Did the HoneyPi Beehive Libra. (https://www.honey-pi.de/).
Housing in the pictures was glued with hot glue ... I edited it to screw it to the sheet metal.
Ordered a few things other than on the description of the homepage.
So my setup is a Pi Zero W, a HX711, a BME280 and the following things...
Took a libra for packets. Load cell is to wire like the one from banggood described on the honey pi homepage. (https://tinyurl.com/u2v6mf4)
The solarcell and pwm is this: https://amzn.to/30yrm5p
Batterie I was using this: https://amzn.to/3apu5Cr mentioned it is too small. Will use this instead: https://amzn.to/2vr1aOF
Then just 12 screws (M3) + 4 Screws for the housing of the Pi and a piec of sheetmetal.
Print the housing, the cover and the battery holder. You can choose the housing whether you use WiFi or mobile network.
Amazonlinks are ref-links, so the devoloper of the hivescale profits a little bit of it ;)
Update: Added parts for the solar cell to give it a stand. To Install it you need a 13mm rod. Length depends on the angle you want to have.
