Smart heating with Drayton Wiser
We recently installed a Drayton Wiser smart heating system, which looks like it’s going to work well in allowing me to just turn on one radiator in the room where I work from home. These two videos from Charlie DIYte were very helpful:
When we got into the fitting, we found that some of the radiators (fitted 12 years earlier) needed adapters from 28mm to 30mm, and we purchased these from Low Energy Supermarket
Although the smart TRVs themselves were able to form a Zigbee mesh without too much trouble, working with the system became easier when I got a second node for our WiFi mesh system. I like ASUS WiFi routers, and this RT-AX57, although feeling a bit plasticky, solved the problems. As a side note, if you want to go deep on ASUS routers, this article has lots of depth.
I found that I didn’t understand the numbers on the packet, and what AX1800 or AX3000 meant. This superuser.com answer had it:
The numbers indicate the cumulative maximum theoretical bandwidth for all the devices in the package.
The Bands Available and their maximum theoretical bandwidths are:
- 2.4 Ghz: 480 Mbps
- 5 Ghz: 1300 Mbps
For a single device
- AX3000: 2.4 + 5 + 5: 480+1300+1300 ~ 3000 Mbps
