Mclean Electrical have been installing honeywell zoning systems for over 4 years, we have installed over 100 evohome systems and all of the systems work fine.
Signal strength issues are usually due to poor installation design, and not having the experience to position the devices correctly. The evohome system is reliable and solid if installed correctly. We have successfully installed systems in very large properties, manor houses some with walls over 1m thick.
Evohome is a powerful adaptable system with many options available, there is always a way to make a system work reliably.
