EEPROM lifespan?

Hi, Does anyone know what the expected lifespan of the EEPROM is? I am reading in other foras that an EEPROM has a lifespan of about 100.000 write cycles as a rule of thumb. What speaks against this number is the the following example: https://z-uno.z-wave.me/examples/Water-Meter/ The water meter in...

Re: Electricity meter using ZUNO_METER

Hi, I am in the process of building an electricity meter which reads the light pulses on the "official meter". I am not completely done yet. I have the HW and the program logic ready and tested. It is stable and has been running for a while. BUT, I have not yet connected the z-uno to the z-wave cont...

Z-Uno hangs and unhangs

Hi, I have built a sketch which has worked just fine for weeks, but after I tried to "upgrade" the code to store some data in EEPROM, the code makes the Z-Uno hang for hours before it comes alive. I am at a loss in understanding why this is the case. Here is what I did: 1. Ver 1 of the sketch works ...

Re: Scene control not working

Still not working for me despite setting "S" instead of "M" in the associations settings. My zuno sketch defines 10 scenes (0-9) but when I try to program a block scene in HC2 there is only one scene-id to choose from. Actually, "Scene id" in zuno translates to "KeyId" in a HC2 block scene. And to c...

Re: Housing for Z-Uno Shield

Thanks, makes sense that the signal is blocked quite severly. Forgive my ignorance when it comes to antennas. For the European freqency (868,4 MHz) it would mean a 17,3 or 8,6 cm antenna I think. Would it work if I just connect a cable between the antenna socket on the Z-Uno board and the metal encl...

@schmidmi:
Tell me, how did you solve it?
For me it's only working intermittantly.

Unstable power from the Z-uno?

Hi, Wanted to check with the community if you have encountered the same as I have: unstable output from the Z-uno when driven by USB power supply. I am doing a small project similar to the example project "IR to Z-Wave": https://z-uno.z-wave.me/examples/IR2ZWave/ My TSOP 7000 sensor prefers 5V so I ...

Re: Housing for Z-Uno Shield

I am taking the opportunity to ask the forum if anyone has tried to put the Z-Uno inside a metal enclosure.

How does aluminium or other metal affect the z-wave network range?

Here is one in aluminium as an example: https://uk.rs-online.com/web/p/general- ... s/5287044/

Re: OTA Sketch Upgrade

Not a solution to your problem, but as a comment to OTA update of sketches: I just put the question to Fibaro how to make use of the OTA mechanism in their Home Center 2 controller for us developers. Their response is that it is not possible because they only support OTA for their own products. It i...
