How to prevent a GeyserWise losing its settings 

Yes, still working fine. I since found out that there is a button-type battery in the Geyserwise display unit that needs to be changed when it looses time & settings, but keep forgetting to check. The battery is still useful to keep the display going.

@@SterremanWillie Post that video when u get a chance pls

​@@SterremanWillie hi Wiilie, my display skerm verloor ook tyd met LoadShedding. Ek het al die battery 2 keer vervang, maar verloor nogsteeds tyd. Enige raad?

I also measured 16V which worried me as well, but its been running since I made the video without any problems. The battery does not heat up either, so seems to be OK.

Thanks Willie@@SterremanWillie

I suspect it is not recommend because lithium technology use different voltages and currents to charge, compared to the Geyserwise charger which is designed for a lead-acid battery. It could result in the charging circuit of the Geyserwise to fail. Lead-acid batteries are far cheaper anyway and you don't need a big battery either - my 7Ah is an overkill already.

Its difficult to faultfind like this, it could be a number of reasons. I once had to change my Geyserwise when the output port for the 12V motor blew. The 220V port still worked. This I determined using a multimeter. I don't quite follow what happened, sounds like the motor did not work after the uniit was replaced?

Hope you solved it but just to check 1. Is the probe on the collector working fine? 2. Double check the terminal connection for the pump. My geyser was worked on and the terminals were loose. Resulted in intermittent pump working and saw temps of 80 degrees. Since I retightened them, all works fine

Sjoe! I'm not an expert on Geyserwise, and have not experienced this problem yet, sorry. I assume you tried to Google?

I have. Thanks though. I just bought it so perhaps will send it back to supplier.

@@mhb3088 good idea. Hope you get sorted.

Other major problem with Geyserwise is if it comes on after being powerless and its in the middle of a heating cycle, It does not re-initiate the heating cycle. Surely based on time its obvious, it should just restart the cycle.. Junior programmer I think!
