Re: Increase UART Rx buffer
Thanks for answering! Is it possible to increase the buffer a little bit? Is my code looking ok? Do you see any areas of improvement? I mean, shouldn't Z-uno be able to read fast enough from UART Rx without getting dropped packages? It is more likely that I am doing something wrong :-) This is an ex...

Increase UART Rx buffer
Hi! I'm reading power meter data from my power meter (RJ12 P1 port). The meter sends data every 10 seconds. I however think that I lose packets (dropped packets). Data is received at baud rate 115200. I have a feeling that Z-Uno are unable to keep up reading data from the Rx-buffer before it is over...

Re: Hardware interrupt and zunoSendReport()
Hi and thank you. I'm not using "Serial" (only use it while debugging). However I have (after a lot of testing) come to the conclusion that the problem must be related to HW interrupts and zunoSendReport(). After I moved zunoSendReport() from the main loop to the HW interrupt function it i...

Re: Hardware interrupt and zunoSendReport()
Hi again! After some more testing, it feels like it might be a software/interrupt issue. I tried the following. I put some adhesive tape over the IR sensor so that the hardware interrupt wouldn't trigger. Then I put all of it back in place, covering my power meter. Powering the Z-uno via USB (Output...

Re: Hardware interrupt and zunoSendReport()
Hi and thanks for your reply. Would it be sufficient if I power the zuno via USB and use a 0.550 mA power supply? Keep in mind that it is the Zuno and one of these that I'm powering: https://www.mysensors.org/uploads/57c42093071cb0e34c90057e/image/light.jpg I'm also experimenting with the range betw...

Hardware interrupt and zunoSendReport()
Hi, I'm experiencing some intermittent problem with my Zuno. Sometimes Zuno stops reporting my sensor values. I'm powering the Zuno via USB (output 1A). I have started to wonder if the problem has something to do with interrupts... I have an IR-sensor that counts the LED-blinks on my power-meter. Th...

Re: Only get values from one channel (have two channels)
Hi guys, Thanks for your response! I'm using Domoticz and a "Aeotec by Aeon Labs Z-Stick" -USB controller. I think I got it to work setting up the channels like this: ZUNO_SETUP_CHANNELS( ZUNO_SENSOR_MULTILEVEL(ZUNO_SENSOR_MULTILEVEL_TYPE_POWER, SENSOR_MULTILEVEL_SCALE_WATT, SENSOR_MULTILE...

Only get values from one channel (have two channels)
Hi, I'm trying to get the Zuno to work as a sensor with two channels. The sensor reports back power values. Watts and KWh (Kilo watt hours). The problem is that I seem to only get values on one channel. Maybe I'm not setting the channels up correctly? I read something about some issue if you have tw...
