Hi All,
I live in a small home which is 1600SQFT and it consist of 6 rooms in 2 levels.
How many sensors required?
Should I need to have 1 at every level so, it will be 2 or I need to have 1 at every room.
Depends on the architecture and composition of the house, but generally 1 at each level if centrally located is sufficient. If a wing has a large variance from the central then it may need an additional sensor.
A lot of sensors whose primary function is something else (motion, for instance) also report temperature, so with the creative selection of sensors you can basically get temperature as a side benefit.
It depends.
I have four door separated rooms and five in total (kitchen attached to lounge). I use 2 sites for sensors because I have two different temperature zones. Priscas room, and everywhere else and everywhere else is effectively open plan because I live alone, and because a temperature drop in a single room could have me in hospital.
It also depends on the heating system/hvac involved. Central heating with controllable radiators, you can sensor every room and use that to provide heat to rooms you are using at times you are using them and vice versa but while people can give you advice they aren't your user case..
If you have electric heaters the first method might work better. Central heating the second would be more efficient but efficient enough to pay sensors in every room, they aren't always cheap?
I might look at how much I use rooms on a daily basis and how often doors are left open between rooms (effectively open planning them) and then choose sensor points accordingly - putting any sensors around shoulder height because you would be surprised the gradation of temperature difference between mounting a sensor low/medium/high in the same room..
A happy sleeping temperature for most people is around 18c or so apparently.
But ymwv.
PS Invest in a temperature gun if you don't already have one, they're cheap on amazon etc, but they are properly calibrated. A lot of the sensors aren't. I have three sensors within 6 inches of each other (WiFi Tuya, Hubitat Zigbee Tuya, Broadlink RM4PRO (reporting to Hubitat)) and they're all different - the temperature gun is a different value again, if only slightly..
I live in southern part of India and temperature here varies from 18 degree to 40 degree.
And the place I live will have more humidity. So I need humidity sensor as well to automate the fans and AC as well.
So I went with these

As this brand is much reliable among the device I own. And planning to use them on two level as I have only two levels.
Keep your comments coming as it will help others to decide who lives in other regions.
