MIYO Smart Garden Shop Reviews 

I received the unit and in theory was working fine, but if you don't have direct sunlight pointing at the device for several hours, you run out of battery making the device unusable. You cannot charge it through a cable, nor with rechargeable batteries like other solutions like Eve Aqua do.
I have the water connection under a shed where sunlight is very scarce, so unfortunately this limited the whole utilization of the product.
If the product would like to launch a v2, I would expect them to "copy with pride" all of what the best solutions in the market already have, and then add on top a good chunk of innovation. Apple Home Kit compatibility is a must nowadays.

Acquired the product 1 year ago for it's innovation; automatic and efficient watering control of the garden, accessible from any place through internet. The App had its bugs but acceptable for a recent product. Besides that it worked OK, though sometimes the connection between the cube and the sensor goes down, even if they are not far from each other. Recently, we've noticed that the soil humidity sensor is showing signs of degradation, namely the chip sensor seems to be detaching from the support. This suggest that it's not very robust and shoudlbe improved. Nevertheless, contacted Viratec to claim replacement of the soil sensor under warranty, but never got a reply. Fortunately, as acquired through Amazon, when I informed them that Viratec was not responding they fully refunded the paid amount for the full set, which was then shipped back to Amazon. Naturally did not buy a new Myo set, rather chose another well known brand.
