Not sure. Haven't heard from @John in a while.

No updates on the pidome site for more than 2 years now, so guess this is no longer active?

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.

When using BME280 breakout https://lowpowerlab.com/shop/product/185 with Embedded Adventures library, life is easier if addrBME280 is set to 0x77 (it is set to 0x76 in BME280_MOD-1022.h)

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.

What's the expected value range for this sensor in the evening with some lights on? It's not dark here atm but I am getting ca 10 lux only. Any ideas?

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

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
