My sensors for Temperature, Humidity, Motion, Light level, and Door sensors were all working well, however, my dimmers, relays and switches were intermittent at best.
I tried all the suggestions here and had no improvement.
I monitored one of my node that had a relay and did see any on or off commands coming to the relay.
PROBLEM SOLVED
I thought the NRF24L01 on the ethernet gateway might not be transmitting reliably, so i changed it out.
Every switch, dimmer and relay work perfectly !
