It couldn't stay at L1 for longer than a few months.

The accelerometers would be sensitive enough. Those on Mars Insight are rated down to 10-9 ms-2 Hz-½, for instance.

But the electrochromic material's degradation due to ultraviolet radiation would limit how long the panels would operate. On Earth, outdoors, at sea level, they would last at most "a few years." Earth's atmosphere blocks 77% of UV, so the UV just outside Earth's atmosphere is 4.3 times stronger. Venus is about 0.7 AU from the sun, so the UV is twice as strong there. So the panels would last "an eighth of a few years," just a few months. Mechanical devices would last much longer.
