Most Cost Effective System Upgrade Options
Having initially bought the Smart Radiator Stat 3B+ Starter Kit for appraisal, now trying to work out the most cost effective options to expand the system without device duplication should I decide to proceed.
I assume that the "Extension Kit" is now obsolete and I would need to add a "Wireless Receiver" to implement boiler/MOV control, replace existing programmer?
The wired or wireless thermostat kits both include an internet bridge which I already have, am I correct in assuming that the "Add on Wireless Temperature Sensor" is the same device as per the kits and as such buying this/these as required would avoid duplicating the internet bridge?
Obviously additional radiator stat's will have to be added as required, what's the most cost effective way to buy these?
