Domoticz

Does anyone know of a USB Lux sensor that just works on a Raspberry Pi with Domoticz or perhaps a 433Mhz one that broadcasts every 1-5 minutes?

Looking to bring it into my system re lighting etc. USB would be easier as I don't have to worry about power and I can poll it rather than wait for a broadcast but either works.

I came across the yoctopuce but think I would need to set it to call a URL on Domoticz that runs a LUA script.
Looking for a slightly easier "find hardware, add switch" before I head down that route

You could simply build yourself the equivalent of that device:
buy a BH1751FVI-PCB and connect via it's I2C to a Raspberry or to an ESP8266.
In first case you have direct read-out by script, and in second case using ESPEasy you get periodic reports over WiFi to your Domoticz at Raspberry.
Cost of this solution is neglectable: just requires time & DIY-effort.

Be aware that the sensor type BH1751FVI according to spec has an upper limit of 65535 Lux (not 100kLux):
without attenuation in midsummer sun the lightlevel may hit the limits.

This is a possibility, would need to work out how to get it into Domoticz, never done anything like that before.
Do you mean the BH1750? If you google that you end up mostly at little boards with the Lux chip on board, the 1751 seems to get me just the chip from what I can make out. Is it new as in people don't sell the ready made boards yet?
