The sensor knows
What Plant Mate watches for on your monstera.
Each target is sourced from horticultural guidance, quoted in full so you can see exactly where the numbers come from.
Ambient temperature
20–30 °C (68–86 °F)
“It prefers bright indirect light and temperatures of 20–30 °C (68–86 °F).”
Light
Bright indirect — no direct sun
“It needs very bright exposure, but not full sun.”
Watering cadence
When the top of the soil dries — about every 1–2 weeks
“It is usually watered when the soil has slightly dried out (after around one or two weeks).”
Soil
Well-draining, peat-based, with perlite and bark
“It requires a well-draining, peat-based soil to thrive, such as a soil made with perlite and pieces of bark.”
Plant Mate, translated
What each face means for monstera.
The mascot on the e-ink screen reflects what the sensor sees. Here’s when each expression shows up, and why.
happy
Inside the targets — warm, bright indirect light, soil moist.
“It prefers bright indirect light and temperatures of 20–30 °C (68–86 °F).”
thirsty
Soil's been dry past the 1–2 week mark.
“It is usually watered when the soil has slightly dried out (after around one or two weeks).”
cold
Ambient dropped below the safe minimum.
“Growth ceases below 10 °C (50 °F) and it is killed by frost. A steady minimum temperature of at least 13–15 °C (55–59 °F) is preferable.”
sunburnt
Direct sun detected at the leaves.
“It needs very bright exposure, but not full sun.”
