This was never intended for commercial use

At eQ-3/ELV, we developed equipment for smart homes, e.g. to control light and heating. The products were designed for home use with respect to pricing, quality, and features.
Earlier this year I visited an engineering company in the Lake Constance region. Engineers had been assigned to provisional laboratories until more office space would become available on premise. The provisional use had regularly been extended for several half-years in a row without the prospect of change in the near future.
I was surprised to see ELV power management devices connected to electric heaters. All offices on the floor had been equipped with the devices. It appears that also large enterprises seek cost reduction potentials by replacing commercial-grade building management devices with devices intended to be used in private homes.
