I am looking to add a temperature sensors in every room of my house, plus some external sensors outdoors and in the roof space.
Indoor sensors is there really much difference between all the brands? i current have few SONOFF SNZB-02D and Ikea VINDSTYRKA, however i am wanting to move to no display, zigbee + battery powered. so looking to just get SONOFF SNZB-02P however before i pull the pin i just want to make sure i am not missing anything in terms on accuracy and quality on the sensors?
For roof space, i am thinking best options will be esp32 with POE + I/O Multiplexers + BME280 (or similar); the conditions in the roof space is very dusty so i might need to look at the impact that has on the chosen temp sensor.
For external i really haven’t found much that is reasonable price and IP65+ rated, any recommendation? or am i better of going down the esp32 route as well.
I have a SNZB-02P currently installed to monitor my bedroom temp and humidly levels and its been on the same battery its come with almost a full year now with it still showing 100%.
From what I can see in the logs it fires off a check in event every 1hr.
Its been pretty accurate thus far vs my airgradient one that I use in the center of the home and the switchbot hub2 I use in the bathroom.
As for crawlspace and POE capable you could look into say this one:
and just use an adapter like this to power it via POE to USB:
That Apollo also has the option of using a long cabled probe so you can keep the main device indoors and just stick the sensor probe outdoors.
