Amazon was having a sale on Ecowitt weather stations. I had my eyes on them for a while so I finally bought one.
Setup through the WSView Plus app was painless. It has a local-only option and Home Assistant picked it up without drama too.
The sensor array is a WS69. It measures temperature, humidity, wind, rain, light, and UV.
For mounting, I used a length of 25mm conduit I had on hand and bolted it to the greenhouse frame. The manual has instructions about distances from buildings and height, but this is the best I could do. It is above the roofline and reasonably clear.
