Hi, I can't recreate you scenario. The MCP23017 will retain it's state until told otherwise by the node
So restarting Node-red has should not momentarily turn the output on.
How are you using the MCP23017 - is then any other circuitry involved
Please can you attach your flow
Hi willhey, Thanks for your reply. As far as I know, there are two nodes for Microchip MCP23017 one is the node-red-contrib-mcp23017 that is 2 years, 3 months and I can't seem to be able to install it and the other is node-red-contrib-mcp23017chip, that it installs fine and works. For a end user point of view there should be no difference on the flow except that node-red-contrib-mcp23017 has the outputs inverted. Because I'm dealing with a rack of OPTO22 G4PB16H solid state relays connected to the MCP23017 I need to have the outputs inverted. In other words, instead having a Low I need a High when the node loads or inverted outputs.
Here is the test flow were I try to bring the outputs to high state :

Hello Willhey,
apparently I have the same problem as Lisitan-o. It would be great if they look at my flow.
Actual state: after pressing the first "ui_switch", all 16 relays are activated.
DESIRED state: after pressing the first "ui_switch", only the relay connected to the "ui_switch" goes.
Reproducibility: Call the board, press one of the 16 "ui_switch".

Hello @Lusitan-o
did you get to your issue (MCP23017)? Are you still using this node? If so, I would be happy about your solution.
Hello @willhey
Do you have a solution or did you discover a mistake in my flow (my comment from November 24th, 2019)?
Best regards from Germany
I've created a complete rewrite of the code. If @willhey accepts my Pull Req., there will be a new CheckBox : Invert.
Until than, you can manually install / update the source code from here: https://github.com/PizzaProgram/mcp23017chip
Could someone please tell me were to modify the code to have the outputs inverted? I'm a beginner and any baby steps would be appreciated. I need to initialize the outputs HIGH when chip first powers on and a low to turn ON. I have some relays connected to the mcp23017 that use inverted outputs and require LOW on the pin to be ON and a HIGH on the pin to be OFF. I've tried to use a flow to inject once at start 1 to turn all outputs OFF, but when the node-red starts it momentarily turns the relays ON.
Thanks.
