Re: Z-UNO based weather Station (German description)

Thanks for the update... I have not tried this yet, but I have found how to get 0.11 Lux in the lowest range and 100.000 Lux high range. The trick is, to modify the "measurement time registers" of the BH1750 https://gist.github.com/Koepel/b70f81c71a52d8d6d3da86b9fe56d50e Since you mentioned the high...

Re: FLiRS - flapping digital pins after wakeup

Quick update... A bit more detail in the ZM5202 datasheet... But this does not explain the "flapping"...

"Some reset methods deliberately leave the state of GPIO pins unchanged, while other GPIO pins are set to high impedance with an internal
pull-up."

Re: FLiRS - flapping digital pins after wakeup

Ah, yes, I see what you mean! I wasn't clear when I said "default to weak pull up". My bad. That is assuming only the hardware reset! I fully agree with you, Either the Z-Uno or the framework does extra initialisation, I observed what you said when I wrote my sketch, but I do not remember the detail...

Re: IRcontroller parameters

(...) The interrupt handler seems to stop the Z-Uno from executing some time consuming instructions, like the Serial.print command for instance. Some background info... According to the official docs : "The duration of an application interrupt routine must be below 80us." (See INS13954 Z-Wave 500 S...

Re: FLiRS - flapping digital pins after wakeup

Almost all MCUs based on 8051 default to "weak pull up" and I think the Z-Uno is no exception to that rule. I occasionally program STC MCUs and they exhibit the same behaviour. In any case, one of the guys of Z-Uno confirmed there is no workaround. I have build an RGBW and the gates of the LED drive...

Re: Z-Wave Gateway

By gateway you mean "controller", like Z-Way or Fibaro HomeCenter? Z-Uno is for developing devices, not controllers. Though, for sake of completeness, you might be able to turn a Z-Uno into a controller by flashing it with the published generic image (in the Silabs SDK), but there might be no way ba...

Re: [solved] FLiRS - zunoSetBeamCountWU() question

Thanks for the feedback. Indeed, there are 2 issues with sleep: pin state and NZRAM. Have fun with your Z-Uno!

Re: Z-UNO based weather Station (German description)

Regarding BH1750: it supports 0.5, 1 and 4 Lux resolution... With 4 Lux resolution you should be able to get higher values than 32k, but then it is not very sensitive in dark light. So Ideally, you'd have to measure at 4 Lux resolution, then if it is below 16.000 switch to 1 Lux resolution. I am not...

Re: FLiRS - zunoSetBeamCountWU() question

I wrote this sketch some time ago: https://github.com/petergebruers/Z-Uno-FLiRS-LED-DEMO And I noted: "If you notice an unexpected "blink" of the LED, this is "by design". The Z-Uno initializes the pins, and it takes some time to get the LED pin back to output. The only way I can think of, to avoid ...

Silabs publishes Z-Wave SDK, extra documentation, sniffer and PC controller and gateway

This is great news for all technically inclined! After partial release by Sigma, last year, the new owner "Silabs" decided to publish a lot more useful stuff: See this excellent post by Mr "tinman" on the fibaro forum, to get you started. (Note, I'm involved in that discussion as well... so I might ...
