  1. Gents, This is right up my recent memory and I am still sorting out minor issues. I used to have a Axpert MPPT ver II running really nicely and servicing essentials in my DB. Non essentials directly from grid. I have VERY limited North facing roof, so I opted for 2 SunnyBoys to supplement electricity. Downside: IF grid goes out, I was only running off the batteries. Lets add a SunnyIsland to get around that. Sunny Island ver 12 needs a backup box- Add that Sunny Home Manager ver 2.0 was needed - add that. I am in the lucky position that I can push 1
  2. , I was the fool in this chapter. I introduced a MQTT server on my network for IoT and one day when I was on ICC saw this tick and suddenly that light in my head lit up as I knew what I could do with the feed. So I ticked it and filled in all the info. Sure enough I protected my MQTT server by adding UID and PW layer but ICC did not cater for that. So I did not give it a second thought and signed off. Obviously ICC gave up after a period of time not able to connect and reported it. Today that snake sneaked up on me and bit me. Well its sorted now. I suppose th
  3. FOUND IT!!!! EASY TO SOLVE!!!! MQTT server was ticked: Although I have a MQTT server comissioned, but the interface does not cater for UID and PW which is required to publish to MQTT :-(
  4. I have not been accessing my RPi ICC for quite a period of time, so I do not know when it started to happen. Today I logged onto my desktop using VNC and notice this error messages: Reboot, restart.. nothing seems to make it disappear. I do not have solar connected to my system although used to have. SMA's provide solar power and Axpert charges batteries from input power - Axpert think it is grid, but could be grid OR solar from SMA Licence valid to 29-03-2050. Any ideas / suggestions from the clever guys?
  5. @plonkster Thanks for that advice. I am now making good progress in harvesting info. I am ultimately aiming to build a more sophisticated system to divert access power to geysers in turn. Like this just two notches up: http://mk2pvrouter.co.uk/
  6. So I guess my best bet would be to try and get the SBF Spot ( https://github.com/SBFspot/SBFspot ) to make available the readings for emoncms ........mmmmmmm but how? If it can send to PVOUTPT.ORG....there must be a way to send the readings to emoncms: OR am I over optimistic here?
  7. Ummmmm, Ummmmm,......think...think..... How do I get the readings INTO the Arduino? CT scanner? Then this will be much simpler: https://guide.openenergymonitor.org/setup/emontx/
  8. Maxomill, well, I have the STD feed into SMA site , but I actually would like to add graphs to the EMONCMS screen graphs, so I can pick irregularities up as it happens. I also have 4 DC switches, that I can flip, but I prefer the computer Monitoring route
  9. Having to purchase a Arduino to achieve that goal is a cheap run. @Sidewinder, I know I cannot bribe you with a bear :-), but how many coffees and Cokes for some pointers and help me to manage to feed readings into ICC EMONCMS? :-)
  10. @sidewinder, the SMA's do not have a comms port as suggested. :-( I am using the built in BlueTooth connection from SMA and Pi to establish the communication. No wires between the Rasberry Pi and and the two SMA's . I still have to check this suggestion: RS485->USB converter of @plonkster
  11. Like this: https://www.lazada.com.my/usb-to-rs485-485-converter-adapter-ch340g-chip-23021431.html Correct. I want to know DC; what is production. As you said: This is probably easier: BUT will I be able to feed readings into an emonCMS? - (Steep learning curve here for me!) :-)
  12. I have two SMA SB 4000TL 21 inverters. Each has two two MPPT controllers and I also have 2 strings of PV arrays connected. I therefore have 4 arrays feeding into the two inverters. Two are facing East and Two are facing West and the two Eastward facing arrays differ in size. I would like to monitor the power production PER array. Using the emonPi and emonTx with 4 CT sensors, can I monitor production per string? ( https://shop.openenergymonitor.com/emonpi-2/ ) + ( https://shop.openenergymonitor.com/emontx-v3-electricity-monitoring-transmitter/ ) This power will be DC and id
  13. [email protected] I knew there was a list but did not know I just had to stop ICC. Thanks Sent from my EVA-L19 using Tapatalk
