Just have my own PV plug and play, works great… Would love to have it in homey as well. Already have Solis which is great in homey pro
Unfortunately it doesn’t work very well here and that is all due to the open DTU. I have a relatively spacious house with 60 solar panels and 15 inverters. After purchasing the DX-DTU I found out that the device unfortunately only supports 10 inverters. Too bad, but then we try that first. After fully completing the installation (also on the homey side) the first data is visible in Homey. Unfortunately this is limited to only 3-4 inverters. After moving the DX-DTU other inverters became visible which indicates to me a signal range problem. Apart from the fact that I have to purchase a second DX-DTU for all inverters, I don’t expect it to work fully for all inverters.
Unfortunately I have no programming knowledge, but I do have a ‘Hoymiles DTU-Pro (wifi)’ device standing and running. All inverters are visible here and the data (although not live and per 5 minutes) can be retrieved from the hoymiles app. Isn’t there a simple link with Homey for this? This data will be in the cloud (behind a hoymiles account)?
I would contact Diamex and tell them about the problem. They may have some good tips on how to improve the range, e.g. with a stronger antenna.
I don’t have also no programming skills, but in general it seems to be possible to receive the data from the Hoymiles Cloud or even directly from the Hoymiles inverters with integrated WLAN (HMS-XXXXW-1T/2T). After some research I found some Home Assistant integrations. If they really work and what is exactly needed beside Home Assistant, I don’t no.
EDIT
Btw, have you tested if it helps to increase the transmission power? As far as I know, the transmission power is set to “Minimum” by default.
