i use the simplest boxes that you find,that suface mount with 4 screws and ruber on door. But be carefull with wall mount screws. if you drill the back of the box ,water come in beind this box. so this ones,the scrfew holes are outside the encosure an box is sealed... another tip is drill on bottom for pass cables but put some neutral silicone. hot glue let water come in with time because expansion coeficient is diferent that the plastic box and open gaps

@Yveaux Thanks! Nice graph. I will do something similar in Grafana. I think my MySensors device should also report every minute, perhaps using the highest sampled value. All values are sent to MQTT by my gateway and my Home Automation will store the time value pairs in influxdb. Right now I'm waiting for the hardware to arrive...

@mfalkvidd Thanks a lot! I just made some tests and it looks promising.

@rmh said in EV Charger (type 2) with RESTful API and Wifi recommendations?: @รอเร-อ btw Normal single phase type 2 charging on an EV is 32a = 7 Kw. If your ev can charge at 22Kw, then it will need a 3 phase supply. OpenEVSE can do this but you will need to put a 3 phase contactor in it. R Thanks a lot. That seems to be exactly what I'm looking for. I didn't order the kit though. I ordered the EmonEVSE WiFi Connected EV Charging Station IEC 60947-5 (Type-2) I'm very excited to get started. Ohh... I'll need an EV too... ha ha

@รอเร-อ @mfalkvidd @berkseo Resurrecting this old thread; I experimented in this PR https://github.com/mysensors/MySensors/pull/1286 by adding a function to MySensors that will allow requesting the time remaining when returning from sleep. Ofcourse this is 0 when returning on timeout, but will be the (approximate) remaining time in ms when wake up was caused by an interrupt. It should be possible to use it like this: #define SLEEP_TIME_MS (60*1000ul) void loop() { // Variable that keeps track of time remaining in one cycle static uint32_t sleepTimeMs = SLEEP_TIME_MS ; // Sleep for the remaining time in the cycle, or when interrupted uint8_t result = sleep(digitalPinToInterrupt(PIN), RISING, sleepTimeMs); // Request how much of the time in the cycle is remaining sleepTimeMs = getSleepRemaining(); if (sleepTimeMs == 0ul) { // Do something smart when SLEEP_TIME_MS has elapsed // ... // Restart the cycle sleepTimeMs = SLEEP_TIME_MS; } } A working example sketch can be found here: https://github.com/mysensors/MySensorsArduinoExamples/blob/master/examples/MotionSensorBatteryReport/MotionSensorBatteryReport.ino

Old topic, but my test shows .304mm per tip. I calculated the surface area as 54.7854cm^2, which is 5cm x 11cm minus the small rounded corners. I slowly poured 60cc water and counted 36 tips. Thus, spread out over the whole surface, I poured 1.09518cm of water, divided by 36 tips equals .3042173mm per tip.

@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

Does adding ack to messages help trigger any failures if something can't deliver? ... well that didn't make much sense. So lets say i have 2 repeaters on my network. i have a sensor that wakes up to report info. it normally goes to repeater1 -> gateway but repeater1 is acting up. Could you tell it to wait for an ack? after X amount of time with no ack would it trigger to find a new parent?

@รอเร-อ Then I suggest you please re-READ, and as I suggested, Google, as Abraham Lincoln once said, "Never believe absolutely everything you read on the Internet". The 5v is irrelevant other than the threshold voltage which registers as a HIGH to it's I2C control. The 3v3 as Master dictates the HIGH as a factor of it's VCC on the I2C bus. THAT is the issue. As Vcc is never absolutely accurate you may strike lucky on a 3v3, there again you might not, your choice... EDIT - To avoid any confusion, what I am referring to here is conventional I2C system. The input HIGH for a 5v is say 0.7 of Vcc, so 3.5v is required on the 5v I2C line to register as a HIGH. Even if a 3.3v Arduino were to put full Vcc on the I2C line it is just below the threshold for the 5v device. That is where the factor I referred to comes in, and I read elsewhere it can be 0.6 but cannot recall which device that referred to. Hopefully that clarifies what I was referring to.

You can buy on LCSC also, I bought a bunch of components there together with PCB (at jlcpcb, same company), price is not as low as AliExpress (and some US components are even more expensive than legit sellers like Arrows) but they have a lot of things at "Chinese price" that you can get all at once. I found a few things like connectors, battery protection IC etc that are hard to find or expensive on Ali/Ebay.

Hmmm.... today I managed to connect this node to gateway. I just rebooted gateway...

@Nca78 I checked the board. Pin 8 IRQ of the NRF24L01+ module is not connected.

@Nca78 said: @รอเรือ said: I decided to test all my 20 sensors and found out that 3 out of 20 actually could power down. Starting the tedious work to un-solder the radios of the remaining sensors now. Using the link in the store, I ordered 30 new from Ebay http://www.ebay.com/itm/400594940658?rmvSB=true This vendor state that their radios will consume 1 uA in sleep mode. I will test all of them at arrival. I believe it's a bit more safe to buy radios on Ebay because it's easy to complain if something shouldn't work as expected. Cheers! Is it too late for you to open a dispute ? With pictures of your multimeter showing current for "normal" module and current for "failing" module + text explanations, it should be possible to get most of your money back. Also, put an evaluation about the radio. If like many people you put many stars before testing the product, you can still add additionnal feedback, that will be useful for the next users who will be tempted to buy from this seller. Hi! Unfortunately I did my review before testing them in sleep mode. I won't do that next time for sure. I will see if I can make an additional review. I have no hope to regain any money from them though. Thanks for the tip.

@hek said: It takes a few failed transmission before it tries to "find new parent". Not sure what happended here without seeing the node log. @mfalkvidd said: @รอเรือ which version are you using? 2.0 has a problem with nodes that go back to sleep too soon after a failed send. This is fixed in the development version. See https://github.com/mysensors/MySensors/pull/558 for details. Thanks guys! Well, I'm on 2.0.0. I'm not the "adventurous type" so I'm not on the development version if You get my point (ha ha). It's good to know that there exists some healing mechanisms in the communication. I might wait for the next stable release or I might build me a dedicated "MySensor : RepeaterNode" with an external antenna to facilitate the communication with my upcoming battery powered nodes in my garden and for the lawn mower that really must be automated soon. Hej tjolahopp! (Cheers!)
