I have 7 Sonoff devices doing all sorts of work.

I need a system to control a 3kW geyser including a temperature probe.

Please advise on what is required and how to do it.

I plan to replace a Geyserwise with it.

Did you see that Geyserwise have an IoT module / addon that you can now get?

Nothing on their website.

I’m also interested in an add-on. Agreed with Johan don’t see anything on the Geyserwise website.

Hi @Johandup

I control my geyser with a red pole wifi switch that can be bought from Takealot, works like a bomb:

https://www.takealot.com/red-pole-energy-geyser-smart-wi-fi-switch-energy-monitor/PLID91347311?gclid=Cj0KCQjw48OaBhDWARIsAMd966DlKWq87z8_4O7dEOg49c4MU5uesKg2i6G8TgYPxc9eb1wJncpb9fUaAgenEALw_wcB&gclsrc=aw.ds

It does not have a temp probe, but i suspect you could just add another sonoff at your geyser that will measure the temp and make them talk to each other by creating an automation or a scene?

here is the sonoff: https://sonoff.tech/product/diy-smart-switch/th10-th16/ You should just be able to make a small housing on the geyser tank and pratley stick it on.

Its crude, but should work. i think i will be trying this soon enough. 😄

Hi @Brian_SA

I will never buy a switch which has 63a on the front but says in the print not to exceed 5000w. 
The only issue with Geyserwise is that it is not possible to manage it via the internet. 
Its ability to stop start at 4 different times per day at set temperatures is very good. 
To manage it via its panel is very easy n

that's what they put out.  Maybe call them direct?

 

This is funny.  
They have it but its nowhere to be found??

Ok, so it will be on the market in November.

Nothing available now.

You can buy them now from Geyserwise in Centurion.

I bought mine last week, R1500 for the full TSE kit with the Tuya module on it.

I also already bought 2 units, (Board Only) and replaced the boards in the TSE's

No stock toaday

CBI Astute will do up to 30A @230V on a resistive load, and up to 10A @230V for an inductive load. The geyser is the former, so it should work well for the OP's 3000W use case.

It is a rebranded TUYA so you don't need to use the CBi App, and some members have Tasmotized it as well, just search this forum.

Currently on special at Builders until 7 November for R449 (just first check online that your branch has stock).

In case anyone is using a Sonoff on their Geyser and they have Home Assistant you can use something called sonoff lan on the HA to connect and control all the switches, including connecting to the eskomsepush API to pull the loadshedding schedule to integrate it into your automation. Let me know if you're keen on a write up

Geyser is offline as we are currently loadshedding.

@uDuWaR i would love a bit of a write up / guide - i find this could be extremely useful for those who have even solar systems which split out non essential loads.

Hi @adams308

I am assuming you have home assistant installed if not then better get cracking, I have virtual box version setup on my gaming machine with a bridged network card (that part is pretty important) but you can run it in a number of scenarios. FYI the docker version of home assistant does not have the Add-Ons, these you will need. I learnt that the hard way. Also set the Virtual-box to startup on boot headless mode to make certain the HA is running all the time.

Next the installation of HACS is pretty straight forward please follow https://hacs.xyz/docs/setup/download/ or I used this pretty details write-up https://www.makeuseof.com/home-assistant-install-hacs-custom-addons/

Now you should see a HACS button on the left panel you can search for SONOFF and EskomSePush, the configuration of both is straight forward.
Sonoff you will need provide your eWeLink username and password.
EskomSePush you will need create an account and generate an API key. https://eskomsepush.gumroad.com/l/api

As for the Automation portion I have two rules, one for morning an one evening.
So either the geyser starts at 4 am or an hour before load-shedding on the condition that it's between 12:30 - 5 AM
Afternoon has a similar rule.

Finally I have an automation that turns the geyser off an hour after it turns on.

Let me know if you get stuck

Can you dumb this down a bit? 

The whole automation part. For a noob that is difficult. What triggers? Whats the condition? Do you use calendar?

Yeah sure not problems. please see the screen shots below.
I need to run my geyser twice a day for 1 1/2 hours to get a nice hot morning shower and bath for the young-one in the evening.

It consists of 3 rules, two the turn on the geyser one morning one afternoon and one to turn it off after 1 1/2 hours. I'll post the afternoon example and the turn off automation's.

The "turn on" consists of two triggers, one for 4 pm if there is no LS or 1 1/2 hours before LS starts (this is a calendar event that is created by the ESkomsepush's integration)

For the Condition and action there is one each as per below.

Turning the geyser off is pretty simple.

Let me know if you have any other questions.

As an alternative we've just released the Geyserwala Connect, it is a smart upgrade for the Geyserwise systems. It is a drop in replacement for the Geyserwise display panel PCB. 

The device was built with hobbyists and self-host’ers in mind so it is not reliant on cloud services and can be installed as a component in a self hosted home automation setup. Direct MQTT and JSON REST integration is possible. There is also a custom Home Assistant integration. It is also equally user friendly for everyday users who just want to control and set the timers remotely.

Feel free to have a play with our app demo: Geyserwala Demo which is both available on local network and internet (if you choose to link with cloud)

For more information see: Thingwala : Geyserwala Connect

I've noticed that your website indicates it works with the TSE1 model, but would it work on older TSE models?  Do you lose any functionality?

this is very interesting. 

 

i dont have anything installed currently to control the geyser. 

but in process of planning this. 

so what would all be required to have this Geyserwala to operate and integrate to HA?

I recently retrofitted the wifi geyserwise (one needed a drop-in PCB, and the other one a new display) to my two geysers. 5 minute jobs. Previously had the standard TSE1 and Delta models. PlumbIt online had great service and best prices amongst all (or so it seems). Geyserwise now runs via Tuya app and is great for remote enabling as PV dumps. If your existing geyserwise has a three digit temperature display (i.e. three digits showing even though temp shows without decimals) then the PCB retrofit works, else you need a new screen (a few hundred rand more). 

Is the Geyserwala basically a geyserwise  "copy" / third party product with additional functionality?

Thanks to Lloyd from @Thingwala, the Geyserwala Connect is now up and running on my older TSE Geyserwise model.

Subsequently integrated into Home Assistant, On/Off element functionality and water temperature available in HomeKit via the Homekit Bridge.
