz with a 1% duty cycle means just 10na on average. Not bad! The pulsing actually makes it easier to see than it just being constantly turned on, I presume because of better contrast. I haven't yet tried it at night, but so far this is already better than what I was expecting a priori. Putting it at the bottom of a black tube might also be interesting to try: you'd get improved contrast, and with the narrow optics maybe little light would be sacrificed to the blackness of the tube Anyone here found an LED that's more efficient than this one? Or is this already about as good as it's likely to get?

    @sghazagh When seraching for this file on google, I come across this hit: https://stackoverflow.com/questions/61029226/how-do-i-install-libraries-for-stropts-h It states stropts.h is deprecated, and apparently the gateway doesn't use it, only includes it. Could you file a bug report here to remove this include please?
