IoTaWatt is very popular down-under because of it’s robust three-phase capabilities and ability to upload to PVoutput. But there are challenges to making it economically viable. The voltage transformers are heavy and expensive with a unique plug type. Shipping from China to the USA and back down to Australia is not only expensive, it leaves a huge carbon footprint. This problem exists in other areas as well where the local plug standard is different as in the UK.
Fortunately, there are local sources for these and a few early users provided samples that were calibrated and added to the tables. You can order these items locally and use them with the same confidence as the Euro plug VT sold here. While you’re at it, you should order a native plug micro-usb power supply. Note, please report any broken links.
UPDATE: Radio Parts has apparently changed supplier for their 9VAC transformer. While the replacement is probably suitable, we would need a sample to measure calibration and phase-shift in order to recommend and add to the IoTaWatt supported device table.
Basic bundle includes:
- IoTaWatt Base
- additional 100A CTs (split-core)
- additional 50A CTs (split core)
- additional 50A CTs (solid-core)
- The basic bundle weighs less than 2 lbs and ships for flat-rate $15. If optional components increase the weight beyond 2 lbs, shipping increases to $25 flat-rate up to 4 lbs. USPS shipping is available for heavier packages or for faster service. See shipping.
