Your best bet for measuring all types of precipitation reliably are with a present weather sensor, be it from OTT Hygromet or Optical Scientific. The "only" caveat to these are that they run around ~$5000 to $10,000. I don't believe these directly do snow water equivalent readings but you can easily calculate that.
You probably won't find this technology in home weather stations for a long time if ever.

The Parsivel
2 from OTT uses a laser to discriminate droplet type and size. Optical Scientific manufactures specific sensors for precipitation measurement for rain and snow. Those use IR scintillation to derive type and intensity/accumulation. Both would require a dedicated logging system and communications equipment. $$$
Otherwise alternatively weighing gauges are a cheaper alternative though still in the $1000s. Putting up the appropriate wind alter shields around one of them and filling the gauge with anti-freeze allow for winter snow-water equivalency measurements is a valid approach. That's what the NYS Mesonet does. Or heated rain gauges in the same setup though still having to compensate for evaporation. Those also typically require mains power.
There's really no cheap way to do it if done properly.

Either not at all or requiring $$$$$.
Even with automated snowfall measurements many mesonets are adopting using sonic depth sensors, there are nuances there as well. These don't compensate for drifts or if the ground melts the snow during slow accumulation. Present weather sensors are really really good at what they do but at a prohibitive price point.
Siting for anemometers is the biggest factor for "accurate" measurements. That goes for any anemometer. Picking up a $3500 3D sonic from R. M. Young and putting it tens of feet behind a two story house will perform worse than the Acurite 5 in 1 sited 10 ft AGL in an open field on a farm. Really comes down to context.
