What a piece of crap. What good is great service if all they do is keep shipping the same defective product day in and day out. Two weeks in on a replacement and the the first brownout reset to 400watts again. what programming whiz designed this crap, Gavita?

Find a tec to program one of these for reliability

Frank has it right, a PLC can do the exact same thing, the controller uses pulses of DC voltage from 0 to 10VDC to control dimming and power off/on and the heat probe is just an analog sensor. A tech can build and program but it may cost more than an EL1 or EL2.

I found it easier to just plug the EL1 brain into a small UPS (battery backup) along with the wifi repeater and any other mission-critical timers

Shouldn't have to use a UPS, if Gavita could get the factory to use a decent battery, then no issues, just like Honeywell purchased AUBE, and fucked up a very reliable digital timer.

Same could be done much cheaper, with a raspberry pi and modules, by using the superb opensource project mycodo

Back to the EL1/EL2 looks like the battery drains on itself... looks like a flaw in the design or assembly.
