freezing values from multiple devices of the App in HomeyPro (cascaded SUN2000 inverters)

[cristeam]

Hello,

I have 2 SUN2000-6KTL inverters connected in cascaded setup: Master that has smartpowermeter + battery has ID=3, and a slave inverter has slaveID=1. The external connection is a Wired dongle with 1 IP in LAN (in inverter-master). When using a modbus simulator, I can access registers from each inverter by using the same IP address and only have 2 different slaveID (1 or 3). In HomeyPro: I added 1 device with IPx, ID =3 type sun2000 & batt => and I get the correct data. When I add another device with the same IPx, ID=1, type sun2000 => I see values only when HomeyPro reboots. Then I sometimes see only the active power updating, but battery-level => it never gets updated. Only if I reboot homey.

yep, don't support s-dongle with 2 inverters. current way cannot handle it. I know the new Emma works better with this and responds in seconds. s-dongle is very slow and cannot handle too many connections. plus fighting for the connection.

I don't have these inverters so it is hard to test this.

I can do any testing you need. I suggest we need for these slow sdongle to:

• have a large modbus-timeout value (2 seconds) - better would be to have this parameter in advanced section for device, next to ID;
• to change the polling interval (or provide this parameter to App.
• Another issue would be to chain the modbus queries with a certain delay (1sec) between queries of different devices (if this is possible in Homey platform).

yep, already have a slow startup like 5 sec and 2 sec on reading any register. poll once per minute.

indeed need to share the connection and do 1 by 1 .
I need some test environment for that .
