Yes you can do it separate, but then you have to make a second request in between.

I think you will need a different nodejs modbus. This one crashes when it tries to read an undefined modbus register, that’s the ‘difficult’ part

184

As info, i have à solaredge inverter and now for a week this app doesn’t work. My connection is via Wi-Fi. After contacting the support from solaredge today they told me that the modbus tcp doesn’t work over Wi-Fi anymore after the latest firmware update…

185

really, also got some update 2 weeks back, all is still ok. Do they ship release notes on the firmware ?

186

don’t see it here https://www.solaredge.com/setapp-inverters-firmware
https://www.solaredge.com/service/firmware

maybe you need to enable it again.

187

Try to ping it with another modbus app, modbus tcp on ios works

188

Is the name of the app you use “tcp modbus” for iOS?

189

Yes

190

Hey, can you try this on node https://gist.github.com/biemond/87403d5c9a28ef89a6ec3e5142ec4c85

it should not care about wrong modbus entries and detect all the meters and batteries.
if this works for you I can continue plus I don’t keep the connection open because it is fast and it blocks other tests/ modbus programs.

But as you can see, there are different modbus registers I guess.
My firmware of battery and BMS are newer

192

thanks so you have only 1 batt or not, for me it gives me 255 on the 2nd also a different meter .

but nice now I can compare it.

193

not much difference. this is doable.

194

1 HD Wave 4000 with display
1 meter
1 battery LG 9.8

195

nice, also got the storage flows working, will go for

  • Maximize self-consumption
  • Time of Use
  • Charge from PV+AC
  • Maximize export

in 1 flow actions will handle the above.

196

I think will start over with homey sdk3, use typescript and re-use your code.

198

so currently you cannot use homey app and something else. homey app will lock modbus. I am making some changes so will do a poll every x seconds and close the connection.

but I see 1502 port so this is tcp and it should work over ethernet.

199

I’ve been testing everything, restart inverter, disable modbus tcp and enable again in inverter. Remove device, reinstall app… worked like a charm before installing my load balancer and new software was downloaded to the inverter according to my electrician. I’m not an programming expert unfortunately, out of ideas…
The inverter is connected via Wi-Fi
You don’t see anything strange in my setup?

200

looks ok, but remove homey devices and restart app, remove load balancer , check ip of invertor and can it be on your wifi you did something that other devices cannot do something on others . some firewall rule.

I see modbus on 1502 port so this is networking and only used by networking. so I guess this is some routing or firewall router issue.

201

I am using the cable , not wifi and made sure firewall is ok.

202

I have google wifi mesh. But no change there compared to when it worked before… Strange…
Can it be any protocol for communication in the meter setup in the inverter that has changed?

203

maybe they changed the device ID.

In the test version of the Homey Solaredge App you can change the device ID if you add your inverter as ‘multiple inverter’
default is 1
