Interesting idea, as far as very good - fast defective miserable Service

Installation and operation are very simple. The sensor communicates via Bluetooth with the free app on the iPad, for example, the iPad again with the flowers database on the Internet. In the app, there is then also useful care instructions to flowers (whether monitored by sensor or not). After 24 hours, the sensor has sufficient data collected and from that time he logs on a regular basis with information (if required). In the app you have the current state of water, fertilizer, light and temperature, as well as an evaluation of the past few days / weeks / months.
We'll see if the digital green thumb nourishes the flowers better ;-)
We tried it at a Yucca in the first result was the de flower too much fertilizer had (so rinse with water) and it will also wetter than we would have expected. The too little sunlight is there, more is not surprising. Here to be seen whether the growth periods are taken into account, ie in winter other settings than in summer.
Otherwise, the phone makes a very neat and thoughtful impression.

Addendum: defective after three weeks, no synchronization possible in the aid is 'Contact Customer Service' delivered. This however does not respond to email. Presumably, the fee on the telephone hotline also want to earn more.

Conclusion: Stay away, do not mature.

Update:
After some time I was but then contacted by Parrot and replaced the unit. Even this had to be replaced after a further 4 weeks. Since then it works.
One can argue about the benefits. The display respect. Fertilizer we dare not really. We also have plants with Semiramis Instead normal potting compost. Again, we do not quite believe the messages.
It remains primarily the water display in handy
Nevertheless, since our plants are in better condition, whether because of the sensor or (presumably) by the conscious use, definitely they thrive now.
