Hi AAC-Community!
I'm excited to talk to you about my new little project. It's sound simple but I think it is a good starting point. I'm working on a IoT-Station to measure temperature and humidity with wireless sensors and display the data on the smartphone.
Following you will find the specific requirements that I am looking for.
Sensor:
I already evaluated two possible RF-Modules. Please find below my pros and cons:
ESP8266:
+ no gateway necessary, direct connection to Blynk
- high power consumption but probably not possible to run stand-alone
NRF24L01:
+ low power consumption (made for coin-cell and long term applications)
- Gateway necessary to send data to smartphone
So far I liked the version with the ESP8266 chip because of the direct connection to Blynk (no gateway) but due to the power consumption I don't think it is possible to run them stand-alone in small size over months. Although I saw some workarounds with the ESP8266.
Therefore I think I go with the NRF24L01 module and an Arduino. I thought about using a Raspberry Pi to collect the data and send them to Blynk.
So these are actually my current thoughts and below also some questions I'm working on it at the moment. I'm excited to hear your feedback.
Would it be possible to setup an ESP8266 for my requirements concerning power consumption?
Does anybody has some experience with Blynk? Any advice?
And would it make sense to use a Raspberry Pi as a gateway with the idea to store the data history locally and send them to blynk.
Thank you for reading. Any kind of comments are welcome!
cheers

Following you will find the specific requirements that I am looking for.
Sensor:
- Measurement sensor + RF-Transmitter + uC
- BME280
- Stand-Alone operation over months (Coin-Cell)
- Send 1 data package per hour
- Small size (miniature sensor, as small as possible)
- range <10m (indoor)
- show measurement data on a smartphone (history graphs, notifications etc.)
- use a gateway to collect data and send them to an IoT-Service
- Gateway: Raspberry Pi (preferred) or Arduino
- IoT-Service: Blynk
- multiple sensors
