ESI Centro heating hub

KimmyH — Fri, 23 Jan 2026 13:21:33 GMT

My ESI Centro WiFi hub which allows me to control my heating via the app is not compatible with the full fibre broadband 5KHz that was installed yesterday, because it is on the 2.4KHz band. I contacted them & they tell me I can broadcast both bands at the same time from my router but do not tell me how, has anyone got any tips. The router is a SR203 model - help!!

@KimmyH From the Tips above on the community page, but the link is below for you, best to do it Ethernet connected if you can!

Split Sky WiFi bands

@KimmyH admin is your username, the password is on the label back off the hub, or the card you got with it!

@KimmyH Rather than reinvent the wheel, just change the 2.4Ghz band name ie SKY?????24G by adding the 24G to the name, dont be putting in a point ie full stop, NOT an allowed character..... When done, save or apply the change, switch the hub off for a minute back on and after you get all the Green lights again when you check you wiil see the two names to choose from!!!
