The electricians used ChatGPT for instructions on wiring the RJ25 cables and mixed up the pins ..... All is fixed now that the pins are in the proper position according to the manual!

Thank you patrickduis, jschulze, and David_2! I've finally got real, correct values for power. It turns out the most recent hurdle was just not having the right addresses, and once I got the spec sheet, everything started lining up. You all were an immense help with figuring out the addressing...

I have good news! They got back to me, with a spec sheet. I tested some of the addresses, and Im getting data although it doesn't make a lot of sense. I don't have time to test everything today, so I'll update this post with more info when I start testing again tomorrow.

Its an HGR41EW energy meter from Hager/Rayleigh, but the spec sheet is for HGR43 because I can't find a copy for the 41 online. Ive already emailed and called the company, but Im waiting for them to get back to me :/ If you somehow manage to find it, good on you, because in googling "hgr41ew...

I agree about the shaming. It caused me unnecessary strife, imagine how much collective stress it's caused across all the electricians that have had to deal with it!

Okay, I've got it set up now, and its giving me refreshed voltage! Unfortunately changing the address to 5 results in wacky numbers (all the way from 1e23 to -9e-33) being returned, changing to 7 has the same result, and changing to 30005, 30006, or 30007 leads to no valid slave responses...

Im trying what worked with the voltage, which is cutting out 30000, using function code 04. Trying 30022, using decimal to hex to get address of 7546 gets only errors. Same with 30022-1, address of 7545 also is only errors. When I ignore 30000 and use the 22 and 21 without converting from binary...

I've tried both adding and subtracting one, and this brings me to my next issue: only even addresses work for voltage (although they do return a real, correct value) but for current, active power, reactive power, etc, nothing works, +/- 1 or not. I keep getting values of 0 or near 0, when Im...

I switched to 4, and it (mostly) worked, thank you! Im still receiving a bunch of junk 90% of the time, but on the occasion that I do receive a response that begins with 01 04, its giving me the right numbers for voltage.

Shoot, I just realised I forgot to attach the other image. The data structure is float reverse word (2301), I've been using this website and Chatgpt to convert the data Im receiving properly. I understand why heavy corporal punishment is given, I feel like inflicting some myself when I have to...
