About the Parrot Flower Power sensor
How many Parrot Flower Power can I connect to my device?
You can control up to 256 Parrot Flower Power products with one account. You can (only) collect data or use live mode to one Parrot Flower Power at a time. The application will connect to each of your Flower Power devices automatically.
How long can data be stored in the Parrot Flower Power memory?
Normally data is uploaded by the application on a regular basis, depending on how often you are within range of your Flower Power. If the application has not been able to connect for an extended time (e.g. you are on vacation), data can be stored by Flower Power for up to 80 days without data loss.
Does the Parrot Flower Power work in the sand?
Yes.
What is the temperature range of a Parrot Flower Power?
From -10°C to +55°C (14°F to 131°F).
About the Parrot Flower Power application
Do I need to be next to my Parrot Flower Power to receive an alert?
No, you can receive an alert even when you are away from Parrot Flower Power. You can choose to receive these alerts only during certain periods of time in a day. To do so:
  1. Tap Settings.
  2. Move the Start / End cursors to set the time when you want the alerts to start / stop being sent.
How long do I have to wait before getting advice from my Parrot Flower Power?
After 30 minutes data starts to be displayed on the graph. After 24h the first advice is displayed on the plant menu in the application.
Can I connect several devices to my Parrot Flower Power at the same time?
Yes, if you use the same account. One device receives data which is synchronized on the Web Service. Then, this device sends data to the other devices logged in with the same account. Push notifications are sent to any device with the same account.
The application says I have to wait 24 hours to receive information about my plant, why?
The algorithms that monitor your plant require at least 24 hours of data to start providing advice. The more data-points the software has, the higher the fidelity of the advice that's given – so, ideally, you should plan on monitoring your plant for at least one month. The 24-hour waiting period is reset if the plant association to Flower Power has changed (e.g. Flower Power is moved), or if the Flower Power firmware has been updated.
Why does my Flower Power say fertilizer not available?
Fertilizer measurements are taken by Flower Power when the soil is wet, and fertilizer results should be available a few hours after a thorough watering, as long as your Flower Power has been installed in the soil at least 24 hours. If the fertilizer levels in your soil are very high and constantly wet, Flower Power cannot make an accurate measurement, and the application will show that the fertilizer measurement is not available. In this case, thoroughly flush your soil with water to remove the excess fertilizer and make sure the drainage is good, as it is likely damaging your plant at these high levels.

I'd like more details about the units of measurements used on the application
Air Temperature
  • Range: -5°C to +55°C (23°F to 131°F)
  • Accuracy: +/- 1.5°C (+/- 2.7)
The range of temperature that is generally comfortable for most plants is between 10-32°C (50-80°F). Various stresses may affect plants outside this range, but it is highly plant specific. 

Light
  • Range: 0.13 to 104 (mole x m-2 x d-1)
  • Accuracy: +/- 15%
The light sensor is calibrated to measure Photosynthetically Active Radiation (PAR), defined as light in the wavelength between 400 - 700nm (the visible spectrum). 

Soil Moisture
  • Range: 0 to 50 (%)
  • Accuracy: +/-3
The typical soil moisture range is between 8 (very dry) to 45 (saturated). The soil moisture will read 0 when in air. Generally, most plants require watering when the soil moisture is in the range of 12 to 18. If the soil moisture stays > 40 for too long, this may be harmful to some plants (overwatering promotes the growth of pathogens in the soil, and plants require oxygen at their roots for good health). Specific watering and overwatering thresholds depend on the plant type. Due to variations in soil composition, texture, compaction, and other factors, variation of the soil moisture readings can be greater in practice than the accuracy of the sensor suggests. To reduce these variations, always water around the sensor when it is first inserted into the soil to remove air gaps. When container gardening, always use a container with holes at the bottom for good drainage, and water your plant thoroughly, until a small amount of water emerges from these holes. 

Fertilizer
  • Range: 0 to 10 (mS/cm)
  • Accuracy: +/-20%
The typical range for fertilizer in horticultural applications is 0 to 4 mS/cm. Generally, fertilizer < 1 is low, fertilizer in the range of 1 - 3 is a good range, above 3 is high, and above 4 may to too high. Fertilizer usage and sensitivity is plant specific. After application of liquid fertilizer based on the manufacturer recommendation for your plant, you should immediately notice on the sensor that fertilizer is in a good range. When using compost or slow-release fertilizers, it can take a longer time for the fertilizer to register on the sensor. Due to uneven distribution of fertilizers in soils, variation on fertilizer readings can be greater in practice than the accuracy of the sensor suggests. To reduce these variations, always water your plant thoroughly -- this gives fertilizer the best chance to evenly distribute throughout the soil.
About my plants
What's the best way to water my plant?
When Flower Power indicates that it is time to water your plant, thoroughly saturate the soil with water. If your plant is in a pot, you should add water until it emerges from the hole(s) at the bottom of the pot. When you first install Flower Power into the soil, it is good practice to water your plant immediately, as this will remove any air pockets that were created when the device was inserted.
What's the best way to fertilize my plant?
When Flower Power indicates that it is time to fertilize your plant, follow the instructions provided by the fertilizer manufacturer. In most cases, indoor and outdoor plants require different amounts of fertilizer due to their rate-of-growth. Also, plants that are in pots usually require less fertilizer than those directly planted in soil. If you are using liquid fertilizer, thoroughly saturate the soil with the fertilizer and water mixture. If you are using solid (pellet) or other fertilizer products that are applied on the surface of the soil, water thoroughly after application.
What can I do if my plant gets too hot or too cold ?
An outdoor plant that is too hot can be moved to a location where there are many other plants, or next to ponds or pools. Stay away from walls, driveways, big rocks, or other objects that absorb heat during the day. However, if your outdoor plant is too cold, move it closer to these kinds of features. Make sure indoor plants that get too hot are located away from heating radiators and vents.
What if I can't respond to my plant's needs?
In most circumstances, you will have several days to react to plant care advice. If you know you’ll be away for a few days, you can consult the agenda to determine what actions will be coming up soon. If the action is colored orange you have several days to react, if it’s colored red, you must address it quickly.
