Hi I am looking for a UV Sensor that shows current intensity and accumulated light over time. Does anyone have any suggestions? I was looking at: Grove - UV Sensor, ML8511 and VEML6070.
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.

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.?
@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.

Please do get one - you might be able to help me.
I have tried a blink sketch - that worked. So I uploaded a mysensors sketch that had worked on an arduino pro mini, unmodified (apart from defining ce and cs) and it compiled and uploaded fine.
I built the circuit with 2 buttons using gpio 2 and 3 and the radio on 6,7,8,9 and 10 on a breadboard and fired it up - and nothing.
No output from serial monitor, nothing appeared in home assistant…
Tried a second xiao, same result. Third one failed to upload… so I went to bed.
The sketch worked using the same setup on the arduino so at this stage I’m not sure what to do.
