IoTaWatt clearances for recessed installation

My main electric service panel is in a finished basement room, recessed between the wall studs, with drywall around it. I’ve been trying to figure out an appropriate recessed enclosure to mount two IoTaWatts inside. I just received the IoTaWatts today and I measured the bare minimum clearances to fit the two stacked one on top of the other, with rubber feet and all cables attached:

54mm x 153mm x 159mm
(2.13" x 6.00" x 6.25")

This doesn’t include the AC transformers or USB power adapters, and another challenge I have is the space near the panel is limited. There is a bit of space below the panel (368mm / 14.5" wide, 200mm / 8" high), but not much to the left (280mm / 11") or right (190mm / 7.5"). Additionally, there is a piece of flex conduit coming into the bottom of the panel so that reduces the available space to maybe 165mm / 6.5" wide below the panel.

Has anyone successfully used right-angle 3.5mm adapters on the CTs to reduce this further? Has anyone else mounted an IoTaWatt or two inside a recessed box?


Bob Lemaire the developer of the IotaWatt now has his own forum here
It may be more appropriate to ask the support question there, as he should know the heat dissipation from the units, etc.
