I used the setup in this post
“Wiring a solid state relay - #5 by AlanDavis”
you most likley could add more Solid State Relay’s (SSR) I used this SSR: https://www.amazon.com/gp/product/B01MCWO35P/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 I also added a light switch to cut all power to the router for safety reasons.
