I have Some of these left over. They are plug-and-play for Raspberry Pi 2, 3 and 4. And they run out of the box with the MySensors gateway software for Raspberry Pi.
Please let me know if you are interested in one.
@ben999 said in Raspberry as a node (bis):
Does it stay local within the LAN (and gets directly to my gateway) or does it have to travel through internet up to openhab and down again to my gateway (remember, my bell has to ring) ?
You run an MQTT broker ('server') somewhere in your local network (or even on your pi) that takes care of distributing the data.
Not saying you need MQTT, only that it works marvellous for me.
So last question just to be sure : it is not common practice to use RPi as a node ? And there is no "sketch" ready made that can be tweaked ?
Not to my knowledge, but as all platforms supported by mysensors can be turned into nodes, this should also work for a pi.
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.

Is there something I could help to spped up merging STM32duinoUpdate branch into master ?
At the moment I have couple of blue pill boards (STM32F103C8) and want to test RS485 network with MySensors.
And that I have one question, Is it possible to use two hardware serial ports - one for rs485 and another for debug prints ? What I tried is:
using AltSoftSerial for rs485 but STM32 platform is not supported there
using #define MY_RS485_HWSERIAL Serial1 and #define MY_DEBUGDEVICE Serial2 but Serial2 does not exist
using SoftwareSerial but it seems that the code hangs somwhere and does not even get into setup() function (SoftwareSerial uses some timers so maybe they interferre with MySensors)
Hi, I found this post after trying to find designs for building a configurable forward/reverse phase dimmer controlled by ESP32.
Has anybody by chance put the previous post in production, i.e. allowing for fully isolated use?
Alternatively, are there other controllers like the FL5150 that can be controlled deterministically via e.g. I2C, PWM, etc.?
Just a quick thought, but would it be preferable to attach something like this to the PCB using connections for current measurement rather than the ACS chip?
Modules have the benefit of being optional, so you can skip them if you don't want them on a certain channel. In other words, it is conceivable to have 4 out of 5 channels that report and 1 that doesn't, for example.
Because the cost of the module and chip are same, I don't believe there is any difference from a financial standpoint.
