You can just build one with one operational and some parallel mosfets on a radiator and attach a esphome If you want wifi. You have q challenge to set the esp to control the load, but it's not complicated.
If design maters for you buy that one.
I have lot of equipment in my work lab, scpi sw control made by me in Python including gui, zero are wifi-linked.why wifi? If your DUT îs smoking you're gonna stop it with wifi?
