Hi, Thanks for the reply. Not yet, I sent the cable back to Geewiz for a replacement as advised by solar assistant support. I should be receiving the replacement cable next week. I'll keep this thread updated. Thanks a lot!

Thanks a lot, Solar Assistant Support is currently busy trying to assist me, so if all else fails, I'll try that as well. Thanks a lot for the advice! I will update the discussion as we go along.

Oh, so I must replace my current Sunsynk logger to test?

Thanks, but my inverter doesn't have such a port at the bottom.

Good day all, I'm writing in hopes that someone will be able to assist me. I bought the attached from Geewiz, which had Solar Assistant already loaded on the Raspberry Pi 4. The setup was simple: I plugged in the device at my house for the configuration, loaded my account (to set up remote access), and moved to the inverter. I'm trying to use the inverter values for the battery, just to get everything working before I attempt the next step and plug in the Battery Cable in the RS232 port of my battery. I'm accessing the device without an issue, but I simply cannot connect to my inverter inside the "Configuration" menu. It just says "No response address 1 (It cycles through to 15)" and then I get the "No response, retrying in 15s" error. I have tried the following: Changed the Modbus ID on the inverter itself from 0 to 1 Plugged my RS485-to-USB cable into the RS485 port, instead of BMS2 (as instructed by Solar Assistant Support) Restarted my Raspberry Pi 4 multiple times Reinserted the cable (I used all USB ports and restarted between every change) My Hardware: Inverter: Sunsynk-50K-SG01HP3-EU-BM4 Battery: SUN-BCU-M-080H1-OT Can someone please assist? I'd greatly appreciate it. Thanks in advance!

Ok great, thanks a lot Muttley! I appreciate your help :)

Thanks for the rapid response Muttley! I bought the same power supply and DC - DC voltage buck converter as per your original post. I always ran it on 24V, but I changed it to 18V now without any success. Maybe I should just accept the new MV ranges and recalibrate?

Hi all, I'm having a bit of an issue here. My tank volume stopped calculating correctly and just showed it was full (I didn't fix the calculation yet, so it shows 10284L when full). Upon investigating, I discovered that the MV has suddenly changed after months of reading the same values. We did not change the tank or anything like that. The last "loss of data" is a result of unplugging our whole network to protect our devices from lightning. After restoring power to our network equipment, the voltage had jumped quite significantly. I did not cut the power to any smart device, just a simple network disconnect and reconnect after a few hours. Does anyone maybe know what the issue could be? I can, of course, just recalibrate, but I'm really curious to find out the cause of this change. I'd appreciate any kind of insight on this.

Can you please link the post where one of the forum members de-soldered the chip and replaced it with an ESP32? I'm done with this Tuya rubbish

Hi @fourwp , I have looked at my temps from Home Assistant from beginning of June, as that was when mine was last working without the element. I have attached the results (we were using warm water as well in this timeframe. It basically took 4 hours to reach 60c from 49c I do have a question though, how did you add your Magneto / EMS to Home Assistant? I tried after receiving my replacement unit, but can't remember what I'm doing wrong haha.

Your suspicions about the DFRobot sensor were correct. Thanks for that! I'll be doing the other 2 JoJo tanks as well that's on out farm.

Update: So the issue was indeed the INA219 sensor from DFRobot. When I changed the INA219 with the suggested generic sensor, everything worked, even the tank volume started updating! Thanks especially to @Muttley for your help! I'm going to experiment on the "days of water left" and the "Tank Refill Rate" This is amazing!

Hi everyone, I finally got time to change the INA219 sensor and things are looking very promising. I'm just waiting a bit for more data and then I'll report back. Thanks for the help!

Just an update, I have received the INA219 from PiShop and will be replacing the DFRobot this weekend 😁

LOL, I really hope that won't be the case 🤣🤣 I will surely do so, thank you so much! 😁
