My Project

@kimot said in My experiences with MySensors: And for "MESH" topology. Arduino "painlessMesh" library for ESPs exists WIll have a look at that too in the near future. Thanks for hinting me towards this. Boozz

When you get trained you can pimp up the guitars like the one in this video, it's based on a nano :D https://www.youtube.com/watch?v=4vkzY3U7qts

@mfalkvidd Thank you for your answer. I will give it a try for this price.

Not sure if it helps. I find this drop/tilt/vibration sensor https://bit.ly/2kZrZnV. And my personal advice is that you buy your dad a emergency watch with built-in heart rate detector. It would help a lot i think

@simbo said in Air particulate / dust sensor node: The PMS7003 module is physically a bit of a pain as the intake / exhaust ports are on the same side as the connector If you are making a PCB you should take that opportunity to put a female header (1.27mm spacing) on it and plug the PMS7003 directly on the PCB: no adapter, no cable needed.

@jasxvii Have a vague memory of coming across this error and found it linked to the library MyConfig being called, but as I went with a different sketch for that particular project did not investigate further. @mfalkvidd has considerably greater insight on the sequence of library calls, perhaps posting the sketch might help.

There are several solutions for this kind of water reading but all are lacking something for my needs. I've been seeking for a solution which would combine best parts of different projects: https://github.com/ecsfang/WaterMeter accuracy of 0,125 litres by reading only 1 liter dial with 8 trigger points. Easy and this data would be sufficient combined with time stamps. https://github.com/jomjol/water-meter-measurement-system ESP32-CAM as camera and server running the OCR would be a lot cheaper than raspberry system. Usually someone building these have the server and really I wouldn't have any other needs for the Raspberry. Also this could be integrated ESPHome etc.? So it would be out of the box type design for ie. Home Assistant... https://olammi.iki.fi/sw/dialEye/ Possibility to define any IP web camera as source But I'm not any good at programming or coding... I'm not even sure if I describe my wishes correctly, please pardon me. Would I find someone interested enough to combine these three solutions? TL;DR water meter solution development request: 1 liter dial OCR with 8 trigger points ESP to server and server OCR software (prefer Ubuntu systems) MQTT publish and/or Home assistant compatibility via ESPhome or similar systems? Willing to throw in a coffee/beer or two for this matter... Regards, Matti

@jesus-cataluña Hi great work! Any chance for your sketch? There isn't many working sketches (without many errors in log) for home assistant. Unfortunately I can't write code.

@mfalkvidd Thank you the components just delivered some parts are still on delivery but i wanna ask the gateway thing on the smart plug i wish you can help me find a link where i can access it

@flopp Found one mistake. I wrote some Serial.print to see where in the code my problem was and I wrote in a wrong place, so the code was looping on a wrong way. When that was corrected I found out that my relay needed to get 1 when it was off, so I just changed to below and now I don't get a green light as soon as I power on the arduino #define RELAY_ON 0 #define RELAY_OFF 1

@nagelc Just ordered one of those buck converters from Digikey. Thanks for the suggestion. That might fix my whole issue.

@nca78 If you're talking about the basic motion sketch - I've tried it and it doesn't work The node checks in when initially powered but i can't seem to trigger it...

MySensors supports Lora (RFM95), so you could have the devices talk to a controller at home. As a controller I recommend the Mozilla WebThings Gateway :-) Less manual tinkering with config files. And yes, communicating with each other without a parent gateway is also perfectly possible. How about using sensors that are more robust than ultrasonic? There are some sensors used non-contact detection of water/gas levels, for example. if you want some GSM code, give me a shout.

Hi there! I have been doing some electronics and here is my thoughts about how to connect things. Any help will be very welcomed. My idea is to create a PCB after testing everything on a breadboard. [image: 1564422473670-irrigationmys-resized.png] [image: 1564422345375-hbridge-resized.png]!
