General Discussion

@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.

no. bluetooth is not secured by default. you need to handle this in your ble fw

@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.

I have LSC Smart door sensor, it works great. Now I can't imagine my life without smart technologies.

@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!

@bjacobse I agree - when I was putting mine together I could see the desk top. But now it is in constant use 'building' I never know what I will find underneath something!

@BearWithBeard thanks - that is useful to know. I will try again with this soon, but today is another project! ;)

@mfalkvidd Got it! Had to put on top of sketch to get it to work.. 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 ;-)

Or was the valve type RA :/ That has z-wave actuator

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?

Is this possible?

Thank you @dzjr I am not sure how it happened, but I am also very happy of the pleasant and supportive tone on the forum.
