Once I decided to power the HX711 externally rather than through the solar node, it has turned out to be a nice little current monitor. Typical charging currents for indoor solar nodes that are far from windows is only around 50ua, and the HX711 seems good enough for monitoring charge currents at around that amount. Thanks @AWI for posting the project!

@Yveaux You board is almost perfect. You could just expose some of the pins with the next version. This would keep it very generic anf make it easy to add additional functions. Commercial devices contain temp, hum and light sensors. And a vibration sensor as thief protection. Most of that could easily fit in the molgan.

@gohan I tried. Unfortunately, it didn't seem to matter with either or both those changes

PIN as Ground http://arduino.stackexchange.com/questions/620/a-digital-i-o-pin-as-ground

@AWI I've made similar project but using RS485 and modbus for communication. Now I'm porting it into mysensors. In my project I've light sensor to lower fan revs during night (because of noise). I will try to post my sketch when I finish it.

@ross-shirer Thanks for bring this topic alive as I had not seen this before and it was just what i was looking for the basis of another project. I have thrown together a quick test node and it is working all fine with openHAB. The instructions for use are included within the program Summary block. 1. A local database with Card id's is kept in the node. Card id 0 is the "master master" card. With the master card you can: - Open the door lock (just present it) - Include other cards (present it twice and present the new card) - Delete cards (present it three times, present the card to be deleted and confirm with master card) - Browse the cards (present it four times), the display shows the card indexes with their status. So the MasterCard is needed to enable the other cards. Swipe the master card twice and then swipe the new card. Remember to comment the eprom clear command after first run otherwise the non MasterCard data will be lost on reboot. As i did not do that at first, so caused a few minutes delay. //cardDB.initDB(); // ONLY in the first run to clear the EEPROM store (comment later) Working fine for me with nine cards, tenth card unlocks ok but report status is incorrect. More than ten are not accepted by the program due to EPROM size limits. (time to add serial memory)

@hek thanks! It took us way more than expected to re-architect all the thing but now that is ready, happy with the result so your positive feedback is appreciated Legacy myHouse issue was mainly around extensibility hence this distributed, plugin-based architecture allowing users to package functionalities and/or contents without me doing any change in the core code. And turning it in a cloud-based service (as an option) could be also really easy. But for now the hope is to build a little community around it so to make it evolve further. Just as a starting point

@AWI I have access to the necessary most modules and electronic components in my city . so if you have idea for this told me and i am ready to test .

@AWI This sounds extremely cool. I will try it asap! Thanks for sharing!

@adds666 I'm not sure but I believe Domoticz prresents it's dimmer values in steps from 5 to 100 I believe. It'd about 10 steps. That's why I'm not sure if you can add more patterns. Unless you indeed change it to a percentage. Hope it helps

Hello AWI , is it possible to post the hole example sketch ?

@AWI. I was just thinking the other day I haven't seen you writing for a while. I hope you are making positive progress and nice to see you are back!

Now it is working extremely much better, I have 8 days in a row without any errors. I think this is how it should be.

@heizelmann I'm happy to see that you can appreciate my work as a continuation of the nice job you already did on this thread.

@AWI excellent! I have something looking a bit like this!! I will show you soon, maybe that will give your some ideas btw nice integration

@AffordableTech will think about it... The weatherstation is a succes with everyone who sees it. I guess it bridges the gap between nerdy and the past. I will post a "techie" version in a few minutes. Basically has all the bells and whistles but less fun..

@koen01, really like this cool cube project. Couldn't you add it as a new project on openhardware.io? This enables me to show it on the mysensors.org build pages as well.

-- revisited --- I changed the bootloader to a 8mHz version. As the processor runs 8 times as fast the active period pulse width is now < 0.5 ms (earlier 3.8 ms) The sleep and active consumption have not changed. This would reduce the 'pulse' burden on the coin cell as attentively mentioned by @scalz. Something comparable to 'internal resistance' increases as the charge reduces. This will impact the available voltage for the node. I used a conservative figure for battery capacity (50mAh) and a load current of 0.8uA which will be less if battery voltage goes down. Have three nodes ready for real life test with constant battery measurement. I hope to report just within five years from now

@AWI Thanks for the info. I didn't see the 8 to 6 pin adapter at first. Do

@GertSanders I tried today and now I can download sketch correctly. One strange thing is that I have to open the serial monitor to have the arduino working after the download ... In // I think I have a problem with a bad RFM69 ...

Hello, Some pictures of my scene controller inspired by this post ! I modified the original sketch to have two functions: keyboard for my alarm (from key 1 to 9) and scene controller (from key 10 to 16). Thanks @awi for the idea and the original sketch ! David.

@m26872 The link is helpful and I understand now. Thanks

A version for MySensors 2 is available at https://forum.mysensors.org/topic/4934/wall-mounted-mood-light-v2

@Daniel-Oliveira The periods are in milliseconds... default is one test every 1000 ms. If you want to really test the network set it as low as you want. I have no recommendations. I built it to check if and how the controller handles everything, so speed is less important. The loopdelay is the time between each test vector. So your settings give 10 tests/ second ( = 1 each 100 milliseconds) The SLEEP_TIME (wrong wording, sorry...) is the time if you have more than one test per vector (number of iterations with increment). The SLEEP_TIME is not relevant in the default setting. You have to set the number of iterations in the vector > 1.

@AWI Goodevening Oh better, we definitie have to de that. When does it suit you? Grtz

I just did send(msg2.set(reason.c_str())); and it worked. Thanks @AWI

Re: LCD Clock and Text sensor node with new V_TEXT Hello , I have done the same exercise also with the LCD 4*20 and use the same program. It is great. It works but only I have the first line with the date. The lines 2,3,4 are empty. In Domoticz my V_TEXT are created and filled in. It seems that I can not read correctly the information LCD_line2, LCD_line3,LCD_line4 we can see that on the line READ , the text is V_TEXT but nothing is received. Why ? Thanks

Thanks, I'll install a domoticz again to my NAS Synology... I don't have choice if I want to use V_TEXT... So I don't know how to communique between Jeedom and Domoticz efficiantly, I'll search... Great !...

@Jan-Gatzke Make sure you order the snubberless version, I think it was with a W in the type number. I have now used the BTA24 (without W).

I'm impressed. Nice work.

@AWI I'am user, but only Mac. I use android phone

Haha. Yep, the sun is the reference. Agree, this is a "bug". The problem with the current V_* is that it contains no unit information. A backward compatible solution for this for the 1.5 release would be to introduce a V_LIGHT_LEVEL_LUX. Not pretty but it solves the problem without breaking anything. 2.0 will hopefully solve this without introducing different V_*. https://github.com/henrikekblad/Arduino/blob/development/libraries/MySensors/MyMessage.h#L360 ...and no, I cannot give an estimate when it is out

@AWI said: @David-M. It has limited sensitivity but enough to detect somebody passing by. The plastic cover is not fully transparent... OK. Thanks. I will have to change because in my case, the HC-SR501 does not detect anything

ok found the answer the latest Time.h is only pointing to TimeLib.h so if I am calling TimeLib.h (instead of Time.h) directly it compiles
