OWL and RFXtrx433XL USB HA alternative

I have a need to monitor three power consumption values within a single consumer unit.
I've used Owl devices in the past and my first thought was to use these but I don't have an RFXtrx433XL USB HA and they appear to be unavailable everywhere.
Ideally I'd like a solution that uses clamp sensors that split to allow them to attached without breaking the seals on anything.

My plan is to have a Pi running Domoticz located by or somewhere close to the consumer unit to act as a data source for my primary Domoticz server which is virtualised and has no physical ports.

I've spotted the pzem-004t option but this appears to be a closed ring and would need a PSU and enclosure, i.e. finishing off.

If people could let me know what they have used and if they think it's still available I'd be very grateful.

Kind regards
Charles

A good solution, without a doubt, is to have an RFXtrx433E USB 433.92MHz Transceiver card, and use the EX equipment. OWL CM 180 with clamp sensors.
Works perfect! But I only have one clamp.
It may not be easy to arrange the equipment at the moment but,try to find the sale, in my opinion with clamp sensors, OWL was a good solution!

Agree but from the manufacturers website "RFXtrx433XL not available. Unknown if or when a new product becomes available."
I can't find any for sale anywhere so I've messages the manufacturer.

If anyone has alternate suggestions or for a replacement for the RFXtrx433XL I would be very grateful.

What about RFLINK?
I don't have any experience with it but OWL support is documented.

I am also looking at this right now and an alternative may be the Aeotec Smart Energy meter (Same principle - can connect up to 3 clamps) - I have just posted a question on whether anybody has experience with this.

I currently have an RFXCOM but it's apparent discontinuation is making me nervous - If mine files I will have around 100 devices which won't be able to communicate to Domoticz.
