@mfalkvidd you're right, there's a lot of 2.4ghz pollution from every device these days, no avoiding that, but specifically having 2 transmitters so close to each other has never been a pleasant experience for me.
I don't think I've read anything about serial gateway not working on esp8266, it's more the lack of any mention of it anywhere. I mean logically there's no reason why it wouldn't be prevalent, as esp8266 like the D1 Mini costs the same as a nano, is faster with more memory, uses micro usb, no real downside.
Plus, if you free up the wireless module, you can even use the esp-now protocol instead of connecting a nrf24 (which unfortunately hasn't been implemented in mysensors yet)
