TED $20 Ebay

The company used to do some kind of magic on the unit to open it up, and allow it to run their marginal software.

Now they've abandoned the 1001 and moved on to products with a higher profit margin, and are dumping the old units, which ended up on ebay.

It's a lot of useful hardware for $20, and the as-is functionality is also easily worth $20.

However, back on THIS POST I posted some links to activities that are already successful at gaining the access you are seeking to this device.

I'm kind of hoping that NiHaoMike will do an appropriate hack on the unit and show us a complete and simple way to get the useful data out. It's not completely outside the realm of possibility...

There are already some successful hacks out there, but none of them that I looked at seemed really straightforward.

BTW, I think this thing is so useful, even without a glorious hack, that I bought a second one for monitoring my heat pump.

There's also available just the monitoring part (no measuring parts) being sold for cheaper, so if one is going to attempt a hack that involves the readout head, you still have a working readout in the interim.

Lastly, I encountered a small problem involving the two phase branches of the 220VAC...

Seems that if you connect the sensing unit to one particular phase branch, and your monitoring head is pluged into the same phase branch, no problem. However, if you plug your monitoring head into another phase branch, there is no data. So it is important to have both the sensing unit and the monitoring head on the same phase branch. But there is a fix to allow data monitoring from either phase branch, and that is to employ a phase bridge. Leviton makes one that can be found HERE.

The other approach involves a 0.1mfd 400V non-polarized cap connected from one phase to the other phase. Doing this in the electrical box would be dangerous, but constructing one into a 220 VAC plug, and plugging that into a 220 VAC outlet could be a solution.


HERE IS another DIY phase bridge that uses more parts and also has a formula.

I bought one of the $20 TEDs. Is there a way to use it to measure just my ASHP water heater or ductless split? Or does it just monitor the whole house?

[Xringer]

It will monitor which ever lines you snap the current probe onto..
I used mine to measure my Mini-Split for years.

Now, I have the clamps over both the 230 lines to the Sanyos.
I read their combined power use (if both are on).

[Xringer]

Since I have two Sanyos, I'm thinking of adding a second TED (from Ebay $20)
so I can see the power being used by each unit.. (make it easier to notice problems).
Right now, I see both Sanyos on one TED display..

The old TED I got years ago is working great now..

So, I'm wondering if I could install both units on the same filter setup?
And not get a lot of data packet collisions ??

Anyone know the duration of TED signals?

I posted some 'hack' links previously.

Look there.

The duration isn't to hard to figure, since it seems to be a 1200 baud signal.
I think the timing of the packets, might be a problem.
But, since this older model may not have USB routines active,
the start time of the 11-word data packets may not be in sync.

If they are in *sync and the collision rate is high, work-arounds can be tried.
(*start transmit might be triggered by a 120vac 60hz zero-crossing detector).

I'm going to place my Ebay order and keep my fingers crossed..

You really should check the links... this stuff has already been done.

I read a lot of the info and stuff from other sites, but I haven't seen
anyone write about the start timing of the data packet.

I'm trying to anticipate the interference problems with connecting
two transmitters to the same AC breaker circuit.
If the TED controller gets timing from the 60hz of the grid,
there could be data packet collisions. Lots of them.

The new TED will be here in a few days, so I'll sort out any problems soon, if there are any.

One of the links was to the site maintained by a geek girl, with a powerful bench of tools which she knew how to use very well.

She completely designed a TED receiver from scratch, in order to sidestep the non-working USB.

Needless to say, her first step was to completely define the characteristics of the signal before she started designing hardware and firmware for the micro-processor.

I have a TED 5000-G that measures house power and solar power.
I would like to be able to measure the new mini split but an extra MTU and clamps is $90.
I called TED tech support and asked if I can hook up a 1001 and TED 5000.
He said just power the MTU on different legs and I should be fine.
So I just ordered the TED 1001 off eBay how can you go wrong for $20 shipped
