Hi pavol14pavol, I removed everything at this time because I'm finished with it for now. It's impossible to make money and I've gone broke with it. As I'm currently unable to offer full support I took it down until/if I can figure something out.

I sure would like to know what all that is translated into English. Thanks.

Sad to hear that Sad . Will you still provide online support?   Are there any controllers built but not sold?

Yeah was a sad day. Will definitely still support whats out there and the forum will remain as it is. At this time I don't have a full controller for sale.

Hi johnrc, there's a couple reasons and I do hope to bring it back.

I don't even sell them anymore, last sale has been at least 3 months, well actually just shipped the last on the weekend but that only happened because I took it down and giving a deal lol. There's interest but the cost is just too high, $10 more you get an Apex, even I would probably choose the Apex.

v5 also hasn't been so great to me. Since there has been a lot of issues with the I2C bus locking up that didn't happen in v4.2. v5 is much faster so I think its a timing thing but can't figure it out, it's a troubleshooting nightmare as not everyone experiences it and I've personally never had the issue. I've been working on it and some changes fixed it for some but not all. Most users are actually using v4.2 as it ok. Which version are you running?

I thought about just going back to v4.2 and adding a few of the features from v5 but that isn't going to help any. Bottom line is I screwed up and took the wrong path, back in the day when things were simpler and cheaper I was actually happy with sales, now it's a joke and won't get better.

I also don't have anymore to sell and don't have the money to restock when things will just sit in the drawer.

Then the other downfalls, no full web, display isn't instant and not much factory equipment can connect so no reason to choose DIY over Apex when price is the same. Of course now there is no interest from DIYers which was the whole idea.

So I'm going to try once more, I've learned a lot and know where and how I screwed up and think I can nail it, just can't get carried away.

With the planned changes the controller and a good AC power bar PCB will be as low as $130 and blow away what I have today. ;)

Well to put things in perspective...

I’m a member of one of the largest forums in holland with about 10.000 active members who run one or more tanks (fresh and salt mixed)
At best there are about 100-200 people who run a full controller on one of thier tanks.
There is one other guy on that entire forum who runs a DIY controller that I know of.

All the other people either do everything by hand or have stand alone equipment (jebao dp4 dosing and/or tc420 ledcontroller) or Just use programmable outlets which you buy for under €10.

So you have a very limited client base, even with the plug&play kits.
Stand alone equipment for a standard fresh water tank (dosing, outlets and LED control) would cost about €80 over here, so €50 extra for a touchscreen isn’t all that bad.
The “challenge” you have would be selling the screen so to say

Hi fietsenrex, I agree the market isn't that large for all-in-one controllers and many shopping can't afford one. My first year when prices were at their lowest I was averaging at least 5 a month, as the package grew sales dropped, the new energy power bar was the final nail. I think many are interested in all-in-one but don't follow through because as you mentioned everything has a standalone controller and cost doesn't justify.

Most people who have my controller seem to use outlets, ATO, feeder and dosing pumps. Then the real DIYers also typically use some LED channels and DC ports for light cooling fans. Some also want auto water change, the analog ports are useful for things like this and that's why I added the maintenance mode so the system could be started up better.

I'm at a point where I'm 100% happy with the features, I'm not even considering controlling power heads or other equipment anymore. So if a customer only has to spend $150 to be up and running vs $450 its a new game. Robo-Tank has never been a cheap system, the lowest to get running was $250 with display etc... and I did well. I know I can bring price down to $150 and the controller will be more than it ever has been.

I'm very confident you won't find anything like this for $150 that will ATO, AWC, 8 outlets, 8 dosing, 16 LED's, feeders, stirrers and much more plus the best support you'll find anywhere. ;)

Well in my opinion, things don’t have to be cheap.
You have to get your moneys worth.
With that said I don’t think the price tag isn’t that bad for all those options, but not everybody wants or uses those options and therefore aren’t willing to pay for it.
As for support, I think you nailed it.
Always reasonable fast (there is a timezone difference) and most of the time pretty accurate which solves most problems instantly

Overall the controller will be simpler which brings the cost down so I'll still be making what I need and it'll be a lot less work then now.

The cost to add extra ports is very low that's why I add lots, this time it'll be done in a better way. That's my advantage and what most people were drawn to, even if they don't use everything it's nice to know other things can be done without needing to spend more. For sure not for everyone but if price is right a lot of DIYers like a project.
