Absolutely. Cheap hardware means corners cut... regardless of how open the software is.
Shelly devices are quite open and well made but easily 2x the cost of other wifi relay devices. Belkin WeMo devices are similar price to shelly and about as well made but their software leaves literally everything to be desired.
