same issue, flick and stuck relay. no bus lock alarm. last for two years.
only work fine without any expansion module. almost give up, no luck.

It looks like it is working right when it is in the tank.

How its ups and downs even in cup measurement. Is this in measure tolerance range?

yes

rimai wrote:Yes, that is the patch.
But this code:

Code: Select all

ReefAngel.CO2Control( Co2, 6.40, 6.45 );

Should be without the decimal:

Code: Select all

ReefAngel.CO2Control( Co2, 640, 645 );

as checked code. already typed as you said. mis-typing in post.
but relay still flash right now. doesn't help.

just put probe in cup for a week. see pic below.
its ups and downs from 7.43~7.88. how this happens and what cause that?

will try in following days. See what's happened

the pic shows problem happens in my ph expansion measurement. need help

But why my ph expansion going down every day Saturday 7.6. Sunday 7.5. Monday 7.4. I just swap ph expansion to my main last Saturday. (used to connect CA reactor, but saw same problem.) It's not possible for my main tank down to 7.4, used to be 7.7 or high in mid of day (connected and measured by he...

Ok will change later

I think there is a problem with the calibration of your pH expansion. There is a patch to be released. What it is doing is actually saving the setting of the ph expansion into the head unit pH values. I would recommend either using the dev branch of the libraries or we hard code the calibration val...

Firstly I’m very appreciate RA+. This stuff makes my hobby much easier than I thought. Most of daily work are rely on this small magic box. But Im getting frustrating with this box since a new PH expansion introduced into system for my new Ca reactor (for CO2 control) First. My salinity expansion ou...

not capture pic, not in home right now. Will check latterly afternoon

patched with link code just now But nothing improved. Strange. Missing something? And re-calibrate again and again

Another issue with my ph expansion module. Not sure if should raise another post
Ph expansion can't maintain ph calibration data when after upload code. For exp. before load ph expansion shown 6.5 and after shown 8.03.
Should re-calibrate every time when update my pde

means this probe can last less than a year like ph probe?
Let me try a new one and see what's happens

What happened with this probe. Always working fine since added ph expansion. Any other root cause?

Put into a container of tank water. Show 6 . Re calibrating, zero

Re-calibrating salinity and reads zero

the salinity module was introduced about 8 month ago. It's working find since then even with serval time code update. This is first time acting like this way after ph expansion hooked up. Just tried to connect salinity again without hub. But still shows 6. Reboot head and connect again , still 6. Di...

i checked my portal and find another interesting thing
salinity drops very slowly from 25 Oct to 28 Oct and stay in 6 from 4pm in 28 Oct.
seems very strange.

hi i'm very appreciate if some one know how to solve my problem with my salinity expansion. last week, i just hock up with a new ph expansion to monitor newly added Ca reactor. after 3 days try out. ph expansion works fine with ca reactor, but my salinity doesnt work at all. now it shows 6 what ever...

Yes changed to all original usb cable.. I just plugged on 6 ch dimming module this and next week. Will have a try after holiday. Don't want tank crash when out of holiday.

today try many hours with RA+ with different condition. unplug diy Relay box and dosing pump. but still keep 16ch dimming and 6ch dimming expansion functional. after about half day of running. all ports in 16ch dimming expansion locked on (all ports stacked with 5V output). but 6ch dimming expansion...

oh that's in correct condition. Still no idea what's wrong

Little crash last night. 16ch module turn on all ports from early morning and Over dose alk and ato. May happened from 4am check from portal (sal doesn't work in 4am just 5min ). Over dosing may last 3hours from that and stop manually after wake up

i think I find the root cause. Its working fine since disconnect 6ch module about 2 hours ago. Question is how can I setup jumper for these two dimming module. Now I just leave Jp1 blank in 6ch module and plugged JP1 in 16ch module. Is it correct?

--Colin

need to use Hub. otherwise meaning less for me.
if finally cant work out. i may purchase another relay box. but it's in worse case due to painful experience change all plug to US socket

May bad usb cable cause this issue? Should I get some other new one just for try. Or play station 3 cable should work? Seems same connector

3 come along with 16ch and hub last month. 1 purchased last week cause need a Long
lead for salinity
