JayMardern Posted September 18, 2023 Share Posted September 18, 2023 @Zodiac69 @Yuri Thank you! I'm not running any HA instances (I've decommissioned my always-on-servers in an attempt to reduce my energy footprint to deal with load shedding!); presumably this isn't possible with just the native Tuya/SmartLife app - but perhaps it's time for me to spin something up again for this kind of thing Quote Link to comment Share on other sites More sharing options...
Zodiac69 Posted September 18, 2023 Share Posted September 18, 2023 Hi JayMardern I use an RPI for HA, but i am in the process of moving to an old Thin Client - HP520t with an external SSD. Quote Link to comment Share on other sites More sharing options...
Patrick OReilly Posted September 18, 2023 Share Posted September 18, 2023 (edited) Hi all. Excuse my inexperience - I'm now very new to Home Automation stuff.... I have the CBI ASI isolator in front of my geyser. It's working 100% with the CBI App. Cool, scheduling, etc, but all manual monitoring so far. Now I've installed Home Assistant. I have figured out from this thread that to get HA talking to the CBI Isolator, I need to pair it to the Tuya App, and then use the Tuya Integration on HA. Fine... I'm just having no joy getting the Tuya App to pair with the CBI switch. I get the switch into paring mode, open the App - and then wait till 2 minutes expire with no joy... I can re-pair the Switch to CBI App no problem. So, I know I am getting pairing to work. But it just won't play ball with the Tuya App. Any clues - please ?

Yuri Posted September 19, 2023 Share Posted September 19, 2023 Hold the square button for 5 sec then release it the lights will blink fast Hold down the square button for 5 sec once more now the lights will blink slow Use the app's slow blinking set up this always works for me I also select Socket (Wi-Fi) for adding device Quote Link to comment Share on other sites More sharing options...

Interesting. I'll give that a whirl... Thank you. Quote Link to comment Share on other sites More sharing options...
crudler Posted October 31, 2023 Share Posted October 31, 2023 Just installed a CBI asc on my geyser. Seems to be working fine. Im using the tuya smart app. Under electricity stats I can see a voltage, but no current? What would cause that? My geyser is hot so it must be drawing a current Quote Link to comment Share on other sites More sharing options...
Patrick OReilly Posted October 31, 2023 Share Posted October 31, 2023 Perhaps it is already hot so the thermostat has switched off the element? You’ll only see current when the water cools down and needs to be heated. JayMardern 1 Quote Link to comment Share on other sites More sharing options...
crudler Posted October 31, 2023 Share Posted October 31, 2023 Ok good point. Maybe I jumped the gun. I'll leave it over night and look again in the morning Quote Link to comment Share on other sites More sharing options...

I'll leave it over night and look again in the morning Check once you've used the hot water tonight and you should see both Power and Current produce values above 0, for as long as necessary to re-heat the balance of the water. Voltage will always remain at supply-voltage when the geyser is connected. Edited October 31, 2023 by JayMardern Quote Link to comment Share on other sites More sharing options...
crudler Posted October 31, 2023 Share Posted October 31, 2023 Still showing zero. Very strange. Definitely drawing power because I can see the usage spike on my inverter. Quote Link to comment Share on other sites More sharing options...

What happens if you use the CBI APP? Seems there is a problem showing the recorded amps/power used. Quote Link to comment Share on other sites More sharing options...
crudler Posted November 1, 2023 Share Posted November 1, 2023 I'll try. The tuya smart app works with my other device on my pool filter Quote Link to comment Share on other sites More sharing options...
crudler Posted November 1, 2023 Share Posted November 1, 2023 No luck... i tried the CBI app and it does the exact same thing could it be a wiring issue? The LOAD from the controller goes into an AC Contactor before it goes to the geysers - could that be the issue? Quote Link to comment Share on other sites More sharing options...
Zodiac69 Posted November 1, 2023 Share Posted November 1, 2023 (edited) The Full load must go via the ASC. With the way the ASC is wired, you only drive the coil of the contactor, will not even show as the contactor coil power consumption is very low. (N) to N on ASC (N) to A1 on Contactor (L) From breaker to input of ASC Output of ASC to Contactor to A2 and to the "Input" of your contactor. Do you have 3phase or is it 3x geysers? Your total load can not be more than 30A if it is single phase. If you have 3Phase, then you need 3x ASC units, one per Phase. I do something similar.. I have two ASC's, one per Geyser as i stagger my load, and two contactors, one contactor per geyser. In my case i have wired the geysers to that i break Live and Neutral via each contactor.

I'm pretty sure this wiring is the issue, As a side-note, I've used the CBI, Smart Life and Tuya apps with this same CBI Astute controller (complete with it's annoying flashing light!) - and it works perfectly under all 3 apps. It's a fantastic piece of hardware IMO. Quote Link to comment Share on other sites More sharing options...

OK i understand. All my time switch is doing, is making the contactor close a circuit so the geysers are powered. The time switch doesnt carry the load of the Geyser. gotcha.... I am single phase. yes i have 3 geysers so its a rewiring project to get the consumption data - not sure if its worth that. M main goal is I made my geysers smart, and I can integrate them into HA. Getting consumption data would have been a nice to have thanks Quote Link to comment Share on other sites More sharing options...

Getting consumption data would have been a nice to have thanks It took a while to find out the current does not go through the CBI. If you perhaps reduce the current via 2kW elements the the CBI can switch them directly without the need of the relay. This will then provide the power which you would like to see. It seems you have enough space even for another CBI. This can give better control as 3 geysers on at the same time is quite a big load. We all try to stagger geysers coming on at the same time.

Bunta Posted February 19 Share Posted February 19 Hi All, I just installed a CBI Astute and all working well with the CBI Home APP. I see that the CBI Home app has options for other Home switches. Does anyone know what Light switches can be controlled via the CBI Home app? Or should I get Tuya Light switches and moved the geyser and lights onto the Tuya app? Thanks Quote Link to comment Share on other sites More sharing options...
JayMardern Posted February 19 Share Posted February 19 The Astute's form part of the Tuya/SmartLife ecosystem - so any compatible devices can be added. I use my CBI's through SmartLife and have been extremely satisfied. Quote Link to comment Share on other sites More sharing options...
