  1. Been using Openhab now for almost four years . Here is a LINK of the setup I posted on another page. Personally I tested both and the reason why I went OH is that they have a Proxy server that works out of the box. You install the plugin register the on the site and add your UUI and Secured code. No need to port forward and it is for free. But apart from that I could not see much difference for what I an using. Also after three years you tend to know the interface so it is "easier" to setup
  2. @Stef that is a cheap android tablet that I used.
  3. It is looking good well done! Here is some additional points to consider. Ensure that the geyser will not switch on while you are on battery power unless it is not a problem and you battery bank can handle it. One way of handling it is to ensure that the contact is powered from the grid feed. Should the grid fail the contact can not close. Have some way of monitoring your battery watts should the draw be lower than ,for example , -2000 w let it switch of the geyser. Have a hard timer in the loop so that the geyser can only be switch automatically during day time unless you
  4. Getting back to the Original question If I do the same "Straight-line" comparison I use about 12 kwh of alternative energy (Solar + Batts) so this will give me R 63 saving per day. Keep in mind I live on a farm with prepaid but no line rental so the price per unit is very high but I only pay for what I use from the grid.
  5. Ok , so this project has been ongoing for the last three of four years and in fact is still going on we have learned a lot on hydro power and possible pitfalls. but I wont bore you all with the details. Here is what the "final" product looks like. Ps. Not my system , hope to have one going in a year or so - (Need to raise the capital )
  6. Still a work in progress. But I have build a dash to display all the different alternative energies on one page.
  7. One more idea , should any one look at this. Most alarms have an audio output , 12v , to drive siren. So 1) Dead simple method - 12v - 220v contact to the lights. They will then come one if the siren is activated and switch off if the siren is off. 2) 12v interval timer. - If triggered run for 10,20, 30 min and then reset. Wire the light in parallel with the relay so that you still have control to manually switch in the lights. There is a ton of other ways to do it but this is , in my mind , the dead simple method if you want to drive it from an existing alarm system.
  8. Looking good. Well done. You should also notice that when you start to run hot water the temp will spike as the hottest water will be on top. As the old saying goes " he who measures will know" ...
  9. @JJS - What is the full speck of your system and how do you monitor your data the values does not seem correct on average you should see conversion losses of about 15% - 20% .
  10. Here is a thought , span the begees out of those contact numbers. Keep the crook busy so he does not have time to scam ignorant/desperate people.
  11. Sure it is quite simple. So i have a SonOff running Tasmota on it . You will need to flash the sonoff with the new firmware. This will add the benefit that you can add atleast 3 sensors to the SonOff , (TX , RX and GPOI14 , I think thats the last pin). In tasmota to you just select the correct sensor for the pin that you connected that DS18B20 sensor. Here is a tutorial as to how to wireup the sensor. The nice part of tasmota is that every thing is already done and you only need to add the broker details and it will publish to sensor data to the "tele/#/SENSOR" topic. Here is some pict
  12. A buddy of mine used a old Android connected to the mains. There is an app that will send you a SMS , guess maybe another trigger if the phone stops charging / grid fail. Simple but very effective. If you want to go one step further you could use something like Tasker (Android) - then you can have all sorts of stuff setup when the grid fails.
  13. True but these are mostly aimed at commercial applications and the rates will me more or less the same. The only difference is that the "hardware' are , in some cases , considered as collateral..
  14. I guess the easiest way to look at is As per usual do you want to save cost or stick it to the man.... If it is the latter - go for it as there is no argument for principle decisions. On the other hand .. In CPT it looks like average cost is about R2.50 per unit if you are going to use less than 1000 units per month - just got the value of a quick google search .. Lets assume that most people can get Prime + 2% , although some of my clients recently go as low as Prime -2 - rather stick to the upper part cause if that one work it will definitely work the other way .

  15. Hello @Abdul Gool I had a slightly closer look at the info in your calculator. I assume that I am missing something so Ill ask In your data collection you ask for the Loan amount , term and rate. Then you introduce a solar-kit/quote into the mix. Is that for reference ? I t seems like it is added on top of the installation amount and will have an effect on the calculations. If the design will be grid tie only and not a hybrid system , keep in mind that the bulk of the users end up here as a result of load shed an the savings part is a "bonus" ( This is just my point of vie
