@mfalkvidd Ok a day after posting this I just dismantled everything used a new batch of Arduino Nano's and NRF24L01 with a breakout connector Link to Amazon and everything just came up without an issue. Lesson learnt even if you try different components don't rule out double and triple hardware failure points. Once I had a circuit working I went through every Arduino Nano and NRF24L01 I own, I ended up with 2 Nano's that refused to work and a handful of the NRF24L01 as well. Anyway things are now working with the serial gateway (next step is to try an MQTT one again which is where I started this whole project from) and get an irrigation controller running.
