• That sounds good - so how will you get that data online? The ESP32 will just POST it to drazzy.com, or drazzy.com will request it direct from your home IP address?

    I know you like the 433Mhz stuff but you could take a look at nRF52... The modules are small, cheap, and have radio on them. Also the ESP32 can now grab the BLE advertising data, so with a few of them as receivers you could get good range.

    Have you seen these guys too? https://www.silabs.com/products/wireless/multiprotocol-connectivity - there's a port of Espruino to the EFM32 so it should be pretty easy to get it on those chips - and they have all the radio stuff for 433MHz on-chip!
