+### So what's still missing
+- Tasmota wall power, doable
+- Average CPU freq, doable
+- Per-core CPU load, doable but annoying
+- FPS counter, maybe possible?
+- Active core count, probably impossible but loadAvg is better?
+- GPU board power, probably impossible, it was estimated on windows anyway
+- CPU cache/iod, likely impossible, zenpower doesnt show it
+- GPU clock limit, probably impossible, amdgpu doesnt show it?
+- CPU fan, likely impossible, no modules
