@GertSanders Thanks, It would be used for remote temp. sensing in a Ref/freezer/aquarium.. etc.

Is it possible to add an ds18b20 to the Sensebender?

The battery life on the SB is VERY good.

Late to the party...., but I absolutely love Fluke. I have several and they are build very well.

@petewill Seems to be working this morning.. :scream:

I get away with a lot of stuff, but there is no way my wife would let me do this.. :-) Why did you turn off the YT comments?

Looks Good!

Here is an interesting article http://www.vptpower.com/wp-content/uploads/downloads/2012/01/info_inrushCurrent.pdf on the subject. Looks like there is a LOT more to it (not that I thought there wasn't) than my over simplified post above.

@m26872 I'm no expert either. :smiley: We may be saying the same thing however... I don't think it matters (AC or DC), if there is a transformer in the circuit, there is going to be a current peak on startup. If you have a filter cap before your transformer, you will see 2 peaks. The first one will be caused by the capacitor charging up, and the second from the inductive load caused by the transformer powering up. I'm thinking the 2nd peak should be much less due to the filter cap.

Of course I could be all wrong. :persevere:

This in-rush 'effect' can be seen on any induction load.

@blacey How is the project progressing? I can't wait to get my hands on this. (even though HomeSeer may not be able to incorporate it yet ;-) )

This is very nice!

@korttoma Thanks for the heads up on Unionup.

@korttoma Say what...? You measure .4 ohms on your Varistor? I think you found your problem. :angry:

I have only ever used Varistor protection on the primary side, so I've got no experience with low voltage Varistors, but I don't think it should ever read .4.. Should be infinite.

@hek whats up with that NORDIC board?

I think a vibration sensor may work better in this case, and there are examples.

@tbowmo Oh now that is sexy.. From someone with back problems, you take it easy for the next 3 days Sir!! :point_left:

:stuck_out_tongue:

@tbowmo Sounds Good, Thanks for the update.

@tbowmo How is the testing going?
