Hi, I would definitely use the POWR3 25Amp on a geyser. Its quiet large and does not fit in the DB board but can definitely handle the load and has screw terminals. The new POWR320D or POW Elite 20Amp should also work. We are busy testing them now in South Africa condition but it will also take some time to get them certified. It will definitely be alot more cost effective. The Sonoff TH Elite 20Amp will also be a good option.

Hi, Sonoff SPM and SPM4RELAY can be installed in DB they have 4 x 20  amp channels that can monitor power. Ewelink app which is the default Sonoff app now has a power dashboard so you can track usage. Its not as simple as a clamp type solution but it gives you the ability to switch of loads during loadsheading. Generally you need a additional board because they are big device's. They work well and have overload protection. If you dont need the ability to switch off loads the clamp type solution is much easier for monitoring only.

Hi, How are you? we have Sonoff and Broadlink that we import directly. If you want to switch aircons off durring load shedding at night it can be done by using the Loadsedder and a broad link. Via IFTTT.  Also if you allready have a POW that IFTTT can probe it can also do it with a ampplet from IFTTT just ust the one thay says if my power drops below x then switch of Broadlink aircon  
Hope that helps.
