Yes, I've noticed a small change in the font as well. We should probably switch to Roboto which is used on the other part of the site.

@kimot Hi Thank you for feedback. I have this issue only with mysensors. it's exactly like you wrote. Hardware tab, present 2 decimals ( for mysensors and espeasy). Device tab, present 1 decimal ( for all sensors), Temperature tab shows 2 decimal for esp easy and JSON updates but 1 decimal for mysensor. Not sure why. Temporary I managed to workaround by using script taking data from Hardware page - child and sending JSON update all started by crone updating dummy sensor. like this: TEMP=`curl -s "http://X.X.X.X:XX/json.htm?type=command&param=mysensorsgetchilds&idx=40&nodeid=0"| awk 'NR>1{print $5}'| sed 's/"//g;s/^.//;s/)//g; s/,//g;/^$/d;s/]//g;' | sed -n '3,2p'` IDX=255 curl -s "http://X.X.X.X:XX/json.htm?type=command&param=udevice&idx=$IDX&nvalue=0&svalue=$TEMP" but for sure this can be workaround by dzVents and JSON handling results but i'm not skilled enough for that Thank you Jakub

Be advised that there seems to be an issue with rfm69HW on the raspberry pi: When using the radio directly on the pi (not as a serial gateway) the range drops significantly: https://github.com/mysensors/MySensors/issues/1367 Apparently this wasn't an issue with mysensors 2.2, so using that is an option if you can compile it for you raspberry pi. ricmail85 created this issue in mysensors/MySensors open RFM69HW issues when sending messages (2.3.1 version) #1367

@stevefury sorry, I don't understand. Which modifications are you referring to?

Hi All, has anyone had any success porting this IR sketch example to work with the IRremoteESP8266 library? I am not getting much further than @korttoma. Thanks CV8R.

Hi I have done search of this thread and no one seems to have mentioned latency. I have a test setup using a LM393 running on a particle photon with a sketch that also runs a flashing led. I have tested this with various led flash lengths and intervals, the highest rate being a 10ms flash with 10ms interval . I have a consistent precise reading of pulse interval and number but have identified that there is a 1ms delay between the flash and the start of the interrupt function. This latency is consistent, whatever the interval between and I can only assume it is a result of latency caused by LM393 and interrupt, though I find it strange that the latency is exactly 1millisecond even when measured in micros. Under low meter loads this discrepancy would most likely go unnoticed but with high loads of 72kWs it results in a significant error when calculating the instant power. Has anyone else noticed this or can give another reason for this that I am missing? A subtraction of the identified latency from the pulse interval reading, calibrates the setup and produces exact readings
