hi, I have the chinese 1.5kw vfd and I a couple of questions about the hy_vfd component:
1) what's the use of the vfd.spindle-speed-fb pin? I see that it's a calculated value as opposed to the vfd.RoTT pin which seems like actual feedback from the vfd. both seem to be outputting the same value.
2) has anyone gotten the vfd.Tmp pin working? I see in the comment that it's use as temperature is "to be confirmed". I'm getting a 0 value reading and was wondering if it's something wrong on my end or if the vfd is just not reporting that value.
