My Project

Impressive @Kokosnoot!

I may misunderstand how they work, but I've had the idea that (super)caps are better in short term high current situations. Like regenerative brakes for robot lawnmowers, not slow drain low power devices. It sounds to me like the life boat is the lifepo4 batteries. I'm all for experiments, so please dont stop, but unless the environmental conditions are intolerable for the batteries, I'd say you found your answer.

what I meant is that they don't actually go to 0v even if you short them as you will always be able to measure some small voltage. I am no expert but my bet is that that 0.5/0.6v is kind of their bottom line where they don't hold any more useful energy below that. For balancing there are SAB Mosfets that help to keep all the supercaps on the same voltage, but the reverse charge issue is the same for all series circuits, also LiPo worn out batteries can get to 0V and then getting reverse charged with all the consequent risk of fire.

@thucar thanks :) ill check it out :)

Hello Stefaan, Thanks for sharing your nice project ! How is it with the automatic door and your MySensors controller after 2 years ? Do you improved the code in the meanwhile and do you want to share it again ? I made also an automatic (horizontal sliding) door on my coop with a barebone Arduino and a LDR as sensor, but I want the same functionalities like yours, so I ordered today all the extra necessary parts.

@zrom69 sorry for the delay! This is because I was using the development version of NodeManager available at https://github.com/mysensors/NodeManager/tree/development where SensorMQ implementation has been completely reviewed. Sorry for not making it clear!

@sm_ali You can have a look at this lib here https://raw.githubusercontent.com/DFRobot/DFRobot_BME680/master/bme680.c there is code that handles the calib thing

@itbeyond Hi David, thanks for the code. I have an issue with the transformer as it get very hot, and am trying to use the same arduino to control another relay to turn on the tranformer before irrigation and turn the relay off after finishing the irrigation. Please, will appreciate your help pointing out what changes to the code are needed. I was trying to use an analogic pin as digital but am having unexpected results... pinout(A0, OUTPUT); digitalWrite(A0, HIGH); Thanks for any help.

@annujbhatia , did you manage to connect it right? I have the same challenge as I have 9 zones. https://www.arduino.cc/en/Tutorial/ShiftOut should be the guidance I suppose

I want to use this mysensors touch sensor to adjust a selector switch in domoticz, so if I select scene 1 the selector switch in Domoticz goes to 10%, and scene 2 to 20% and so on. Is that possible and how do I do that?

@dbemowsk Any progress I want to do this as well?

@litunbls This forum is Arduino only really... Search the web or convert an Arduino library so it can be compiled in Keil.

@mfalkvidd Gland plugs are almost bulletproof, perfect for the selected diameter. The beauty of the free grommets usually accompanying cases is that they may be cut to size, whether that is an antenna or a cable conduit...

you could also provide the links on eBay of the pieces

checking it out now :)

Welcome to the MySensors community @shaukat59 MySensors does not support mesh networking. Building something using http://www.airspayce.com/mikem/arduino/RadioHead/classRHMesh.html is probably one of the leeast hard ways to do what you want.
