No I have not tried at all and I am not even considering trying. After purchasing this new and getting it running I was consistently getting warnings that my ammonia readings were borderline but no other test I was using detected any ammonia. After contacting them and discussing my options their only advice was to pay 40 dollars to ship it back for calibration on a 20 day old device. Then two weeks later they pushed a firmware update that broke the Virtual hub.
This device is a cheap par meter at best IMO, if that's all you want it for is to baseline some PAR readings it isn't a terrible investment but other than that the device is junk.
