willing to optimize my MySensor Network at home and this would be my actual need:
The Gateway:
temporary Pi2 over the network
cover with 4 ds18b20 the central heating system pipes (2 zones)
Already done with a nano device
rain sensor
already done with a nano device
cover my garage (from balcony at around 30mt in vertical view) in witch I would like to monitor:
- Car presence (with a ultrasonic ping)
- Lights (2 indipendent lights with a relais)
- door position (open/close) with a reed
My intention was to optimaze this all in this way:
- leave the 1wire temp for heating where it is
- remove the PI2 gateway
- Use a nodeMCU installed on the balcony to act as MySensorGateway (WiFi via ESP8266), adding rain and external temp sensor capability
- Use a nano installed in the garage for lights, ultrasonic and door sensor
all radios wil be upgraded to NRF24L01 PA LNA to gain signal

but I have few question for the new gateway....
can I add sensors to a gateway? I've seen that could be done...
does old sensors needs to be reprogrammed to get the new node_ID from the gateway? or just a reboot will let them appear on the new gtw?
...may I share here to get your opinion my tentative to join the gateway and rain/temp sensors in one device?
ciao
